What new methods can be used to study the genotoxicological activity of water? can share

Hello, i wasn't in class today, so i don't know how to do this homework. Your is really really welcome

HI. Have any genes associated with emotion and or conscience been identified, if so may I ask which please. Also, if so what role are these genes known to perform. Do they play an active role in the 'performance' of those subjects, or do they simply facilitate the demosntration of them as they occur? Thanks Martyn

Hey, are there more than 2 sexes? I recently talked to a person who told me that it has been scientifically proven that there are more than 2 sexes biologically and that the biological sex is a spectrum, so I wanted to ask if this is the truth? Btw: it was definitely about biological sex, not gender. My ideas: I know men have XY and women have XX chromosomes. I know there can be mutations in which humans can have XXY chromosomes, but is this called the another sex? especially when this person isnt fertile. And if you include all mutations of the sexgenes, would you get a Spectrum? If you were to ask me spontaneously what the definition of a sex is, I woul…

Stanislas Dehaene is an important psychologist and cognitive neuroscientist, but I think that he is grossly mistaken in genetics, in the following passage from his book, How We Learn: Why Brains Learn Better Than Any Machine . . . for Now: He goes on suggesting his idea for the paradox resolution, but I think that there is no really a paradox, just a mistake in the assumption on how genome works.

Introduction: There is a recurring debate about homosexuality - whether it is an accepted biological genetic cause - or whether it is a "moral deviation" caused by the social environment. In this topic, I come to argue that, although homosexuality does have a genetic basis, it seems to be largely environmental NOTE: I do not believe that homosexuality is a "moral deviation" and it is far from that, but it seems to be largely influenced by the environment without a doubt. Genetic cause: Much like any other trait, homosexuality is a result of genes and the environment. One way to estimate the influence of biology is to use something called twin studi…

What are your opinions about CRISPR gene editing technology, for a school assignment https://forms.gle/g9UVN9eRPrEheUtDA

Through commercial DNA testing, I found that this lady is my 1st cousin once removed or my second cousin, We share 356.3 cm and the longest segment is 44.99. Her mother and my father's biological mother were sisters. Odd thing is I share 90.1 cm of "X" chromosome with her. More than I do my maternal half sister. I do not know who my father's biological father was as of yet. I sent my DNA to a geneticist/genealogist who believes that my father's parents or grandparents may be closely related. So I am searching for an explanation as to why I share so much "X" with my father's maternal cousin. Tasha

What is the minimum population of humans that is necessary to maintain a stable population without significantly increased rate of genetic defects? I do know that the Amish are descended from a group of 200-something individuals and Ashkenazi Jews descend from a group of some 350 individuals.

Hi, I was just wondering, is there any correlation at all between parents' endurance/long distance running capability to their offspring's endurance/long distance running capability? How much of it is all due to genes and how much due to the environment and epigenetic influences, gut microbiome etc.? Based on available data, what proportion of elite athletes (i.e. middle/long distance runners specifically) have children who are slow/unathletic in middle-long distance running? What proportion of elite middle-long distance runners have parents who are unathletic/slow runners? What can the latest scientific data tell us about the heritability …

Bit new to bioinformatics and just wondered how useful PREDICTED amino acid sequences derived from the genome are (I have found several in NCBI). If trying to BLAST these sequences to find conserved sequences, are the results going to be of use or is it better to not bother with these sequences at all? Thanks, Caz

I have a belief that changing DNA can alter organ production. For example if I replace the Y in XY with a X to equal XX; the long term result will be the former XY person growing female organs. Did I get it on point? Looking forward to your replies.

As I write this I researched on coronavirus. The MRNA is genetic material that makes the coronavirus multiply inside the infected one. Now I wonder if this MRNA can be used to shut off SRY gene and to start multiplying XX chromosomes? What do you think about my Theoretical Idea?

Show me the proof that inbreeding is wrong? Or better yet, show me the proof that inbreeding leads to genetic defeats? To me it sounds like a few narcissists scientists got together and decided to play god because they saw a co-relation in the two without taking into account the environmental factors as well as what you eat that leads to genetic defects. If you were in Chernobyl, then it would lead to defects. To me it sounds like a few people that want to prevent us from having kids at all or having more of them so the rich stay rich and the poor stay poor. To me it sounds like someone is playing god so we don't engage in the act of reproduction but they use our kid…

IF two human siblings have a child, what is the average risk of it having a genetic disorder?

I have a question, the process of Homologous Recombination creates a unique genetic individual from 2 parents from their sperm and egg. Would it be possible to take an animals DNA, and by comparing it with its mothers and fathers reverse engineer the DNA that formed its DNA? In other words reproduce the genetics of the haploid sperm and egg cell that went on to create the diploid animal? Has this been done, or are the tools available to do so? Would algorithms be able to be produced that could do this? Thank you for any relevant research on this, I'm doing advance genetics next year with a focus in animal cloning.

Hi, can you explain the various steps used in this article in steps? For example "and their relative quantity was estimated by running 5 μl DNA on 1% agarose gel for 25 min. "i think indicates electrophesis https://www.frontiersin.org/.../fmicb.2021.567961/full Molecular Analysis Before DNA extraction, root samples were washed from CTAB buffer and then homogenized in 2-ml Eppendorf tube using two 3-mm tungsten carbide beads in Mixer Mill MM400 (Retsch GmbH, Haan, Germany) at 30 Hz for 5 min. The PowerSoil DNA Isolation Kit (MoBio, Carlsbad, CA, United States) was used to extract DNA from homogenized root samples following the man…

Is SARS-CoV-2 a variant of SARS-CoV-1 or is it a strain or new species?

Can someone please reconcile the following statements? - First cousins, on average, share 12.5% of their DNA. - Humans and Chimpanzees share 99.8% of their DNA. TIA!

Hey guys, so i´m supposed to develop a method which could help detect genes that can replace an essential gene in yeast by overexpressing them. Does anyone have any ideas as to how i should go about that. i need to figure this out until tumorrow lol, and would appreciate any ideas. thanks in advance

I have just learned about Lulu and Nana And about how they were parts of the CRISPER Experiment And I Don't Really Under Stand What It Is So Could Somebody Explain

Hi, anyone please make me clear if it is possible to extract DNA from bird feathers by magnetic bead-based DNA extraction method ? If any kind of literature or protocol is available on it then kindly share the link also. Thanks in advance.

All I can find on the internet is the cons of being mixed race... ((All the negatives that come with being bi-racial)), so I was wondering if there's any actual scientific sources that list the pros/the positives? I'm sure there's some advantages that come with being a mixed race individual, but finding actual information ((for me anyways)) is quite hard when compared to all the bad information out there when it comes to being such... Excuse my bad grammar by the way. : ) I am sorry for that...

Actually out of my comfort zone, but have been interested in the science of abiogenesis and evolution from when I started visiting science forums. So some questions that I have thought about. Is cancer, or can cancer be described as evolution gone mad? Can it be inferred as evolution? I once had a physicist named Dr Karl Kruszelniki make a prediction that in time, we will be living forever. At the time I thought he was crazy despite the high reputable reputaion he has In Australia. I still think he is crazy on that score https://en.wikipedia.org/wiki/Karl_Kruszelnicki and https://blogs.unimelb.edu.au/sciencecommunication/2012/09/14/life-death-and-disagreeing-wi…

In 2015, a group of scientists discovered that whether or not we get genetic disorders is determined around five days after conception when our DNA gets its epigenetic profile (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4464629/). In 2017, I discovered the causes for over seventy of these epigenetic profiles. In 2019, I realized some of the practical benefits of what I discovered. Then I realized that what I discovered was something much bigger than what I originally thought.
