vcu Posted September 3, 2012 Share Posted September 3, 2012 Which of the followingstatements about polypeptides is not correct? Answer their structure is influenced by hydrophobic effects they are synthesized inside the endoplasmic reticulum they can recognize specific DNA sequences their function can be modified by phosphorylation they can fold to form helices, sheets, coils Which of the followingis not true of ribosomes? Answer they have codons in ribosomal RNA ribosomes catalyze peptide bond formation ribosome structure requires rRNA binding to proteins they can bind to transfer RNA they can bind to the 5' end of messenger RNA The cell membrane formsas a result of Answer cholesterol binding covalent bonds between head groups hydrogen bonding between fatty acid chains hydrophobic effects on phospholipids assembly directed by membrane proteins Which statement aboutcarbohydrates is incorrect? Answer can be attached to proteins can mediate selective transport into the cell can be used to store energy can be attached to lipids can provide structure for cells Which of the followingstatements about electron transport used for respiration in animal cellsis incorrect? Answer produces CO2 involves proton transport consumes oxygen all answers are correct initiated by oxidation of NADH Which of the followingis not true of DNA? Answer it is usually found as two anti-parallel strands it is located in the nucleus it is a template for synthesis of messenger RNA it is a template for the synthesis of DNA its nucleotide base-pairing is mediated by phosphodiester bonds ATP Answer is an essential enzyme acts as an electron carrier base-pairs with thymidine nucleotides contains high energy bonds all answers are correct A mutation in thenon-coding region of a gene Answer can change the expression of the gene product can change the structure of the gene product can't have a phenotype can't be inherited A gene Answer is a trait is expressed only in the presence of RNA polymerases is assembled from a set of essential amino acids is replicated during the G1 phase of the cell cycle changes its information depending on the environment of the cell Alleles of a gene Answer have the same DNA sequence can produce different versions of a protein mark the start and stop of transcription are always in the same DNA molecule Link to comment Share on other sites More sharing options...
doG Posted September 3, 2012 Share Posted September 3, 2012 Do your own homework!!! 1 Link to comment Share on other sites More sharing options...
fresh Posted September 3, 2012 Share Posted September 3, 2012 Do your own homework!!! yes, this buddy is absolutely right, Do your OWN homework !!! this is not a 'homework answer' forum. Link to comment Share on other sites More sharing options...
ewmon Posted September 3, 2012 Share Posted September 3, 2012 vcu, go back and re-format your post so it's readable (squeeze the answer lines together, and separate the problems from each other), then give us your answers and your thinking at arriving at those answers, and we'll help you from there. That's what Homework Help is about. We don't give answers; we help you think to arrive at the answers yourself. 1 Link to comment Share on other sites More sharing options...
Greg H. Posted September 3, 2012 Share Posted September 3, 2012 These are the kinds of people I usually give the wrong answer to. I'll refrain, and merely echo the calls of my forum brethren above - do your own homework. We are not "phone-a-friend".We are more than happy to help you understand the material more deeply, or to help you find flaws in reasoning that you have already done, but we're not here to do the work for you.

ewmon Posted September 4, 2012 Share Posted September 4, 2012 And why do you think the answer to #1 is c? 1. Which of the followingstatements about polypeptides is not correct? Answer their structure is influenced by hydrophobic effects they are synthesized inside the endoplasmic reticulum they can recognize specific DNA sequences their function can be modified by phosphorylation they can fold to form helices, sheets, coils 2. Which of the followingis not true of ribosomes? Answer they have codons in ribosomal RNA ribosomes catalyze peptide bond formation ribosome structure requires rRNA binding to proteins they can bind to transfer RNA they can bind to the 5' end of messenger RNA 3. The cell membrane formsas a result of Answer cholesterol binding covalent bonds between head groups hydrogen bonding between fatty acid chains hydrophobic effects on phospholipids assembly directed by membrane proteins 4. Which statement aboutcarbohydrates is incorrect? Answer can be attached to proteins can mediate selective transport into the cell can be used to store energy can be attached to lipids can provide structure for cells 5. Which of the followingstatements about electron transport used for respiration in animal cellsis incorrect? Answer produces CO2 involves proton transport consumes oxygen all answers are correct initiated by oxidation of NADH 6. Which of the followingis not true of DNA? Answer it is usually found as two anti-parallel strands it is located in the nucleus it is a template for synthesis of messenger RNA it is a template for the synthesis of DNA its nucleotide base-pairing is mediated by phosphodiester bonds 7. ATP Answer is an essential enzyme acts as an electron carrier base-pairs with thymidine nucleotides contains high energy bonds all answers are correct 8. A mutation in thenon-coding region of a gene Answer can change the expression of the gene product can change the structure of the gene product can't have a phenotype can't be inherited 9. A gene Answer is a trait is expressed only in the presence of RNA polymerases is assembled from a set of essential amino acids is replicated during the G1 phase of the cell cycle changes its information depending on the environment of the cell 10. Alleles of a gene Answer have the same DNA sequence can produce different versions of a protein mark the start and stop of transcription are always in the same DNA molecule 1 Link to comment Share on other sites More sharing options...
