Which of the following could be the number of nucleotides in the DNA that codes for this protein? Question 12 options: A) 3 B) 100 C) 300 D) 900 E) 1800 Save Question 13 (1 point) Question 13 Unsaved If cytosine makes up 22 % of the nucleotides in a sample of DNA from an organism, then adenine would make up what percent of the bases? Question 13 options: A) 22 B) 44 C) 28 D) 56 E) It cannot be determined from the information provided Save Question 14 (1 point) Question 14 Unsaved Which of the following is NOT related to ribosomal activity? Question 14 options: A) A site B) spliceosome C) codon recognition D) peptide bond formation E) P site Save Question 15 (1 point) Question 15 Unsaved The processing of the primary transcript involves Question 15 options: A) the removal of introns and the splicing together of exons B) the removal of exons and the splicing together of introns C) the addition of a guanine cap and a poly-A tail D) the attachment of introns to ribosomal RNA E) Both A and C are correct Save Question 16 (1 point) Question 16 Unsaved A frameshift mutation could result from Question 16 options: A) a base insertion only B) a base deletion only C) a base substitution only D) deletion of three consecutive bases E) either an addition or a deletion of a base Save Question 17 (1 point) Question 17 Unsaved A silent mutation can result from: Question 17 options: A) the insertion of a base pair B) the substitution of a base pair that results in the same amino acid C) the deletion of a base pair D) the substitution of a base pair which lies in an intron and is eventually spliced out by spliceosomes E) B and D Save Question 18 (1 point) Question 18 Unsaved mRNA Question 18 options: A) makes up the ribosomes in the cell B) carries the genetic information from the nucleus into the cytoplasm C) is helical D) is a double strand E) always codes for all 20 amino acids Title: Re: A possible sequence of nucleotides in the DNA that would code for the polypeptide sequence –Phen Post by: bio_man on Aug 19, 2015 All of these questions are highly doable! But you've written too many in one topic. To tackle the one below, divide the number of amino acids by 3 (three nucleotides define an amino acid).
A particular eukaryotic protein is 300 amino acids long. Which of the following could be the number of nucleotides in the DNA that codes for this protein? Question 12 options: A) 3 B) 100 C) 300 D) 900 E) 1800 100 |
