What is a change in the DNA nucleotide sequence called? a. an anti-codon b. translation c. tRNA d. transformation e. mutation 14. What types of genetic information are encoded by DNA? a. order of amino acids in a protein b. when a specific protein is made c. how much of a protein is made d. just proteins e. when a specific protein is made, order of amino acids in a protein, and how much protein is made 15. What determines how proteins fold into their three-dimensional shape? order of amino acids a. b. order of DNA base-pairing c. cytoplasmic water levels d. e. number of genes in the DNA how many receptors are present on the cell surface 16. If all 18 nucleotides in a particular sequence are translated, how many amino acids would be in the polypeptide? a. 2 b. 3 c. 4 d. 5 e. 17. The process of transcription requires a. transfer RNA b. DNA c. messenger RNA d. DNA polymerase e. all of theseExplanation / Answer
12. Correct answer:- (e) by Changing both the amino acid sequence and the mRNA transcript.
Explanation- mutation is the permanent alteration of the nucleotide sequence of the genome of an organism.
- it causes chanege in mRNA transcript and amino acid sequence.
13. Correct answer:- (e) mutation
Explanation:- mutation is the permanent alteration of the nucleotide sequence of the genome of an organism.
14. Correct answer:- (e) when a specific protein is made, order of amino acid in a protein and how much protein is made.
Explanation- DNA encode regulation of protein formation.
15. Correct answer:- (b) order of DNA base pairing
Explanation:- chemical bond formation occurs between the nitrogenous base and three dimensional shape is formed.
16. Correct answer:- (e) 6
Explanation:- A codon is a triplet.
17. Correct answer:- (e) all of these
Explanation- transcription is the formation of mRNA from DNA molecules.
- transcription Require- DNA polymerase, mRNA, tRNA.
