A. The size of the gene

B.The protein the gene will give rise to after translation

C.The nucleotide sequence (DNA or mRNA)

D.Spontaneous chemical changes

E. The location of the gene on the chromosome

(What is the correct answer)

2.Trinucleotides are really just:

A. A codon that will be read and converted into a single amino acid in a protein sequence

B.A piece of DNA that has no determined function, like an intron

C. Bits of DNA left over after transcription

D. Cellular waste product

3.Choose all the ways that a chemical can cause a genetic mutation.

A.It can cause a nucleotide substitution

B.It can cause RNA to fold around DNA

C. It can cause errant numbers of nucleotides to be added in DNA

D. It can cause structural changes in DNA that lead to mutation

E. It can cause DNA be degraded

F. It can cause RNA to be degraded

(A short answer)

4.What is a base analog and how does it confer a mutation into the new daughter DNA strand?

Answer 1

(1) Option no D is correct

The rate of mutation increases when you expose your body to harmful chemicals, radiation, buildup of free radicals or inadequate nutrients.

(2)

(3) option D is correct
