Explanation / Answer

Ans 50...e...during transcription from DNA to rna

A convert to U

T convert to A

C to G

G to C

So correct sequence would be UUCGAG

Ans 51...ans is d...2

3 nucleotide form 1 codon and then from 1 codon 1 amino acids is formed so 6 will form 2 codon and thus 2 amino acids.

Ans 52...again by using the rule of complimentry...the 2nd codon given is CTC so the complementry will be GUG.so the right ans is

A...GUG

Ans 53...In DNA compliment everything is as same as explained in ques no. 1 except

A is complimentary to T here and not to U in DNA so ans will be

d...TTCGAG
