Question

Suppose an error in transcription causes threonine (Thr) to be incorporated into the variable region of an antibody instead of arginine (Arg). Which of these could describe the error?
ACG was transcribed instead of AGC.
ACC was transcribed instead of ACA.
AGA was transcribed instead of AGG.
ACA was transcribed instead of AGA.

Answer 1

Answer is: ACA was transcribed instead of AGA.Codons for threonine are: ACT, ACC, ACA, ACG.
Codons for arginine are: CGT, CGC, CGA, CGG, AGA, AGG.
The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells.
