Question

A gene has four exons with lengths in base pairs (bp) as follows.

Exon 1, transcription start to just before ATG translation initiation codon:      219 bp

Exon 1, from ATG initiation codon to end of segment:                                        282 bp

Exon 2, all:                                                                                                          201 bp

Exon 3, all:                                                                                                             93 bp

Exon 4, beginning through (and including) TGA stop codon:                          177 bp

Exon 4, from just after TGA stop codon to polyadenylation site:                        405 bp

Question: How many amino acids does the protein contain?

A. 324 amino acids

B. 969 amino acids

C. 459 amino acids

D. 386 amino acids

E. 323 amino acids

F. 1158 amino acids

G. 1377 amino acids

H. 753 amino acids

I. 251 amino acids

J. 250 amino acids

K. 972 amino acids

L. 750 amino acids

Explanation / Answer

h:753 amno acids as its starts from ATG initiation codon before that it will not be a part of the protein and stops at TGA stop codon. after that it ill not be coded
