Question

plz answer my question with solution !!!​

Answer 1

Answer:

Option (3)

Explanation:

Frame shift mutation occurs when certain bases are deleted or inserted in such a manner that it affects sequencing of the genetic codons that were originally in the genome.

In this question,

• In option (1), 'C' is substituted with 'G'; It is substitution mutation
• In option (2), the sequence is just a mRNA transcript of the given sequence
• In option (3), A new base 'G' is introduced at 4th position, Hence it's frame shift mutation. Here, it affected the genetic codon following it.
• In option (4), 'A' is substituted with 'T'
