Question

Select all the correct answers.


This sequence encodes for a particular protein that helps bacteria move. A mutation occurs in the sequence, leading to a faulty protein. Identify the sequences where the mutation might have taken place.

( ) = RED

ATTTGC(ATACTACC)GGGC


The red letters are the noncoding region, and the black letters are the protein coding region.


answers are-


1. ATTAGC(ATACTAC)GGGC


2. ATTTGC(ATACTGACC)GGGC


3. ATTTGC(AATACTACC)GGGC


4. ATTTGC(AACTACC)GGGC


5. ATGAATGC(ATACTACC)GGGC

Answer 1

The correct answers choices would be 1. and 5.

Both of these show mutations outside the red zone.

Answer 2

Answer:

1.  ATTAGC(ATACTAC)GGGC

5. ATGAATGC(ATACTACC)GGGC

Explanation:

Since the sequence in "red" specifies the non-coding region, any change in it would not affect the protein structure or function. Only the sequences that have mutation in "black letters" would affect the protein structure and function.  

Among the given options, options 1 and 5 have mutations in the protein coding region of the sequence. So, these sequences could lead to production of faulty protein.
