2. use the chart above to determine which substitution mutation has the potential to cause more damage? highlight your answer. (2pts)

a. substitution of 3rd n-base to go from cau to cac

b. substitution of 3rd n-base to go from ugu to ugc

c. substitution of 3rd n-base to go from ucu to uuu

3. explain why: (

4. explain what a stop codon is and why it is important. (5 points)

Answer No 2:

The correct option is C. Substitution of 3rd N-base to go from UCU TO UUU has the potential to cause more damage.

Answer No 3:

UCU codes for the amino acid serine whereas the code UUU is for phenylalanine. A change in this base has caused the entire amino acid to change which will result in the formation of the wrong protein.

Whereas the changes in the base sequence of the options A and B do not change the amino aids being made. Hence, the changes in options A ans B will be less damaging then the option C.

Answer 4:

In the field of genetics, a stop codon can be described as a signal which stops the translation. It is a three nucleotide sequence which is recognized as a terminator.

If stop codon is not present at the right place, then the process of translation will not terminate at the right place and wrong proteins will be made.

where is the option.let me know
