If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?a. Insertion
b. Substitution
c. Translocation
d. Deletion

Answers

The answer is d. deletion.

If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.

The relative concentration of water in a hypotonic solution is _____.high
low
equal
stable

Answers

Answer: The correct answer for the fill in the blank is High.

Hypotonic solution is the one, which contains less concentration of solute (like salt)  as compared to the solvent (water).

In other words, in a hypotonic solution, the concentration of solvent is higher than the concentration of solutes.

Thus, the relative concentration of water ( which is a solvent) in a hypotonic solution is high.

The relative concentration of water in a hypotonic solution ishigh. The correct answer between all the choices given is the firstchoice. I am hoping that this answer has satisfied your query about and it willbe able to help you.
