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.

Patterns of ____ indicate how age at death influences population size:a. death rate
b. age structure --b is not it I know that
c. survivorship
d. logistic growth

Answers

The answer is letter A.

Death rate refers to the measure of the number of deaths in a particular population. It is scaled to the size of the population per unit of time. Which generally includes death from specific age groups and causes. It is typically expressed in units of death per 1,000 individuals in a year. It could also indicate how age at death influences population size or otherwise known as “morbidity or mortality rate.” The unit may also change if certain diseases are taken into consideration for the count.

Patterns of __C_____ indicate how age at death influences population size.
