. The original DNA sequence below has undergone 16 substitution mutations. In the spaces below, write the letters of the original bases that have been replaced. Write the letters in the order in which they occur from left to right. Your work will reveal the answer to the question below. original sequence:

Explanation:

A change in one base of the gene sequence is known as point mutation.

Explanation:

Question 2 is incomplete.

3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.

In Point mutations there is substitution of one base for another.

Example:                TAT TGG CTA            

                              TAC TGG CTA

The  TAT changes to TAC which shows point mutation.

4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.

When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.

This is an example of 'niche differentiation'. In ecology, this is when competing species use the environment differently in a way that reduced their direct competition. In the example given above, the different species of salamander choose different sizes of prey items to avoid competition. Other strategies may be to occupy different micro-habitats within a shared larger habitat, such as in a forest, competing species may avoid competition by one occupying the forest floor whereas another may occupy the canopy layer.
