Answer:

Explanation:

A testable question is the one which can be answered using experiment and research. A non-testable question is the one which cannot be answered using experimental trials.

Example:

Non-testable: Which is more better ice-cream or chips?

Testable: Which is more better nutritionally ice-cream or chips?

Here, in the non-testable question no parameter was given for comparision and analysis hence, it cannot be tested experimentally. Whereas, in the testable question nutritional quality is to be compared between the two food items.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Zinaida [17]

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
