Answer:

From left to right across a period.

Explanation:

The least amount of energy needed to withdraw the valence electron is known as the ionization energy. The alkaline metals exhibit lowest ionization energy and are removed easily, as they possess one valence electron, these metals are present in far left in the main group. Right next to alkaline metals, that is, the alkaline earth metals exhibit higher ionization energy in comparison to alkaline metals, as they exhibit two valence electrons. The nonmetals are present far right in the main group and they exhibit the highest ionization energy, as they possess numerous valence electrons.

Alex

Answer:

a) Yes

b) Yes

c) Yes

d) Yes

Explanation:

a. In the exons?

Yes mutant site will be expected. It will transcript-ed as well and it can be a polypeptide depending on the mutation type.

b. In the intron?

Yes mutant site will be expected. It will be transcript-ed as well and it cannot be a polypeptide

c. In the promoter?

Yes mutant site will be expected. It will not be transcript-ed and it cannot be a polypeptide

d. In the intron-exon boundary?

Yes mutant site will be expected. It will be transcript-ed and it cannot be a polypeptide
