That’s the only one I know but sorry
ionic bonding.
Ionic bonding<span> is a type of </span>chemical bond<span> that involves the </span>electrostatic attraction<span> between oppositely charged </span>ions<span>, and is the primary interaction occurring in </span>ionic compounds<span>. The ions are atoms that have gained one or more </span>electrons<span> (known as </span>anions<span>, which are negatively charged) and atoms that have lost one or more electrons (known as </span>cations<span>, which are positively charged). This transfer of electrons is known as </span>electrovalence<span> in contrast to </span>covalence<span>. In the simplest case, the cation is a </span>metal<span> atom and the anion is a </span>nonmetal<span> atom, but these ions can be of a more complex nature, e.g. molecular ions like NH</span>4+<span> or SO</span>42−<span>. In simpler words, an ionic bond is the transfer of electrons from a </span>metal<span> to a </span>non-metal<span> in order to obtain a full valence shell for both atoms.</span>

E. Starting at the most basic level is the atom
Answer:
D) can allow the production of different proteins from a single gene.
Explanation:
Alternative splicing:
Alternate splicing is also known as alternative RNA splicing, or differential splicing. Alternate splicing is a regulated process during gene expression in which multiple proteins are produced from single gene.
Actually eukaryotic genes have both Intron and exon sequences. Exons are the sequences present inside mRNA which convert into amino acids and produces peptides while introns are the sequences which are spliced (cut) from pre mRNA.
Some time introns for some proteins becomes exons for other proteins in this ways one gene can produce multiple proteins.
