Most viruses have<span> either </span>RNA<span> or </span>DNA<span> as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious </span>virus<span> particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest </span>viruses contain<span> only enough </span>RNA<span> or </span>DNA<span> to encode four proteins.</span>

By definition, C. Crossing over only occurs in meiosis that does not happen in mitosis.

In humans, new neurons are continually born
throughout adulthood in two regions of the brain:
<span>·
</span><span>The subgranular
zone (SGZ), part of the dentate gyrus of
the hippocampus.</span>
<span>·
</span><span>The striatum;
however the adult-born neurons are a type of interneuron,
not a type that projects to other brain areas.</span>[5]
<span>In other species of mammals, particularly rodents,
adult-born neurons also appear in the olfactory
bulb. In humans, however, few if any olfactory bulb neurons are
generated after birth.</span>
