Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
Answer:
a. Ligase
b. Ligase (

Explanation:
DNA synthesis begins, therefore, by synthesizing a short segment of RNA called a primer, which primer is synthesized by an enzyme called Primasa. Primasa is an RNA polymerase that uses DNA as a template. All fragments of Okazaki begin with a Primer. Subsequently, the DNA polymerase III Holoenzyme performs the synthesis of the corresponding DNA fragment until it reaches the next primer. At that time, DNA polymerase Ia replaces the DNA polymerase Holoenzyme III. The DNA polymerase I is responsible for removing the RNA primer through its 5'P-3'OH exonueotic activity and at the same time fills the hole by synthesizing DNA.
Finally, the two Okazaki fragments have to be joined, it is necessary to link the 3'OH end of a fragment with the 5'P of the next fragment. This work of sealing and joining the successive fragments is done by Ligase.

<span>The answer is a sexual reproduction. This is due to the formation
of gametes that enable the variation of the offspring of the parents. Firstly,
each gamete contributes half the genetic material (alleles)from either parent.
The dominant alleles will show in the phenotype of the c=ofspirng. Additionally,
during meiosis (the process that makes gametes), recombination of genetic
material can occur hence transferring unique combination of genes from that of
the parent. Therefore, there are many possible combinations of gametes that
gives the offspring variance from the parents</span>
