Answer:

DNA primers

Explanation:

PCR uses short DNA segments called as primers. These primers become paired with the template DNA strands and are being elongated by the DNA polymerase enzyme (Taq polymerase). On the other hand, in vivo DNA replication does not use the DNA primers. Primase is the enzyme that makes RNA primers with free 3' OH end which is then elongated by DNA polymerases. The RNA primers are synthesized when the primase enzyme makes a short RNA copy of the DNA template strand.

What are hydrogen bonds and how do they affect the physical characteristics of water?
Kobotan [32]

Explanation:

A hydrogen bond is a common type of chemical bond in organisms. As the name suggests, this type of bond involves a hydrogen atom. The hydrogen is attracted to a strongly electronegative atom, such as oxygen, fluorine, or nitrogen of a polar covalent bond in the same or another molecule.

This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
