Speciation is the process by which new and distinct species are formed. One of the most important factors necessary for speciation to occur is the genetic isolation of two populations. This genetic isolation can, over long periods of time, cause these two groups to become genetically incompatible. Factors that can lead to this genetic isolation include geographic separation and hostility among population groups.

Which organic molecule is correctly paired with an end product of its break down via hydrolysis?
Gnoma [55]

Answer:

protein - amino acid

Explanation:

Proteins are one of the four major biomolecules in nature. Proteins are polymers of monomeric units called AMINO ACIDS. Amino acids are joined together by a type of covalent bond called PEPTIDE BOND to form proteins. Hence, since proteins are made up of amino acids, the hydrolysis of proteins will result in amino acids.

Hydrolysis is the breaking down of a large polymer into its monomeric unit with the release of water (H2O) molecule as a product. The bonds that forms between the respective amino acids are broken, hence, releasing the amino acids.

The reason that there are Okazaki fragments during DNA replication is ultimately because:
rusak2 [61]

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
