The regulation of gene expression conserves energy and space. It would require a significant amount of energy for an organism to express every gene at all times, so it is more energy efficient to turn on the genes only when they are required.

If two organisms show a developmental homology you would also definently expect them to?
san4es73 [151]

If two organisms show a developmental homology you would also definitely expect them to share genetic homologies.

Homology is the similarity between two organisms. This similarity can be of body structures, physiology, etc. This homology is generally due to shared ancestral history between two organisms. For example, the wings of a bird and bats are homologous structures, this is because they have a common anatomy.

Genetic homology refers to the arrival from the same gene from a common ancestor. The same gene is shared between two organisms who may not be related in any other matter. Genetic homology can even be depicted by the sequences of a protein.

AfilCa [17]

Answer:

<h2> AA </h2>

Explanation:

1. A restriction enzyme, restriction endonuclease, an enzyme that cleaves DNA into small fragments at or near specific recognition sites (different  restriction enzyme has different restriction site) within molecules known as restriction sites.

2. Restriction enzymes are found in archaea and bacteria.

3 And in  bacteria and archaea they provide a defence mechanism against invading viruses.

4. Each restriction enzyme cut at the specific site, because each restriction enzyme have specific recognition site.
