The answer is helicase. These are a class of enzymes important to all living organisms. Their chief purpose is to unzip an organism's genes. They are motor proteins that travel directionally alongside a nucleic acid phosphodiester backbone, unravelling two annealed nucleic acid using energy consequential from ATP hydrolysis.

nekit [7.7K]

Answer;

Mesoderm

The mesoderm is a layer of the embryo, which will become the circulatory system, bones, muscles, excretory system, and reproductive system.

Explanation;

-The germ layers develop early in embryonic life, through the process of gastrulation. An inner layer, called endoderm, and an outer layer, called ectoderm and a middle layer called mesoderm.

-The embryonic endoderm develops into the interior linings of two tubes in the body, the digestive and respiratory tube. the lining of the follicles of the thyroid gland and the epithelial component of the thymus.

-Ectoderm develops into parts of the skin, the brain and the nervous system. Mesoderm gives rise to bones, muscles, the heart and circulatory system, and internal sex organs.

Is race a biological characteristic determined by our genes?
Harman [31]

Answer:

No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.
