vlada-n [284]

Answer:

DNA is copied and transcribed into another form. This smaller segment is made of <em><u>genes.</u></em>

Explanation:

Cell growth, replication, and cell repair are controlled by genetic material found within DNA molecules. These deoxyribonucleic acids' long-chain helical macromolecules are assembled from complex sequences called nucleotides; strong covalent bonds attach these four monomers (adenine, cytosine, guanine, thymine).

Coding regions of DNA are called genes- they contain specific instructions for the cell. Genes can include multiple nucleotides and even several chromosomes. Gene expression typically includes transcription into RNA, and translation into amino acids/ proteins.

Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.

The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.

Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.
