Why are certain amino acids called essential amino acids?

2 answers:

7 0

Essential amino acids refer to the eight amino acids the adult body needs, which they cannot be synthesized correctly or at all.
The essential amino acids must be obtained from food such as proteins (meats, seafood, milk, eggs, etc).

BCAAs are considered essential because, unlike non-essential amino acids, your body cannot make them. Therefore, it is essential to get them from your diet. Bottom Line: The three BCAAs are leucine, isoleucine and valine. All have a branched molecular structure and are considered essential to the human body.

If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein forme

erastovalidia [21]

Answer:

See the answer below

Explanation:

An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.

Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons.

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

Lynna [10]

Answer:

Explanation:

1- the purpose of blood flow-circulatory system- is to convey Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries and capillaries away from the heart, to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.

2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied through the bicuspid valve into the Left.Ventricle.

During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.

Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is forced through the aortic valve to empty into the aorta into the systemic circulation,branches of the carotid artery supplies the heart from the aorta.

The Whole cycle continues.
