Ans.

The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.

The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.

The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.

The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).

Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.

"Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis"
Reika [66]

Answer:

Explanation:

The electron-carrier proteins are arranged in the inner mitochondrial wall. A dehydrogenase enzyme (think of it as the first protein of the electron-transport chain) oxidises NADH2 (which is the reduced coenzyme NAD) and/or FADH2 (reduced coenzyme FAD). The energy from the oxidation process is used to pump hydrogen ions from the matrix to the inter-membrane space of the mitochondrion. Because of this, gradient of hydrogen ion concentration builds up across the inner mitochondrial membrane, which generates a potential difference across the membrane. The protons then flow back to the matrix through an enzyme called ATP synthase (also called ATPase). (This is called chemiosmosis because a chemical substance (H+) moves across a membrane, down the concentration gradient.) This releases energy needed for the ATP synthase to phosphorylate ADP, i.e. make ATP (chemical energy for use in the cell) from ADP and inorganic phosphate.

Note: Bolded things are important, everything else is just additional clarification in case you need it. This is the last major phase of cellular respiration. If you want a deeper insight into the process, I suggest you read a bit about glycolysis and Krebs cycle.

Which components are identical in all amino acids?
yKpoI14uk [10]

The correct option is (D).

An amino group and carboxylic acid group are the most basic common components in all amino acids. While, R group in the amino acids always different (here R describes the alkyl group).

Organic substances having both amino and carboxylic acid functional groups are known as Amino acids. Alpha-amino acids, which make up proteins, are by far the most significant of the hundreds of amino acids found in nature.

Amino acids perform a variety of processes in our body including muscular growth, delivering nutrition, prevent disease, and many more. A lack of certain amino acids can lead to a variety of health concerns, including lowered immunity, digestive disorders, depression, less mental alertness, slower child growth, etc.

There are total 20 amino acids, out of them 9 are essential amino acids means they are not synthesis by our body they must be taken outside from diet and nutrition.

If an increase in blood flow to an organ results in stretch of a vessel, it [the blood vessel] will respond reflexively by vasoc
djverab [1.8K]

Answer: false

Explanation:

The vessel will respond reflexively by stretching indicating vasodilation and also allowing an increase in the the blood flow to the vessel, in contrast to vasoconstriction which causes narrowing and decreased blood flow to the organ.
