<h2>ANSWER:</h2>

Ribosomes

<h2>EXPLANATION:</h2>

Ribosomes consist of a couple important elements: the small ribosomal subunits, which read the RNA, and the large subunits, which associate amino acids to develop a polypeptide chain. Every subunit contains one or more ribosomal RNA (rRNA) molecules and a diversity of ribosomal proteins

Molodets [167]

Answer:

Heredity

Explanation:

This is because heredity is the sum all biological processes and it is the process where traits or characteristics are inherited or passed down to offsprings from their parents. It refers to sum of all traits that the offsprings have inherited from their parents and these make the offspring to have resemblance of the parent

The nucleotide sequence of a DNA codon is TAG. In an mRNA molecule transcribed from this DNA, the codon has the sequence _______
inna [77]

Answer:

The nucleotide sequence of a DNA codon is TAG. In an mRNA molecule transcribed from this DNA, the codon has the sequence 5'-<u>AUC-3'</u>. In the process of protein synthesis, a transfer RNA pairs with the mRNA codon. The nucleotide sequence of the tRNA anticodon is <u>3'-UAG-5'</u>. The amino acid attached to the tRNA is <u>Isoleucine</u>.

Explanation:

In the process of protein synthesis the mRNA contains the sequence of nucleotides —transcribed from the DNA— that defines the sequence of amino acids that a synthesized protein will have.

Codons are triplets of nitrogenous bases present in mRNA, which encode an amino acid, as well as the start and end of protein synthesis.

Anticodons correspond to triplets of bases present in transfer RNA (tRNA), which correspond with mRNA codons. tRNA is responsible for coupling amino acids to the polypeptide chain being synthesized. In view of this:

<em>- DNA triplet:               TAG</em>

<em>- Codon mRNA:      5'-AUC-3' </em>

<em>- Anticodon tRNA:   3'-UAG-5'</em>

<em>- Amino acid:           Isoleucine</em>

A callus is a hardening of skin, which protein is very abundant here?
Pie

Answer:

A callus is a hardening of skin, keratin is the protein which is abundant in callus. Skin is a protective layer against a external environment. Outer layer of skin consist of keratin which is also found in hair. Callus is the accumulation of dead cells result due to friction and pressure exerts on the part in which they are present. The keratin component (keratinocytes) remains undifferentiated in these dead cells which causes hardening in callus.
