Answer:

<u>Functions of epithelial tissue:</u>

  • i. Epithelial tissue covers the body outside and lines the various cavities inside.
  • ii. Epithelial tissue lines the hollow organs, body cavities, blood vessels and ducts.
  • iii. Cells are rested on thin, doubled layered, non-cellular basement membrane.
  • iv. Epithelial tissue has nerve supply of its own.
  • v. Epithelial tissue is avascular (a = without, vascular = vessel), i.e. it lacks its own blood supply and hence, obtains nutrients which diffuse out of blood vessels.
  • vi. Epithelial tissue has the power of division and regeneration. The old injured dead cells are sloughed off regularly and are replaced by new ones.

dmitriy555 [2]

Take the place of part of an mRNA within the ribosome.

Rna triplets

The nucleotide sequence copy of a gene is present in the mRNA. Each amino acid is represented by a triplet of the four nucleotide bases that make up the genetic alphabet. The relationship between triplet sequences and amino acids is known as the genetic code.

A codon is a triplet of RNA nucleotides that codes for a particular amino acid. To the ribosome, where translation takes place, the tRNA transports certain amino acids. During translation, the anticodons in the tRNA bind to the codons in the mRNA templates. It is essential for the codon and anticodon to interact in order to pair the codon with the appropriate amino acid.

In mRNA, each trio of nucleotides is referred to as a codon, and each codon designates a certain amino acid (hence, it is a triplet code).
