Answer:

Alveoli

Explanation:

  • Alveoli is the part of the respiratory system which forms the site for an exchange of gases.
  • The exchange is essential to release out carbon dioxide and take in oxygen.
  • Alveoli being the site of gaseous exchange should have the essential features of a good respiratory surface which are -<em> thin, moist and enriched with blood vessels.</em>
  • Due to this, the alveoli are made up of a single layer of epithelial cell and has a network of capillaries surrounding it that carry blood to facilitate the exchange the gases.

What significance do the bases AUG, or UGA have? hint use decoder chart needed. A. a. the first one is a start codon and the sec
Minchanka [31]

Answer:

The importance of the AUG and UGA bases lies in the fact that the first one is a start codon and the second one is a stop codon, respectively (option a).

Explanation:

Codons or triplets are sequences of three nitrogenous bases, in the mRNA, that determine the synthesis of a specific amino acid.

  • <em>AUG </em><em>is called the </em><em>initiation or start codon</em><em>, and is usually at the beginning of a peptide synthesis, in addition to encoding the amino acid methionine. </em>
  • <em>UGA</em><em> is a</em><em> termination or stop codon</em><em> found at the end of a petid chain when it is complete.  UAA and UAG codons are also STOP or termination codons and, together with UGA, do not code for amino acids.</em>

The biological importance of start and stop codons is to initiate the synthesis of a protein and to stop the addition of amino acids when their size is adequate.
