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.

snow_tiger [21]

Answer:

Patrick's hypothesis was "If fish eat microwaved food, then they will swim faster through the maze."

The fish that are in the control group are the fish without microwaved food.

The independent variable is the microwaved food.

The dependent variable was the time it took for the fish to swim through the maze.

Patrick's conclusion should be that the special food did not seem to make a large difference in helping the fish become faster, since 8 out of 10 fish were faster in both special food and regular food groups.
