Answer:
246 amino bases
Explanation:
An amino acid is coded by three bases. However, in a DNA molecule, there is coding that takes place. In DNA replication, the start and stop codons are not expressed during the formation of the double helix. Hence, an extra amino acid will be needed. In fact, this can be expressed mathematically like this:
where n is the number of amino acid residues. Therefore, taking 81 amino acid residues yields:
N =
Therefore, the least number of bases needed will be 246
The reaction of 1-bromo-2-methylpropane (isobutyl bromide), , with
, and
results in the formation of an adduct of formula
known as grignard reagent, an organometallic reagent, which on reacting with
results in the formation of isobutane.
The reaction is shown in the image.
