Answer: A bond in which electrons are shared.
The right answer is 5.
To answer this question it is sufficient to take the same approach as the one that concluded that each amino acid is equivalent to 3 codons.
We have 17 amino acids, each of which must have at least one unique code (having two nucleotides A and T)
.
it is enough to apply this time to count the number of possible codons to be generated according to the number of nucleotides:
nucleotide set ^ number of nucleotides = number of codons
.
2 ^ 1 = 2 (<17)
2 ^ 2 = 4 (<17)
2 ^ 3 = 8 (<17)
2 ^ 4 = 16 (<17)
2 ^ 5 = 32 (> 17)
So, each amino acid has a codon of 5 nucleotides.
The is answer is:
1. first to document careful observations of different cell types
