Infant suckling

<span>Infant suckling is the stimulus that is needed for continued and sustained production of breast milk. When an infant suckles, stimuli are transmitted to the mother's pituitary gland and prolactin (a hormone responsible for milk production) is released by the pituitary and this leads to the production of more milk. The more an infant suckles, the higher the prolactin level and the amount of milk produced.</span>

#9 I need help please
kondor19780726 [428]

Answer:

500 amino acids

500 codons

Yes

Explanation:

A codon is a set of 3 base pairs. Each codon codes for a specific amino acid. So the ratio between codon and amino acid is 1:1 and the ratio between base pairs and codon is 3:1.

If you have 1,500 base pairs then we can mathematically solve the number of codons:

\dfrac{1,500}{x} = \dfrac{3}{1}\\\\(1,500)(1) = (3)(x)\\\\\dfrac{1,500}{3} = x\\\\ 500=x

Since the ratio of codon to amino acid is 1:1, then for every 500 codons, there are 500 amino acids.

I hope this helps clear it up a bit for you.
