The concentration of PSA (prostate-specific antigen) in the blood is sometimes used as a screening test for possible prostate ca

ncer in men. The value is normally reported as the number of nanograms of PSA per milliliter of blood. A PSA of 1.6 ng/mL is considered low. Express that value in terms of the units shown.

Maksim231197 [3]

The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.

Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding
Nana76 [90]

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.
