Answer:
42
Explanation:
The mass number of an atom is equal to the number of protons plus the number of neutrons in a nucleus
This atom Mo-96 has an atomic number of 42 and so has 42 protons in the atom.
He demonstrated that SCD and sickle cell trait were due to the presence of abnormal 8-globin polypeptides in red blood cells. He demonstrated that the electrophhoretic mobility of B-globin from patients with SCD was different from that of healthy individuals. He demonstrated that both parents of multiple patients with SCD had low levels of sickled red blood cells. He hypothesized that SCD was a recessive trait and that the parents of patients with SCD would be heterozygous carriers. He demonstrated that the difference between B-globin polypeptides in individuals who were healthy and those with SCD is an amino acid substitution. He performed a peptide fingerprint analysis on B-globin from individuals with 84 84 and 89 88, which identified the segment of B-globin that was changed by the BS mutation.

answer: 2) sequence of building blocks of a protein found in a cell.
Just random FYI:
- it is a mutation, that is generally not looked upon as being severe or detrimental to the person
-by changing the base by either adding or deleting from a protein strand will cause the protein to be useless
-frameshift mutation deals with DNA sequence being shifted. For example: a DNA strand looks like a ladder. If one of the rungs on the ladders gets skipped and the next ladder rung gets the code that the previous rung should have gotten, then that is what a frameshift mutation is. Hopefully that makes sense. It's easier to explain if there was a picture.
there are other types of mutation but I won't get into them.
Hopefully this helped and good luck.
Most adult placental mammals have no remaining trace of the cloaca. Being placental animals, humans only have an embryonic cloaca, which is split up into separate tracts during the development of the urinary and reproductive organs.
