If the pedigree you are referring to is the one that is attached then the answer would be:
A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.
All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.
The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.
<span>The interactions
between the mRNA codons and the tRNA anticodons
codes for a specific amino acid is by, it is the job of the tRNA to
start working after the mRNA has able to have its own complementary copy. The
mRNA will undergo to the nucleus and will move out, in order to go the rrna.
The three nucleotides codes the specific amino acid of the trna. The trna and
the mrna will be matched, it will now release the amino acid in the trna that
wil form a peptide bond. When the mrna is able to be decoded to form an amino
acid, it will now have the ability to break and make proteins in different
structures.</span>
