Siamese cats most of the time mate with Aegean cats, and the reason why is because Aegean cats are also domesticated and most of the times can easily be found.
Beacuse they have the same dna and they came from the same organism so one of them is a dna organism that does something and the other is not unless if it has the same dna
The first stage of gene expression is the transcription step, ie the passage from ADn to mRNA, the RNA polymerase will read DNA (the TAC sequence) and will synthesize a complementary strand (AUG) in the form of mRNA (which will then undergo mRNA processing).
The second stage of gene expression is the translation of mRNA into protein: the AUG sequence of mRNA (supposed to be the start codon) is translated to the amino acid, methionine, via the ribosome and tRNA. The ribisome will read adjacent codons to form the polypeptide (several amino acids bonded together by peptide bonds).
What is Sickle cell anemia?
Sickle cell is an autosomal recessive trait of humans that arises through mutation in normal gene. The gene for this trait is found in recessive form and you need two copies of the gene - one from father and one from mother- to have the trait expressed. If the trait is expressed it causes a disease called sickle cell anemia.
People with the sickle cell anemia disease have red blood cells of crescent or sickle shape. The red blood cells of this shape can cause many complications in body. They get stuck in blood vessels and cause pain. They also die quickly and make a person anemic (pale).
Probability to have a child with sickle cell anemia:
If a mother is normal but a father is carrier for the trait, then the situation will be as:
Here N indicate normal allele, S indicate allele for sickle cell anemia.
Mother ˣ Father
NN NS
Gametes: N N N S
Offspring: NN NS NN NS
50% : Normal
50% : Carrier
0% : Sickle cell anemia
It means that 50 % kids will be normal and 50% will be carrier for the trait and none of the offspring will have disease Sickle cell anemia.
However, those who are carriers can carry the disease to the next offspring if they are married to a carrier or a person with sickle cell anemia.
