Enzymes bind with chemical reactants called substrates
The answer is false.
Deamination is the process (reaction) in which an amine group is removed from a molecule of amino acid. The enzymes that are involved in this reaction are called deaminases. Deamination can be used for energy(break down of amino acids), when there is too much protein intake. Amine group is converted to ammonia that is then converted to urea or uric acid in the urea cycle and at the end excreted through the urine.
In the human body, deamination occurs mostly in the liver (e.g. urea cycle), but also in the kidneys (deamination of glutamate).
Answer:
Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.
The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
Since one of the dogs is a heterozygous dog, it means that the dog isn’t completely have black fur. Yes, the dog has the gene, but he also has the recessive gene of yellow fur. Making his yellow fur gene be recessive and get covered by the black fur dominant gene. (Bb). With the other parent has pure yellow fur recessive gene (bb). The punnet square below explains more clearly what I mean.
This means that there is a 50/50 chance of getting some puppies with full yellow fur but there is another 50/50 chance of then having the dominant gene of black fur but still having the yellow fur gene hidden.
