1. The enzyme DNA helicase breaks the hydrogen bonds between bases on the two polynucleotide DNA strands. This makes the helix unwind to form two single strands.
2. Each original strand acts as a template for a new one. Complementary base pairing means that free DNA are attracted to their complimentary exposed bases on each original template strand; A with T; C with G.
3. The enzyme DNA polymerase joins the nucleotides of the new strand together via condensation reactions. Hydrogen bonds form between the bases on the original and new strands
Answer:
Due to number of amino acids.
Explanation:
The main differences might be expected in the amino acid composition of X versus Y because the X polypeptide is made up of one smaller unit of amino acid while on the other hand, Y polypeptide is made up of four smaller units of amino acids. The name of X is monomer which means composed of one amino acids while Y exists as a tetramer which means it has four amino acids. So we can conclude that the main difference between X and Y is the presence of number of amino acids.
If someone has blood type A, they must have atleast one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. while an individual with blood type B will have a genotype of either BB or BO. Individuals with type O blood will have a genotype OO. Both A and B alleles are dominant over O.
Therefore, the genotype of the man is AO, that of the mother is BO, while that of the child is OO.
In future from this marriage, the possible genotypes are;
AO, BO, AB, or OO
In the frequency of 1/4 each.
Answer:
They help digest food, make vitamins, and play other important roles. Humans also use bacteria in many other ways, including: Creating products, such as ethanol and enzymes. Making drugs, such as antibiotics and vaccines.
The answer is White
Hope this helps :)
