B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.
C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.
D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.
The answer is A
Explanation:
In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.
Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).
On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.
Answer: It proposes that the entire double‑stranded DNA molecule serves as a template for a whole new molecule of DNA.
Explanation:
In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand serves as template, and then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand for both
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent double strand is retained in the newly synthesized DNA, this model is described as semi-conservative
