Question

During dna replication, the two strands separate as the ____________ bonds connecting the parent strands are broken by an enzyme called ____________ .

Answer 1

During DNA replication, the two strands separate as the hydrogen bonds connecting the parent strands are broken by an enzyme called helicase.

Step-by-step explanation:

During DNA replication, the two strands separate as the hydrogen bonds connecting the parent strands are broken by an enzyme called helicase.

1. DNA replication is the cycle by which a cell creates an indistinguishable duplicate of its DNA. It is pivotal for cell division and the transmission of hereditary data.

2. The DNA molecule has two complementary strands that are held together by hydrogen bonds that are formed between their nitrogenous bases.

3. To start DNA replication, the hydrogen connections between the nitrogenous bases of the parent strands should be broken, permitting the strands to isolate.

4. This detachment is worked with by a protein called helicase. Helicase loosens up the DNA twofold helix by breaking the hydrogen connections between the base matches, making a replication fork.

5. Each parent strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules once the strands are separated.

Answer 2

During DNA replication, the two strands separate as the hydrogen bonds connecting the parent strands are broken by an enzyme called helicase. In the DNA molecule (double strand) complementary bases are joined by hydrogen bonds; that is; Adenine paired to thyamine and guanine to cytosine; during replication the enzyme helicase separates the double helix by breaking the hydrogen bonds between the complementary bases.
