Exploring DNA Replication and Inheritance

The video explains the process of DNA replication, starting with the unwinding and separation of the double-stranded DNA. Each strand serves as a template for the formation of a new complementary strand, following the base pairing rules where adenine pairs with thymine and guanine pairs with cytosine. This results in two identical DNA double helices, each consisting of one old and one new strand.

What is the first step in the process of DNA replication?

• The double strand of DNA unwinds and the strands separate.

• The bases pair with free-floating bases in the cell.

• The DNA double helix forms a new complementary strand.

• The cell divides.

During DNA replication, which base pairs with Adenine (A)?

• Thymine (T)

• Guanine (G)

• Cytosine (C)

• Uracil (U)

Which of the following is NOT a correct base pairing rule?

• A pairs with G

• T pairs with A

• G pairs with C

• A pairs with T

What role do the unwound DNA strands play in replication?

• They form RNA strands.

• They dissolve in the cell.

• They combine with other DNA strands.

• They act as templates for the formation of new complementary strands.

What is the result of DNA replication?

• One new DNA double helix and one old single strand.

• Four new DNA strands.

• Two DNA double helices, each with one old and one new strand.

• Two identical RNA strands.
