What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix, separating the two strands to allow for replication.

Front

Which nitrogenous base pairs with guanine in DNA?

Back

Cytosine pairs with guanine in DNA.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand during DNA replication.

Front

Given the DNA strand ATG TGA CAG, what is the complementary strand?

Back

The complementary strand is TAC ACT GTC.

Front

What is deoxyribose sugar and its role in DNA?

Back

Deoxyribose sugar is a five-carbon sugar molecule that is a component of DNA, forming part of the backbone of the DNA structure.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other, with a sugar-phosphate backbone and nitrogenous bases paired in the center.

Front

What is the significance of base pairing in DNA?

Back

Base pairing ensures accurate replication of DNA and the transmission of genetic information, as specific bases pair together (A with T and C with G).

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell duplicates its DNA before cell division, involving unwinding the double helix and synthesizing new complementary strands.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is usually single-stranded.
