Structure of DNA

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, resembling a twisted ladder.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the four nitrogen bases found in DNA?

Back

The four nitrogen bases in DNA are adenine, thymine, cytosine, and guanine.

Front

Why is DNA considered the blueprint of life?

Back

DNA serves as the blueprint for traits of all living things.

Front

What forms the backbone of the DNA molecule?

Back

The backbone of DNA is formed by deoxyribose (sugar) and phosphate.

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine pairs with thymine, and cytosine pairs with guanine.

Front

What is the role of hydrogen bonds in DNA?

Back

Hydrogen bonds hold the two strands of DNA together by connecting the nitrogen bases.

Front

How does DNA replicate?

Back

DNA replicates by unwinding and separating the two strands, allowing new nucleotides to pair with the exposed bases.

Front

What is the significance of complementary base pairing?

Back

Complementary base pairing ensures accurate DNA replication and the preservation of genetic information.

Front

What is the difference between DNA and RNA?

Back

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