What is the shape of the DNA molecule?

• Single strand

• Double helix

• Square

• Triangle

What is the function of DNA?

• DNA regulates cell division

• DNA is responsible for protein synthesis

• DNA stores and transmits genetic information.

• DNA is used for energy production

How many base pairs are there in the human genome?

• 3.2 billion

• 2.5 billion

• 1.8 billion

• 4.7 billion

What is the process of copying DNA called?

• DNA replication

• DNA duplication

• DNA mirroring

• DNA synthesis

What is a mutation in DNA?

• A mutation in DNA is a permanent alteration in the DNA sequence that makes up a gene.

• A mutation in DNA is a physical rearrangement of the DNA structure

• A mutation in DNA is a temporary alteration in the DNA sequence

• A mutation in DNA is a reversible change in the DNA sequence

What is the role of DNA in protein synthesis?

• DNA provides the genetic code for protein synthesis.

• DNA is responsible for transporting proteins to the ribosomes.

• DNA determines the final shape of the protein.

• DNA acts as a catalyst in the protein synthesis process.

How does DNA differ from RNA?

• DNA is single-stranded with ribose sugar and thymine, while RNA is double-stranded with deoxyribose sugar and uracil.

• DNA and RNA are both double-stranded but differ in the type of bonds that hold the strands together.

• DNA is double-stranded with deoxyribose sugar and thymine, while RNA is single-stranded with ribose sugar and uracil.

• DNA and RNA have the same sugar backbone but differ in the nitrogenous bases they contain.
