What is the basic structure of DNA?

• triple helix

• single strand

• double helix

• quadruple helix

What are the three components of a nucleotide?

• sugar molecule, phosphate group, nitrogenous base

• sugar molecule, phosphate group, amino acid

• sugar molecule, phosphate group, fatty acid

• sugar molecule, phosphate group, nucleic acid

Which nitrogenous bases are found in DNA?

• adenine, thymine, cytosine, guanine

• adenine, uracil, cytosine, guanine

• adenine, thymine, cytosine, uracil

• adenine, thymine, uracil, guanine

What is the function of DNA in cells?

• Produce energy for the cell.

• Regulate cell division.

• Facilitate protein synthesis.

• Store and transmit genetic information

How is DNA organized in the cell?

• mitochondria

• proteins

• nucleotides

• chromosomes

What is the complementary base pairing rule in DNA?

• Adenine (A) pairs with Cytosine (C), and Guanine (G) pairs with Thymine (T).

• Adenine (A) pairs with Uracil (U), and Guanine (G) pairs with Cytosine (C).

• Adenine (A) pairs with Guanine (G), and Thymine (T) pairs with Cytosine (C).

• Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C)

What is the difference between a purine and a pyrimidine?

• Purines are larger molecules than pyrimidines.

• The main difference between a purine and a pyrimidine is their structure. Purines have a double-ring structure, while pyrimidines have a single-ring structure.

• Purines are found in DNA, while pyrimidines are found in RNA.

• Purines are involved in energy transfer, while pyrimidines are involved in protein synthesis.

What is the role of nucleotides in protein synthesis?

• Nucleotides carry the genetic information from DNA to the ribosomes during protein synthesis.

• Nucleotides regulate the speed of protein synthesis.

• Nucleotides act as building blocks for proteins during synthesis.

• Nucleotides provide energy for protein synthesis.

What is the structure of a nucleotide?

• A nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base.

• A nucleotide consists of a sugar molecule and a phosphate group.

• A nucleotide consists of a phosphate group and a nitrogenous base.

• A nucleotide consists of a sugar molecule and a nitrogenous base.

How does DNA replication occur?

• DNA replication occurs through a conservative process.

• DNA replication occurs through a dispersive process.

• DNA replication occurs through a random process.

• DNA replication occurs through a semi-conservative process.
