What is the primary function of DNA in cells?

• To create cellular energy

• To serve as the cell's structural framework

• To store and transmit genetic information

• To assist in cell movement

Answer explanation

The primary function of DNA in cells is to store and transmit genetic information.

Where in the cell are chromosomes located?

• Cytoplasm

• Mitochondria

• Nucleus

• Cell membrane

Answer explanation

Chromosomes are located in the nucleus of the cell, not in the cytoplasm, mitochondria, or cell membrane.

What is a gene?

• A segment of DNA that codes for a protein

• A type of chromosome

• A cell without a nucleus

• A protein that helps in cell division

Answer explanation

A gene is a segment of DNA that codes for a protein, making the correct choice the one that defines it accurately.

How are inherited traits passed from parents to offspring?

• Through proteins

• Through cell membranes

• Through genes

• Through mitochondria

Answer explanation

Inherited traits are passed from parents to offspring through genes, which carry the genetic information that determines specific traits in an individual.

What is the shape of the DNA molecule?

• Single pentagon

• Double helix

• Triple octagon

• Quadruple triangle

Answer explanation

The shape of the DNA molecule is a double helix, consisting of two strands that wind around each other in a spiral formation.

What is the role of the nucleus in a cell?

• It digests food particles.

• It stores the cell's hereditary material.

• It produces energy for the cell.

• It acts as the cell's boundary.

Answer explanation

The nucleus stores the cell's hereditary material, such as DNA, and is responsible for controlling the cell's activities.

Which of the following best describes a chromosome?

• A type of cell

• A molecule of protein

• A structure that contains DNA

• A segment of RNA

Answer explanation

A chromosome is a structure that contains DNA, making it the best description among the options provided.

Which of the following is a characteristic of inherited traits?

• They can be acquired during the organism's lifetime.

• They are passed from parent to offspring through genes.

• They do not influence the organism's survival.

• They are always visible.

Answer explanation

Inherited traits are passed from parent to offspring through genes, highlighting the correct choice.

Why is the nucleus often referred to as the "control center" of the cell?

• It controls the movement of the cell.

• It contains the genetic material that regulates cell functions.

• It is responsible for the digestion of nutrients.

• It produces energy for the cell.

Answer explanation

The nucleus is referred to as the 'control center' of the cell because it contains the genetic material that regulates cell functions.
