DNA Structure

Front

What are the three main components of a DNA nucleotide?

Back

1. Deoxyribose sugar 2. Phosphate group 3. Nitrogenous base

Front

What is the function of DNA polymerase during DNA replication?

Back

DNA polymerase builds the new DNA strand by adding nucleotides.

Front

What is a gene?

Back

A gene is a section of DNA that contains instructions for building proteins.

Front

What does DNA stand for?

Back

DNA stands for Deoxyribonucleic Acid.

Front

Where is DNA located in a cell?

Back

DNA is located in the nucleus of the cell.

Front

What is the role of the phosphate group in a DNA nucleotide?

Back

The phosphate group links the sugar of one nucleotide to the sugar of another, forming the backbone of the DNA strand.

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

How do the nitrogenous bases pair in DNA?

Back

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

Front

What is the shape of the DNA molecule?

Back

The DNA molecule has a double helix shape.

Front

What is the significance of the sequence of nitrogenous bases in DNA?

Back

The sequence of nitrogenous bases determines the genetic information and instructions for building proteins.
