DNA Structure and Replication

Front

What are the 4 nitrogen bases in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine.

Front

How is the instructions for your traits carried on a DNA molecule?

Back

Through the sequence of the nitrogen bases.

Front

What does DNA stand for?

Back

Deoxyribonucleic acid.

Front

What are nucleotides made of?

Back

A molecule of deoxyribose, a phosphate group, and a nitrogen base.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What is the role of DNA polymerase in replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of the phosphate group in DNA?

Back

The phosphate group links the sugar molecules of adjacent nucleotides, forming the backbone of the DNA strand.

Front

What is the significance of the sequence of nitrogen bases?

Back

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

Front

What is the process of DNA replication?

Back

The process by which DNA makes a copy of itself before cell division.

Front

What is the first step in DNA replication?

Back

Unwinding of the double helix by the enzyme helicase.
