Structure of DNA

Front

In DNA, which base pairs with Adenine?

Back

Thymine

Front

What is the structure of a nucleotide?

Back

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

Front

What are the two molecules that form the sides (backbone) of the DNA ladder?

Back

Deoxyribose (sugar) and phosphate.

Front

What is the primary function of DNA?

Back

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

Front

What is the role of the phosphate group in DNA?

Back

The phosphate group forms part of the backbone of the DNA structure, linking the deoxyribose sugars.

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine.

Front

What type of bond forms between the nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What is the shape of the DNA molecule?

Back

The DNA molecule has a double helix shape.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.

Front

How does DNA replicate?

Back

DNA replicates through a process called semi-conservative replication, where each strand serves as a template for a new strand.
