DNA Structure

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands that wind around each other, consisting of nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the base pairing rule in DNA?

Back

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

Front

What type of bond holds the nitrogenous bases together?

Back

Hydrogen bonds hold the nitrogenous bases together.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of DNA in living organisms?

Back

DNA carries genetic information that determines the traits and functions of living organisms.

Front

How does DNA replicate?

Back

DNA replication involves unwinding the double helix and using each strand as a template to create a new complementary strand.

Front

What is the significance of the sequence of nucleotide bases?

Back

The sequence of nucleotide bases determines the genetic code and specific traits of an organism.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.
