DNA Structure and Function

Front

What is DNA?

Back

DNA stands for deoxyribonucleic acid, which is the molecule that carries the genetic instructions for life.

Front

What are the basic building blocks of DNA?

Back

The basic building blocks of DNA are nucleotides.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other.

Front

What are the components of a nucleotide?

Back

A nucleotide is made up of a phosphate group, a 5-carbon sugar (deoxyribose), and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do nitrogenous bases pair in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the function of DNA?

Back

The primary function of DNA is to store and transmit genetic information that guides the development and functioning of living organisms.

Front

What is the role of DNA in protein synthesis?

Back

DNA codes for proteins by providing the instructions for the sequence of amino acids in a protein.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is replication in the context of DNA?

Back

Replication is the process by which DNA makes a copy of itself before cell division.
