DNA structure

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides twisted around each other.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a deoxyribose sugar, a phosphate group, 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 the nitrogenous bases pair in DNA?

Back

Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What does the 'D' in DNA stand for?

Back

The 'D' in DNA stands for deoxyribo, referring to the deoxyribose sugar in its structure.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What role do enzymes play in DNA replication?

Back

Enzymes such as DNA polymerase help to unwind the DNA strands and synthesize new complementary strands.

Front

What is a gene?

Back

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

Front

Can human genes be inserted into bacteria?

Back

Yes, human genes can be inserted into bacteria, allowing them to produce human proteins.
