DNA structure

Front

What holds the backbone of DNA together?

Back

Covalent bonds hold the backbone of DNA together, ensuring the sequence doesn't get out of order.

Front

What is one primary function of DNA?

Back

One primary function of DNA is to code for proteins.

Front

What is the backbone of DNA made of?

Back

The backbone of DNA is made of sugars and phosphates.

Front

Is bacterial DNA structurally the same as human DNA?

Back

True, structurally speaking, bacterial DNA looks the same as human DNA.

Front

What does semiconservative replication mean in DNA replication?

Back

Semiconservative replication means that one strand of DNA is kept as a template to build the other new strand.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a 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 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 shape of the DNA molecule?

Back

The shape of the DNA molecule is a double helix.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain.
