DNA Practice

Front

What type of structure does DNA have?

Back

Double Stranded Helix (Anti-parallel)

Front

What is the monomer (building block) of DNA and RNA?

Back

Nucleotide

Front

What are the three components of a nucleotide?

Back

A phosphate group, a sugar (deoxyribose in DNA, ribose in RNA), and a nitrogenous base.

Front

What are the four nitrogenous bases found in DNA?

Back

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

Front

How are traits determined in DNA?

Back

By the sequence of the nitrogenous bases.

Front

Where is DNA located in prokaryotic cells?

Back

In the cytoplasm (free floating).

Front

What is the function of DNA?

Back

To store and transmit genetic information.

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.

Front

What is the role of the sugar in a nucleotide?

Back

It forms the backbone of the DNA or RNA strand.

Front

What is complementary base pairing in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.
