DNA Practice

Front

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

Back

Nucleotide

Front

What accounts for the difference in hair texture between siblings?

Back

The sequence of nitrogen bases is different between individuals.

Front

How are traits determined in DNA?

Back

Traits are determined by the sequence of nitrogenous bases.

Front

What type of structure does DNA have?

Back

Double Stranded Helix (Anti-parallel)

Front

What is the role of nitrogenous bases in DNA?

Back

Nitrogenous bases encode genetic information and determine traits.

Front

What are the four nitrogenous bases found in DNA?

Back

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

Front

What is the complementary base pairing in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is the significance of the anti-parallel structure of DNA?

Back

It allows for proper base pairing and replication of DNA.

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 a gene?

Back

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