NC Biology Essential Standard 3.1

Front

What part of a nucleotide accounts for the genetic variation between individuals?

Back

Nitrogenous base

Front

What are the 4 nitrogen bases in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine

Front

What is another name for a point mutation?

Back

Substitution

Front

What shows the correct complementary base pairing for DNA?

Back

Adenine pairs with Thymine (A-T) and Guanine pairs with Cytosine (G-C)

Front

Which nitrogen base does Adenine bond with?

Back

Thymine

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein function.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation involves a change in a single nucleotide, while a frameshift mutation involves the insertion or deletion of nucleotides, altering the reading frame.

Front

What are purines and pyrimidines?

Back

Purines are nitrogenous bases with a double-ring structure (Adenine and Guanine), while pyrimidines have a single-ring structure (Cytosine, Thymine).
