Front

Guanine bonds with ______________.

Back

Cytosine

Front

Which sequence of DNA bases would pair with this partial strand ATG TGA CAG?

Back

TAC ACT GTC

Front

Which 2 molecules form the sides (backbone) of the DNA ladder?

Back

deoxyribose (sugar) and phosphate

Front

What is a Double Helix?

Back

A pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule.

Front

Why is DNA important?

Back

It serves as the blueprint for traits of all living things.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

Name the four nitrogenous bases in DNA.

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is the role of DNA polymerase?

Back

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

Front

What is the function of the phosphate group in DNA?

Back

It forms the backbone of the DNA molecule, linking the sugar of one nucleotide to the sugar of the next.

Front

What is a gene?

Back

A unit of heredity which is transferred from a parent to offspring and determines some characteristic of the offspring.
