Chapter Test: DNA

Front

What is the monomer of DNA?

Back

Nucleotide

Front

Define transformation in the context of genetics.

Back

A permanent change in the genetic composition of an organism.

Front

What is the starting point of DNA replication in prokaryotes?

Back

Replication starts from a single point and proceeds in two directions until the entire chromosome is copied.

Front

What do Chargaff's rules of base pairing explain?

Back

DNA is double stranded, and hydrogen bonds between base pairs hold the two strands together.

Front

What was concluded from the Hershey-Chase experiment regarding bacteriophages?

Back

Bacteriophages inject their DNA into the bacterial cells.

Front

What are nucleotides composed of?

Back

A phosphate group, a sugar, and a nitrogenous base.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the double helix structure of DNA?

Back

It allows for the stable storage of genetic information and the accurate replication of DNA.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

How do base pairs in DNA pair with each other?

Back

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