Bio8: Flashcards: DNA & DNA Replication

Front

What is DNA?

Back

A molecule that carries genetic instructions for all living organisms.

Front

What is a Nucleotide?

Back

The building block of DNA, made of a sugar, phosphate group, and a nitrogen base.

Front

What is the Base Pairing Rule in DNA?

Back

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

Front

What is the shape of DNA?

Back

The twisted ladder shape known as the Double Helix.

Front

What is the function of Helicase?

Back

The enzyme that unwinds and unzips the DNA strands.

Front

What does DNA Polymerase do?

Back

The enzyme that adds complementary nucleotides during replication.

Front

What is a Replication Fork?

Back

The Y-shaped region where DNA is split for copying.

Front

What is Semi-Conservative Replication?

Back

Each new DNA molecule contains one original strand and one new strand.

Front

What is RNA?

Back

A single-stranded molecule that helps in making proteins.

Front

What is mRNA?

Back

Messenger RNA that carries the genetic code from DNA to the ribosome.
