DNA Replication L.16.3

Front

What is the role of DNA in living organisms?

Back

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

Front

What does the semi-conservative model of DNA replication imply?

Back

In the semi-conservative model, the daughter DNA molecule consists of 1 parent strand and 1 new strand.

Front

When does DNA replication occur in the cell cycle?

Back

DNA replication occurs before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions.

Front

Why can bacteria produce human proteins?

Back

Bacteria can recognize a human gene and produce a human protein because the basic components of DNA are the same in humans and bacteria.

Front

What is the complementary DNA strand for AATCATGGA?

Back

The complementary strand is TTAGTACCT.

Front

Define DNA replication.

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What are the basic components of DNA?

Back

The basic components of DNA are nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What base pairs with adenine in DNA?

Back

Thymine (T) pairs with adenine (A) in DNA.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.
