If a DNA strand has the sequence: AAT GCA, what is the complementary strand?

Back

TTA CGT

Front

Replication

Back

To copy

Front

Why does your DNA have to replicate?

Back

During mitosis, your cells divide into 2 new cells

Front

In which phase of the cell cycle does DNA replicate?

G1

,

S

,

G2

,

Mitosis

Back

S

Front

Function of helicase?

Back

It unwinds the DNA strand

Front

What is the function of DNA polymerase?

Back

It builds & edits the new DNA strand

Front

Function of ligase?

Back

It re-seals the DNA strand

Front

DNA is double-stranded. In replication, each new DNA molecule is made of:

2 entirely new DNA strands

,

2 old parent strands

,

1 old strand + 1 new strand

Back

1 old strand + 1 new strand

Front

Which best describes a mutation?

Back

A mistake / error in a DNA strand

Front

At the end of replication, the 2 new DNA molecules are:

Back

Identical
