When the scientist want to make a DNA fingerprint but she has a very small DNA the next step she needs to perform is polymerase chain reaction (PCR).
The polymerase chain reaction is a technique which is used to make several copies of any desired DNA segment.
A single polymerase chain reaction cycle consists of many steps and this PCR cycle can be repeated many times to amplify the DNA sample and get several numbers of copies which can be up to millions.

What happens to DNA during the S stage of interphase

Debora [2.8K]

Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids
