Back

A pattern of DNA fragments obtained by examining a person's unique sequence of DNA pairs.

Front

What technique is used to analyze DNA by separating fragments based on size?

Back

Gel electrophoresis.

Front

What does it mean if a suspect's DNA matches the DNA found at a crime scene?

Back

It indicates that the suspect may have been present at the crime scene.

Front

What is a vector in biological terms?

Back

An organism that carries something, often used to transfer genetic material.

Front

How does DNA replication occur in terms of nucleotide orientation?

Back

DNA replication puts down nucleotides 5' to 3' and is said to be antiparallel.

Front

What are alleles?

Back

Different versions of a gene that can exist at a specific locus on a chromosome.

Front

What is the role of chromosomes in genetics?

Back

Chromosomes are structures that organize and carry genetic information in the form of DNA.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

They indicate the directionality of the DNA strand, which is crucial for replication and transcription.

Front

What is the purpose of DNA sequencing?

Back

To determine the exact order of nucleotides in a DNA molecule.

Front

What is genetic engineering?

Back

The manipulation of an organism's DNA to achieve desired traits.
