A

Autosomes

Any chromosome in the body other than the sex chromosomes.

B

Base Pairs

The sets of hydrogen-linked nucleobases (adenine and thymine or guanine and cytosine), that keep the two strands of DNA together.

B

Bioinformatics

The collection, classification, storage, and analysis of biochemical and biological information using computer programs.

C

Chromosomes

Thread-like structures found in the nucleus that contain DNA.

D

DNA

A double helical nucleic acid molecule forming the molecular basis of heredity.

D

DNA Profiling

The process of determining a person’s DNA characteristics which are as unique as fingerprints, hence also called as DNA fingerprinting. The specific DNA pattern developed is called a DNA profile.

G

Gene

A gene is a sequence of nucleotides in DNA or RNA that codes for a molecule that has a function.

G

Genome

All the DNA in a cell. The genome comes in the form of 23 pairs of chromosomes.

G

Genotyping

A technology that looks at single bases (adenine, cytosine, thymine, and guanine) in the genome.

I

Inheritance

Inheritance is the process by which genetic information is passed from parent to child. This is why members of the same family tend to have similar characteristics.

L

Locus / Loci

A locus is a position on a chromosome, a region of DNA that’s analysed. “Loci” is the plural of “locus.”

P

Phenotype

Physical characteristics or appearance of a trait.

V

Variation

A single difference in the DNA between two people. These differences are normal and an important part of what makes every person unique.
