Mitosis – When a cell divides in two
Mitosis is the division of a single cell nucleus that results in two daughter nuclei with the same, duplicated genetic information.
Science
messenger RNA (mRNA) – The messengers of the genome
The messenger RNA or mRNA is single-stranded ribonucleic acid that is produced from DNA and encodes instructions for proteins.
Science
DNA Sequencing – Technologies to read the code of life
DNA sequencing describes methods of determining the order of nucleotides in a DNA molecule. It has revolutionized the study of genomics.

Genetic genealogy – Revealing ancestry and family relations using DNA
Genetic genealogy is the application of genetics to genealogy whereby DNA is analyzed to estimate the degree of kinship between individuals.
Science
What is a gene?
A gene is a functional unit of DNA that contains basic information for the development of characteristics of an individual.
