Characteristics are passed from parents to offspring. A gene is a small section of DNA that codes for a characteristic (e.g. eye colour). Alleles are different forms of the same gene, for example ...

Each gene might have different forms, and these are called alleles. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and genes.

In the pursuit of understanding the pathogenic expression mechanisms of bacteria and the advancements in biofoundry ...

Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or DNA. Encoded within this DNA are the directions ...

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA.
