Knowledge of the frequencies of synonymous triplets in protein-coding and non-coding DNA stretches can be used in gene finding. These frequencies depend on the GC content of the genome or parts of it.

How does DNA determine an organism’s characteristics? A process called translation decodes RNA created during transcription, and uses it to create proteins that perform specific cellular functions.

The genetic building blocks of life—formed from the four nucleotides adenine (A), cytosine (C), guanine (G), and thymine (T)—are read in groups of three known as codons. While some codons (known as ...

Somewhere in a sample of ordinary pond water, a single-celled organism has been quietly breaking one of biology’s most fundamental rules. Condylostoma magnum, a free-living ciliate barely visible to ...
