A microscopic organism from a freshwater pond is playing by a different set of genetic rules. The newly identified protist, ...

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 ...

The genetic code is made up of a total of 64 base triplets or codons. At least one codon encodes the information for each of the 20 amino acids used in the synthesis of proteins during translation.

Superimposed on the genetic sequences coding for amino acids is a second genetic code. This second genetic code, which makes use of dual-use codons, or duons, specifies how genes are controlled. The ...

For decades, scientists working with genetic material have labored with a few basic rules in mind. To start, DNA is transcribed into messenger RNA (mRNA), and mRNA is translated into proteins, which ...

Our genes are written in long strings of three-letter units composed of four different nucleotides. These units - or codons - specify one of many amino acids, the building blocks of proteins. Multiple ...

Scientists accidentally discovered a microscopic organism with a genetic code that breaks a rule researchers thought was ...

A central tenet of biology may need updating given new measurements of start codons. For decades, scientists working with genetic material have labored with a few basic rules in mind. To start, DNA is ...
