Chemists at UCL (University College London) have shown how two of biology’s most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin ...

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins ...

Less than 10% of plastics are recycled. A Purdue-led team, backed by NSF, is creating durable bioplastics from raw materials ...

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and ...

Researchers have revealed early conditions under which RNA and amino acids may have combined, giving rise to the origin of ...
