When this happens during DNA replication, the result is an unpredictable change in the nucleotide sequence of an organism's DNA. This process, called mutation, is part of what determines changes ...

This portion of mRNA is located between the first nucleotide that is transcribed and the start codon (AUG) of the coding region, and it does not affect the sequence of amino acids in a protein ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing ...

For example, a sequence for an mRNA molecule might be: AUG-GGU-CAA-UAA. Each one of these codons corresponds to a specific ...

Researchers developed a technique to gain a deeper understanding of ribosome function and their cooperative behaviors.

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

The tRNA binds to its corresponding amino acid and transports it to the ribosome ... These small RNAs can bind to complementary mRNA sequences, triggering their degradation or preventing their ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed ... Peptide bonds form between the adjacent amino acids to finalise the structure.
