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 ...

The simplest way to decipher the code would be to start with an mRNA molecule of known sequence, use it to direct the synthesis of a protein, and then determine the amino acid sequence of the ...

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

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