How does the cell convert DNA into working proteins ... is known as the untranslated region (UTR) or leader sequence. This portion of mRNA is located between the first nucleotide that is ...

In a typical cell, genes encoded in DNA ... each mRNA that contains non-coding or untranslated RNA. Every mRNA has ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...

The sequence of base pairs in DNA determines the genetic code, which is read in triplets (codons) to specify the amino acid sequence of proteins. The complementary nature of base pairing allows for ...
