Q2 An open reading frame (ORF) is a section of codons that begins with a start codon and ends with a stop codon. Each codon specifies for a specific amino acid. ORF is the part of a gene that after transcription into an mRNA gets translated into a protein. With the help of several translation factors and enzymes, ribosomes translate mRNAs into proteins. The following DNA sequence contains a complete open reading frame (ORF) of a short transcriptional unit. The...
