After translation, the single-stranded mRNA portions of the fusions will be converted to heteroduplex of RNA/DNA by reverse transcriptase to eliminate any unwanted RNA secondary structures, and render the nucleic acid portion of the fusion more stable. This step is a standard reverse transcription reaction.

A ribosome is made up of two subunits, a small subunit, and a large subunit. These subunits come together before the translation of mRNA into a protein to provide a location for translation to be carried out and a polypeptide to be produced. [3] The choice of amino acid type to add is determined by a messenger RNA (mRNA) molecule. Each amino ...
Given a protein sequence, a family of possible coding DNA sequences can be derived by reverse translation of the genetic code. Once candidate DNA sequences have been determined, it is a relatively straightforward algorithmic problem to efficiently search a target genome for matches, complete or partial, and exact or inexact.
Since DNA is interpreted in groups of three nucleotides (codons), a DNA strand has three distinct reading frames. [15] The double helix of a DNA molecule has two anti-parallel strands; with the two strands having three reading frames each, there are six possible frame translations. [15] Example of a six-frame translation.
Reverse genetics is a method in molecular genetics that is used to help understand the function(s) of a gene by analysing the phenotypic effects caused by genetically engineering specific nucleic acid sequences within the gene.

This is a graphical representation of the HIV1 frameshift signal. A −1 frameshift in the slippery sequence region results in translation of the pol instead of the gag protein-coding region, or open reading frame (ORF). Both gag and pol proteins are required for reverse transcriptase, which is essential to HIV1 replication. [7]
