A DNA sequence that forms the blueprint for the synthesis of a polypeptide.
Industry:Biotechnology
A DNA sequence that helps to reduce or shut off the expression of a nearby gene.
Industry:Biotechnology
A DNA sequence used to "mark" or track a particular location (locus) on a particular chromosome.
Industry:Biotechnology
A DNA strand that is synthesized during the polymerase chain reaction and has a primer sequence at one end and a sequence complementary to the second primer at the other end.
Industry:Biotechnology
A DNA strand that is synthesized during the polymerase chain reaction and has a primer sequence at one end but is extended beyond the site that is complementary to the second primer at the other end.
Industry:Biotechnology
A double heterozygote that contains two mutations arranged in the <i>trans</i> configuration.
Industry:Biotechnology
A double-ring, nitrogen-containing base present in nucleic acids; adenine (A) and guanine (G) are the two purines present in most DNA and RNA molecules.
Industry:Biotechnology
A double-stranded DNA molecule or DNA-RNA hybrid, where each strand is of a different origin, and consequently containing one or more mismatched (non-complementary) base pairs. A DNA duplex is prepared by the hybridization of single-stranded DNA molecules derived from two different sources. Where the two DNAs have identical or very similar sequences, a double-stranded molecule will be established, whereas where the two DNAs differ in sequence, single-stranded regions will remain. A heteroduplex will be revealed as single-strand "bushes" when DNA is observed electron microscopically. A map of homologous and non-homologous regions of the two molecules may thereby be constructed. This process is known as heteroduplex mapping.
Industry:Biotechnology
A double-stranded DNA molecule that is carried in a vector and was synthesized <i>in vitro</i> from an mRNA sequence by using reverse transcriptase and DNA polymerase.
