DNA that has been synthesized from mRNA by the action of reverse transcriptase.

. Single-stranded DNA synthesized in the laboratory using messenger RNA as a template and the enzyme reverse transcriptase. Complementary strand in American English. Either of the two chains that make up a double helix of DNA with corresponding positions on the two chains being composed of a pair of complementary bases.

What is the complementary strand. It is complementary to the coding strand of DNA for the target gene. Complementary DNA cDNA is synthesized in the laboratory from messenger RNA Fig.

The RNA sequence which is made up of a direct copy of the nitrogenous bases in the template strand. Either of the two chains that make up a double helix of DNA with corresponding positions on the two chains being composed of a pair of complementary bases. This is what we call complementary base pairing.

Complementary DNA cDNA 1. Definition of complementary strand 1. A section of one nucleic acid chain that is bonded to another by a sequence of base pairs.

Farlex Partner Medical Dictionary Farlex 2012. In genetics complementary DNA is DNA synthesized from a single-stranded RNA template in a reaction catalyzed by the enzyme reverse transcriptase. What is meant by complementary DNA.

Complementary DNA is used for many purposes such as mapping chromosomes creating clones and sequencing genes. In biology specifically in terms of genetics and DNA complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement or the pair of the other strand. So the two strands of DNA are said to complement each other.

The American Heritage Science Dictionary Copyright 2011. Complementary DNA cDNA is a DNA copy of a messenger RNA mRNA molecule produced by reverse transcriptase a DNA polymerase that can use either DNA or RNA as a template. Complementary deoxyribonucleic acid DNA is DNA in which the sequence of the constituent molecules on one strand of the double stranded structure chemically matches the sequence on the other strand.

In genetics complementary DNA cDNA is DNA synthesized from a single-stranded RNA eg messenger RNA mRNA or microRNA miRNA template in a reaction catalyzed by the enzyme reverse transcriptase. CDNA complementary DNA - single-stranded DNA that is complementary to messenger RNA or DNA that has been synthesized from messenger RNA by reverse transcriptase episome - DNA that is not incorporated into the genome but is replicated together with the genome especially in bacterial cells. The genetic material of a virus as incorporated into and able to replicate with the genome of a host cell.

CDNA is often used to. CDNA is often used to clone eukaryotic genes in prokaryotes. Replicative form RF 2.

A section of one nucleic acid chain that is bonded to another by a sequence of base pairs. A section of one nucleic acid chain that is bonded to another by a sequence of base pairs. The altered double-stranded form to which single-stranded coliphage DNA is converted after infection of a susceptible bacterium formation of the complementary minus strand being mediated by enzymes that were present in the bacterium before entrance of the viral plus strand.

Complementary strand definition either of the two chains that make up a double helix of DNA with corresponding positions on the two chains being composed of a pair of complementary bases. CDNA is not genomic DNA because the transcript of genomic RNA has been processed ie it lacks promoters and introns. The complementary strand of the DNA is the one which is not used and is called as the nonsense strand or the antisense strand.

Complementary DNA - single-stranded DNA that is complementary to messenger RNA or DNA that has been synthesized from messenger RNA by reverse transcriptase cDNA provirus - cDNA copy of the RNA genome of a retrovirus. The enzyme reverse transcriptase see Chapter 15 is used to synthesize double-stranded DNA that is a complementary copy of the mRNA. The two strands are described as complementary to one another.

When scientists want to express a specific protein in a cell that does not normally express that protein they will transfer the cDNA that codes for the protein to the. Complementary deoxyribonucleic acid DNA is DNA in which the sequence of the constituent molecules on one strand of the double stranded structure chemically matches the sequence on the other strand. The complementary DNA strand the one that is not used is called the nonsense or antisense strand.

The template strand of DNA is the strand that is used during transcription to produce RNA. Complementary strand in American English. Either of the two chains that make up a double helix of DNA with corresponding positions on the two chains being composed of a pair of complementary bases.

Definition of complementary strand 1. Complementary strand - WordReference English dictionary questions discussion and forums. Single-stranded DNA that is complementary to messenger RNA.

The bottom strand of the substrate is the complementary sequence of the top strand Specific genes are then identified and quantified by hybridization to a labelled DNA probe of a complementary sequence We report unbinding force measurements between complementary strands of DNA as a function of temperature.
