Complementary DNA (cDNA) is DNA that has been copied from an mRNA through a reverse transcriptase enzyme.

cDNA contains a copy of the original DNA sequence that made the mRNA - but without the introns (as these are cut out to create mRNA).

What is meant by the term complementary base pairing in genetics?

Complementary base pairing in genetics refers to the specific pairing of nucleotide bases in DNA molecules. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is essential for DNA replication and the transmission of genetic information.

How are complementary of DNA held together?

Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.


What does complementary bases in the structure of DNA mean?

The structure of DNA relies on a base-pairing rule. This means that in DNA, Adenine binds to Thymine and Guanine binds to Cytosine. The complementary base is the base that binds to the base in question. Therefore A is complementary to T, C is complementary to G, etc. So if you had a strand of DNA, for example; ATT-CCA-GTC The complementary strand (which would bind to the above) would be; TAA-GGT-CAG


What is the dna segment of ugauuc from mRNA?

The DNA segment complementary to the mRNA sequence "UGAUUC" would be "ACTAAG". This is because in DNA, adenine pairs with thymine and cytosine pairs with guanine. Thus, the complementary DNA sequence of the mRNA sequence is determined by replacing each base with its complementary base.


Guanine is a complementary base for which of these DNA nucleotides?

Guanine is a complementary base for cytosine in DNA.

What is the complementary DNA chain of 5'-AATGSTA-3'?

Do you mean complementary DNA chain of 5'-AATGCTA-3' (not 5'-AATGSTA-3')A(adenine) bonds with T(thymine) and G(guanine) bonds with C (cytosine). So the complementary DNA strand would be: 3'-TTACGAT-5' .


Which enzyme is responsible for adding complementary DNA bases to an exposed DNA strand?

The enzyme responsible for adding complementary DNA bases to an exposed DNA strand is DNA polymerase.
