Concept explainers
(a)
Interpretation:
The DNA template formed from mRNA sequence
Concept Introduction:
DNA is a molecule that is stranded with two polynucleotides into a double helix structure. The two polynucleotide strands are placed antiparallel to each other. It means that one strand starts from
In transcription, DNA strand separates and mRNA with DNA template is formed by the catalyzation of RNA polymerase. The mRNA molecule formed has base pairs opposite to DNA template.
RNA does not contain thymine base instead it has uracil base. Therefore, in this purine base adenine (A) is held with pyrimidine base uracil (U) by two hydrogen bonds. Whereas purine base guanine (G) is held with pyrimidine base cytosine (C) by three hydrogen bonds. These base pairs are denoted as
