Concept explainers
a)
Interpretation:
The mRNA strand from the given DNA template strand has to be predicted.
Concept Introduction:
RNA synthesis: The process of RNA synthesis is Transcription. A small section of DNA unwinds, only one of the two strands act as template and the other strand as informational strand. The complementary bases are attached one by one by the action of RNA polymerase at template strand on moving down. The newly generated RNA is the exact copy of the informational strand, with the exception that a U replaces each T in the template DNA. The RNA synthesised carries genetic information and directs protein synthesis.
Illustrated relationships are:
DNA informational strand: 5’ ATG CCA GTA GGC CAC TTG TCA 3’
DNA Template strand: 3’ TAC GGT CAT CCG GTG AAC AGT 5’
mRNA: 5’ AUG CCA GUA GGC CAC UUG UCA 3’
