Answer : b) The functional unit of DNA molecule that codes for a particular gene product c) Intervening non coding sequence of DNA...
RNA transcription is more complex in eukaryotes because it is first made as a primary RNA transcript that contains intron and exon sequences. What kind of modification must occur to produce a mature mRNA? Answer : RNA splicing. Introns must be removed and exons are spliced together to form a mature RNA transcript....
Select the incorrect statement out of the five given below about lac operon when Lactose is present in the medium. a) Gene - A gets transcribed into mRNA which produces β-galactoside permease b) ... polymerase transcribe Z-gene, Y-gene and A-gene e) Allolactose is the inducer of lac operon Answer : Gene – A gets transcribed into mRNA which produces β-galactoside permease b) Inducer-Repressor complex is formed...
