DNA Fingerprinting
-
PCR and Restriction Fragment Length Polymorphism are the methods forDNA (genetic) fingerprinting identifies differences in repetitive DNA between individuals.
RFLP detects differences in the lengths of restriction fragments, and PCR amplifies very small DNA samples for this analysis.
Transcription
-
Which one of the following is not a part of a transcription unit in DNA?A transcription unit in DNA is defined by three regions: a promoter, the structural gene and a terminator.
An inducer (such as lactose in the lac operon) is a regulatory molecule, not a part of the DNA transcription unit. -
If one strand of DNA has the nitrogenous base sequence as ATCTG, what would be the complementary RNA strand sequence?In RNA, A of DNA pairs with U, T pairs with A, C pairs with G and G pairs with C.
DNA: A T C T G
RNA: U A G A C
So the complementary RNA strand is UAGAC.
RNA processing
-
Removal of introns and joining of exons in a defined order during transcription is calledIn eukaryotes the primary transcript (hnRNA) contains both exons (coding) and introns (non-coding).
The introns are removed and the exons are joined in a defined order. This process is called splicing.
Along with capping and tailing, splicing converts hnRNA into functional mRNA.
That is every question in Molecular Basis of Inheritance for this filter.
