Name the phenomenon which shows the lack of correlation in genome size and genetic complexity?
A.
Histogram
B.
Karyogram
C.
Dendrogram
D.
C-value paradox
Answer: Option D
Explanation:
In higher eukaryotes there is no connection between expanded genome size and multifaceted nature. This absence of the relationship between genome size and genetic complexity is called C-value paradox.
Genome size of eukaryotes varies accordingly, i.e. genome size of yeast is 12, mustard plant has size 120kb, fruit fly have 170kb, and humans have 3,300kb genome.
How does genome complexity of denatured DNA measure?
A.
Giemsa staining
B.
Reverse chromatography
C.
Denaturation kinetics
D.
Renaturation kinetics
Answer: Option D
Explanation:
Genome’s complex nature is the aggregate length of various arrangements of DNA. It can be estimated through the renaturation kinetics of denatured DNA.
Which of the following equation shows DNA renaturation reaction?
A.
Sec 60
B.
Cot1/2
C.
Tan 30
D.
Cot 40
Answer: Option B
Explanation:
Renaturation of DNA depends upon the random collision of the reciprocal strands and follow second order kinetics. A DNA renaturation (reassociation) response is given by the Cot1/2.
