Question
There are seven chromosomes in the garden pea and seven independently assorting RFLPs are identified in this organism. These results fit the hypothesis that each RFLP maps to a different chromosome. True/False cDNA libraries possess promoter sequences True/False PCR is a method that allows you to amplify a specific DNA sequence True/False Heterochromatin sequences would most likely be present in genomic libraries True/False The probability of isolating a gene from a cDNA library is not dependent on the cell type from which the library was originally constructed True/FalseExplanation / Answer
1 True
According to Fit hypothesis one may be fit for that with special character and there other with same character may not be fit for that role by this we say that all these genes assort on different chromosomes.
2 False
cDNA contained information about the total clone DNA in host cells cDNA are most powerful gene product but lack information about enhancers, promoters, intron etc.
3 True
Polymerase chain reaction is technique used to amplify a single copy or few copies of segment of DNA across several magnitude generating thousands of copies of DNA sequence which is very cheap and reliable.
4 True
Genomic library contains heterochromatin, heterochromatin is a sequence of tightly packed DNA sequences and genomic libraries contain sequences of DNA of total organism.
5 True
Gene isolation of cDNA depends on the cell type from which the library was constructed because the expression of genes depends on naturally occurring enzymes reverse transcriptase.
