please explain the messelson and stahl's experiment
WHAT U MEAN BY DNA FINGERPRINTING?EXPLAIN
PLZ XPLAIN BARR BODY..?
Why the distance between two polynucleotide chains remain constant...??
a vector is engineered with three features which facilitate its cloning within the host cell. list the three features and explain each one of them.
What is Euchromatin and Heterochromatin ?
what is the difference between cistron and operon.
The two polynucleotide chains are coiled in a right handed fashion. What does this statement actually means ?

what does it mean that the phosphate moiety remains free at 5'
why there is 3 hydrogen bonds between guanine and cytocine and 2hydrogen bonds between adenine and thymine
briefly explain me the process of DNA replication, transcription and translation.
why galactose or glucose cannot act as inducer in lac operon???
1)why does DNA replication occur in small replication forks not in its entire length? 2)why is DNA replication continuous and discontinuous in a replication fork? 3)explain the importance of "origin of replication" in a replication fork.
how is lac operon switches on and off .how does it sfunctions are activated and inhibited
what is meant by capping and tailing in transcription process in eukaryotes?
what is the similarities between DNA polymerase and RNA polymerase
what is satellite dna in a genome?explain their role in dna finger printing?
In prokaryotes well defined nucleus is absent and DNA is scattered bt in our ncert text book it is given that DNA is not scattered throughout the cell,...its tooo confusing...what to refer plzz help me out..!!!

when and what end does the tailing of hnRNA take place?
if ecoli was allowed to grow for 80 minutes then what would be the propotion of light and hybrid density of Dna molecule?
What is the function of amino-acyl-tRNA synthetase?
pls explain replication of dna and semiconservative nature of dna i detail?
A geneticist isolates a gene for a specific traits under study, she also isolate the corresponding mRNA. Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA?
(a) Yes, mRNA is made from a DNA template and should be the same length as the gene sequence. (b) Yes, the mRNA should contain more bases than the DNA sequence because bases flanking the gene are also transcribed. (c) No, the final mRNA contains only exons, the introns were removed. (d) No, the mRNA was partially degraded after it was transcribed.
what you mean by saying haploid content of human dna is 3.3*109 base pairs?
