Packaging of $DNA$ helix
Involves polyamines in eukaryotes
Occurs with the help of $NHC$ proteins only
Requires acidic proteins that help in coiling of $DNA$ in prokaryotes
Is more complex in eukaryotes than prokaryotes
Assertion : Histones are basic proteins of major importance in packaging of eukaryotic $DNA$. $DNA$ and histones comprise chromatin forming the bulk of eukaryotic chromosome.
Reason : Histones are of five major types $H_1,\,H_2A\,, H_2B,H_3$ and $H_4$ .
What is the function of histones in $DNA$ packaging ?
In $DNA$ if $10\%$ guanine is present, how much thymine is present
The haploid content of human $DNA$ is
What is central dogma and describe the packing of $DNA$ helix ?
