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
Nucleic acids exhibit secondary structure. Describe through Watson-Crick model.
$NHC$ structural proteins are
In an experiment, $DNA$ is treated with a compound which tends to place itself amongst the stacks of nitrogenous base pairs. As a result of this, the distancebetween two consecutive base increases. from $0.34- 0.44\,nm$ calculate the length of $DNA$ double helix $($ which has $2 \times 10^9\,bP)$ in the presence of saturating amount of this compound.
The diagram shows an important concept in the genetic implication of $DNA$. Fill in the blanks $A$ to $C$.
What background information did Watson and Crick have made available for developing a model of $DNA$ ? What was their contribution ?
