What would happen if histones were to be mutated and made rich in acidic amino acids such as aspartic acid and glutamic acid in place of basic amino acids such as lysine and arginine?
If histone proteins were rich in acidic amino acids instead of basic amino acids then they may not have any role in $DNA$ packaging in eukaryotes as $DNA$ is also negatively charged molecule. The packaging of $DNA$ around the nucleosome would not happen. Consequently, the chromatin fibre would not be formed.
The double helix model of Watson and Crick is known as
Definitions/Explanation : Histone octomer & Euchromatin
Identify the basic amino acid from the following.
The term 'Nuclein' for the genetic material was used by
If the length of E. Coli $DNA$ is $1.36 \;mm$, calculate the number of base pairs in E. Coli.
