<u>Answer:</u>
The type of change that was responsible was “histone acetylation or DNA methylation”.
<u>Explanation:</u>
- Histone acetylation is the process that involves the epigenetic adjustments that functions in the transcription process while regulating DNA.
- Histone acetylation or DNA methylation is the major component of the gene regulation while passing from one generation to another.
- The Acetyl groups are hooked up to lysine’s in histone tails so their charges play a vital role to avoid the histone tail to bind with the other molecules.
Glassy igneous rocks (i.e. obsidian) are cooled very rapidly.
In the presence of lactose, the gene for beta-galactosidase is turned on by induction. The RNA polymerase binds to the promoter, in the presence of lactose. Lactose binds to repressor leading to structural changes so that it does not bind to the promoter. This leads to the production of beta-galactosidase which breaks the bond between glucose and galactose, for utilization of lactose.
