The following statements are true about the modification of chromatin structures in the eukaryotes:
1. Melthylation of histone tails in chromatin can promote condensation of the chromatin.
2. DNA is not transcribed when chromatin is package tightly in a condensed form.
3. Acetylation of histone tails in chromatin allows access to DNA for transcription.
4. Some form of chromatin modifications can be passed on to future generation of cells.
5. Acetylation of histone tails is a reversible process.
Answer: Lac operon
Explanation: the same cells when grown in glucose media utilize the glucose as source if energy by blocking the activity of the enzyme beta- galactosidase. the operator site of the operon is blocked thereby preventing the activity of the collective functional genes.
Yes calcium ion channels open and cause the neurotransmitters to move as well
<span>In looking at a section through the brain, you see a neuron with a number of shrub like projections extending from one side of the cell body and a single long projection extending from the other side. the shrub like projections are most likely dendrites, and the single long projection is most likely axons.</span>
