Answer:
Acetylation of histone tails is a reversible process.
DNA is not transcribed when chromatin is packaged tightly in a condensed form.
Methylation of histone tails in chromatin can promote condensation of chromatin.
Acetylation of histone tails in chromatin allows access to DNA for transcription.
Eukaryotic chromatin structure is a highly complex assembly which needs to be simplified in order to undergo process of transcription. Eukaryotic chromatin structure is highly condensed in nature and DNA cannot be access for transcription. Actylation of histone tails is a process in which breaks the bond of attraction between adjacent nucleosomes. It results in chromatin being condensed attains a loose form. Transcription of DNA can occur in a loose chromatin. Methylation can promote condensation or decondensation of chromatin structure depending upon the methyl group present in the histone.
Since diabetics are not able to make enough insulin, scientists use gene engineering to make it for them. they insert the gene that codes for the production of insulin in the plasmid (circular DNA of bacteria ) to create recombinent DNA, and the bacteria will asexually reproduce, making more and more of the insulin in a short amount of time! hope this helped it took me a long time to understand the whole process in this unit!
Answer:
Water is transported from one area to another area that has little water.
Water is collected and salt allowed to settle at the bottom.
Explanation:
Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.
Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.
Ocean plants absorb co2 just like trees do. Any co2 that’s not fixed will mess up the chemistry of the waters
