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.
EcosystemTropical Savanna is found between sections of tropical rain forest and deserts. They have 2 seasons; wet (constant humidity) and dry (long periods of dry spells and drought that may cause fires).
Both savanna buffalo and forest buffalo live close to water. The buffalo are found throughout the northern and southern savanna as well
as the lowland rain forest.
<span>How might this population suddenly increase? How might this affect the ecosystem? If there was an increase in population; grasslands during the wet season will be gone, more predators will flock for an abundance of buffalo.
</span>
<span>What might happen to the ecosystem if this population was removed? If you remove the buffalo from the savanna ecosystem, it can cause a ripple effect such as populations of small mammal (mouse) will double, which will attract more snakes (venomous), it can cause the flea and tick population to increase, and the increase in tick/fleas can cause the risk of transmission of flea/tick borne pathogens.</span>
The answer would be B for this question. ATP is used by the mitochondria the “power house” of the cell.
Answer: 25%?
Explanation: theres 4 children and the moms a carrier so 1/4 of 100 is 25%
