Answer:
Yes, the moon is accelerating.
Explanation:
The moon is known to orbit around the sun at an average speed of 2,288 miles an hour. This translates to about 3,386 kilometers an hour. Further, it means that through its whole period of acceleration, it travels a distance of about 1,423,000 miles or 2,290,000 kilometers.
Answer:
Some forms of chromatin modification can be passed on to future generation of cells
Acetylation of histone tails in chromatin allows access to DNA for transcription
DNA is not transcribed when packaged tightly in a condensed form
methylation of histone tails can promote condensation of the chromatin
Explanation:
chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.
<span>Deoxyribose is the same as ribose, except that the former has one more OH. DNAand RNA is the sugar, with 2-deoxyribose being replaced by the alternative pentosesugar ribose in RNA. The four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T).</span>
