Answer: Histones and DNA have opposite charges -True
Acetylation of histones cancels their positive charge- True
Acetylated histones are more attracted to DNA - False
Acetylation creates binding sites for remodeling engines and other factors- True
Explanation:
It is widely found that acetylation of lysines leads to transcriptional activation. The modifications of histones such as acetylation affect the affinity of the histone for interacting proteins that control the transcriptional activity of chromatin,
which has led to the concept of a histone code.The positive charge on the histones is removed by acetylation, hence they decrease the interaction of histones with the negatively charged phosphate groups of DNA. As a result, the highly condensed chromatin is now transformed to a more relaxed structure and thereby higher level of transcription are achieved
Answer: Tapeworms live in almost all land, sea, and freshwater habitats Tapeworms also generally inhabit the intestines of humans and animals. They have a series of hooks on one end that they use to attach to the intestine to get nourishment from the host.
Explanation:
Most adult tapeworms live in the intestines of the final hosts, but a few species live in the body cavity.
