A triploid cell is the structure form during angoisperm fertilization. The cell are created in the process known as double fertilization into the endosperm which is mostly are polyploid. These are typicallly triploids that is they contain three sets of chromosomes but they varies widely from diploid (2n) to 15N.
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
<span>The molecular clock has been useful to determine the phylogenetic relationships of species based on the assumption that they cannot be compared to non molecular methods such as comparative anatomy. The molecular clock helps us discover organisms that have a little common traits or features between evolutionary relationships.</span>
The answers would be vacuole
