QUIZLET The contacts between the DNA and the histones of the nucleosome are: Group of answer choices a.Mainly between the R grou
ps of the histones and the phosphate backbone of the DNA. b.Mainly between the conserved histone folds and the phosphate backbone of the DNA helix. c.More prevelant in regions of the DNA that have tracts of GC pairs. d.These regions tend to bend more readily. e.Primarily between the DNA bases and the histone peptide backbone. f.None of the given answers.
b.Mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
Explanation: histones are protein that are found in eukaryote and they arrange the DNA into structural component called nucleosome. They are play a major role in gene regulation.
Histones are structures around which the DNA winds at the phosphate backbone of the DNA
Helix they compact DNA molecule and makes it fit into eukaryotic cell nuclei without this the unwounded DNA length would have be very long.
b. Mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
Explanation:
Histones are proteinous substances that are present in the chromatin of eukaryotic organisms.
The histones help to package or group DNA molecules in eukaryotic organisms into a structure that we refer to as chromosomes.
The contacts between the DNA and the histones of the nucleosome occurs mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
Answer:Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice. There are more particular instances (mutualism, symbiosis, etc.) where the connection is more local and direct.
