WebApr 15, 2024 · At the end of the growing seasons, crop diversification increased prokaryotic richness and Shannon diversity in response to N addition, with a greater increase in the conventional N. At conventional N supply, prokaryotic co-occurrence networks revealed a much denser and complex structure in the diversified system. WebDinoflagellates are very divergent eukaryotes in terms of how they package their DNA. Their chromosomes are packed in a liquid-crystalline state. They have lost many of the conserved histone genes, using mostly dinoflagellate viral nucleoproteins (DVNPs) or bacteria-derived dinoflagellate histone-like proteins (HLPs) for packaging instead.

11.5: DNA Packaging in Eukaryotes and Prokaryotes

WebEukaryotic DNA is bound to basic proteins known as histones to form structures called nucleosomes. The chromatin (the complex between DNA and proteins) may undergo some chemical modifications, so that the DNA may be able to slide off the proteins or be accessible to the enzymes of the DNA replication machinery. WebEukaryota, whose members are known as eukaryotes (/ j uː ˈ k ær i oʊ t s,-ə t s /), is a diverse domain of organisms whose cells have a nucleus.All animals, plants, fungi, and many unicellular organisms are eukaryotes.

DNA (deoxyribonucleic acid) is the genetic material of living organisms. In humans, DNA is found in almost all the cells of the body and provides the instructions they need to grow, function, and respond to their environment. When a cell of the body divides, it will pass on a copy of its DNA to each of its daughter cells.
