In biology, histones are highly basic proteins abundant in lysine and arginine residues that are found in eukaryotic cell nuclei and in most Archaeal phyla.

15 нояб. 2019 г. · In almost all eukaryotes, histone-based chromatin is the standard, yet in bacteria, there are no histones. So, how and why have histones become ...

Although histone-fold proteins can be found in several bacteria (Hocher et al. 2023), eukaryotic histones most probably have archaeal ancestry, like many other ...

Histone modification affords the elaborate control of gene expression required by the vastly expanded cellular DNA complement of eukaryotes (Figure 3, Box 1).

2 мар. 2024 г. · Its constituent parts, the four core histones (H3, H4, H2A, H2B), are universal to eukaryotes.

Both eukaryotic cells and Archaea have histones because they need to efficiently package their DNA. This packaging allows the DNA to fit within the cell.

7 мая 2019 г. · In eukaryotes, histone modifications link gene expression to the physiological state of the cell via carbon-, energy-, and nitrogen-sensing ...

10 мая 2021 г. · Histones, as linchpins of the apparatus for gene regulation, play a role in almost every function of eukaryotic cells. “In order to get complex, ...

Histones are found mostly in eukaryotes. Chromosomes contain a specific kind of protein. Histones are proteins that attach to DNA, form chromosomes, and ...
