What is the generalized photosynthetic equation?
2n CO2 + 2n H2A + photons → 2(CH2O)n + n O2 + 2n A
What are the molecular weights of histone proteins?
The molecular weights of core histone proteins are approximately as follows: H2A (13 kDa), H2B (15 kDa), H3 (15 kDa), and H4 (11 kDa). However, these values can vary depending on post-translational modifications and histone variants.
A nucleosome contains how many histones within its core?
A nucleosome contains two copies each of four core histone proteins: H2A, H2B, H3, and H4.
Significance of nucleosome?
Part of Chromatin. Smaller units made of DNA & histone octamers (8). 2 of each: H2A, H2B, H3, H4, all attached to the larger H1.
What is a nucleosome and what organic component is it primarily composed of?
Chromatin composed of tetramer of histones 2 copies each of Histone H2A, H2B, H3 and H4. DNA is bound on the nucleosome and uses 147 basepairs of DNA.
What composed of a granular cluster of eight proteins?
The composed of a granular cluster of eight proteins is a histone octamer. This structure consists of two sets of four core histone proteins (H2A, H2B, H3, and H4) that form a cluster around which DNA is wrapped to create a nucleosome.
What do you get if you mix iron and hydrochloric acid?
Assuming iron II.Fe + 2HCl --> FeCl2 + H2A salt, iron II chloride ( also known as ferrous chloride ), and hydrogen gas.
In chemistry why is it when making salt it is plus water at the end and then sometimes plus hydrogen how can you determine whether to write it with water at the end or hydrogen please help?
The reaction of an alkali metal with water is violent and release hydrogen:2 Na +2 H2O = 2 NaOH + H2A neutralization reaction is:NaOH + HCl = NaCl + H2O
Where can you buy baby phat cloths in Montreal?

What is histone core?
A Histone Core is a group of Histone Proteins, mainly used in eukaryotes to package DNA strands into Nucleosomes. (Think of it like a spool for the DNA to wrap around, to be easily stored on a shelf)
What are histone?
HistonesHistones are proteins that aid in the organization of DNA into chromosomes. There are four types of histones found in chromatin: H2A, H2B, H3, and H4. Two of each histone comprise a protein core, a nucleosome, which DNA wraps around twice. What results is a "bead on a string" model in which the nucleosomes are the beads and the linker DNA binds them together. Another characteristic of histones are the protein tails that extend outward from the "bead." The tails and the degree of their acetylation is an important factor in gene expression.

What is the formula for Diprotic acid?
A diprotic acid is an acid that can donate two protons (hydrogen ions) per molecule in an aqueous solution. The general formula for a diprotic acid is H2A, where A represents the anion or negative ion part of the molecule.
