<span>Proteins that are involved in the packaging of eukaryotic chromosome into "beads" called nucleosome are histones.</span>
A nucleosome is a segment of DNA wound in sequence around eight proteins called histones. Together the DNA and the histones form "beads"
A nucleosome is the basic unit of DNA packaging in eukaryotic cells.
Most of the brain's excitatory ionotropic synapses use the neurotransmitter glutamate.
The best correct answer is C.

<span>Meiosis is the process of cell division that reduces the chromosome number by half. During the process two phases (two nuclear divisions) occur: Meiosis I and Meiosis II. Meiosis I is the phase of reduction and Meiosis II is the division. So, if a cell under a microscope shows two daughter cells and they aye haploid than this is the stage Meiosis II, in which the cell is divided into two daughter cells.</span><span />
