Cyclins
Proteins like histones help condense chromosomes by wrapping DNA around them to form nucleosomes. This compacts the DNA into a more condensed structure, making it easier to fit inside the cell's nucleus and regulate gene expression.
Histones are the main proteins in chromatin, histones are a group of five small basic proteins in the nucleus.
The genetic material that is tightly wrapped around proteins is called chromatin. Chromatin is made up of DNA and proteins called histones, and it helps to condense the DNA into a compact form that can fit inside the cell nucleus.
Some of the things inside the nucleus where proteins are made are ribosomes, nucleoplasm, and nuclear pore.

Internal Regulators Proteins that respond to events inside the cell are called internal regulators. Internal regulators allow the cell cycle to proceed only when certain processes have happened inside the cell. For example, several regulatory proteins make sure that a cell does not enter mitosis until all its chromosomes have been replicated. Another regulatory protein prevents a cell from entering anaphase until all its chromosomes are attached to the mitotic spindle.

Internal regulators are proteins that respond to activity within a cell.
Histones
Proteins are found in cells. Proteins are a macromolecule.
G proteins are signaling molecules that help transmit signals from outside the cell to the inside, activating various cellular responses. They act as molecular switches that regulate the activity of enzymes and other proteins involved in cellular processes.
The protoplasm inside the nucleus is called nucleoplasm. It contains various molecules such as DNA, RNA, and proteins that are necessary for genetic processes and cell function.
The dark rounded bodies found inside phloem cells typically are protein bodies or P-proteins, which play a role in sieve element sealing and defense against pathogens. These P-proteins help regulate the flow of sap within the phloem tubes.

Ribosomes are the small grain-like bodies inside cells that produce proteins. They are responsible for translating the genetic code from messenger RNA into the amino acid sequences that make up proteins.

Chromosomes are made up of DNA coiled around proteins called histones. The DNA and histone proteins together form a structure called chromatin, which helps pack the genetic material efficiently inside the cell nucleus.
