Your question: What does chromatin produce?

Chromatin fibers are coiled and condensed to form chromosomes. Chromatin makes it possible for a number of cell processes to occur including DNA replication, transcription, DNA repair, genetic recombination, and cell division. People often confuse these three terms: chromatin, chromosome, and chromatid.

Does chromatin produce energy?

These proteins are called histones, and the resulting DNA-protein complex is called chromatin. … Thus, within the nucleus, histones provide the energy (mainly in the form of electrostatic interactions) to fold DNA. As a result, chromatin can be packaged into a much smaller volume than DNA alone.

What does chromatin condense into?

During cell division, chromatin condenses to form chromosomes. Chromosomes are single-stranded groupings of condensed chromatin. During the cell division processes of mitosis and meiosis, chromosomes replicate to ensure that each new daughter cell receives the correct number of chromosomes.

Is DNA made of chromatin?

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. … Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA wrapped around eight proteins called histones.

What happens during chromatin?

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be “opened” so that specific genes are expressed. If the DNA strand in a single human cell were stretched out, it would measure several meters in length.

What is the function of chromatin in animal cell?

Its functions are to package DNA into a smaller volume to fit in the cell, strengthen the DNA to allow mitosis and meiosis, and serve as a mechanism to control expression. The chromatin is found within the nucleus of eukaryotic cells and the cytoplasm of prokaryotic cells.

How does chromatin control gene expression?

In eukaryotes, the tight or loose packaging of the genes in chromatin (DNA plus specific proteins) can control whether the genes can be expressed to form their encoded product. DNA itself can be methylation and that also regulates gene expression, generally to turn off the gene. …
