What is the function of chromatin quizlet?

What is the function of chromatin?

Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are proteins called histones. They act as packaging elements for the DNA. The reason that chromatin is important is that it’s a pretty good packing trick to get all the DNA inside a cell.

What is the function of the chromatin quizlet?

The primary functions of chromatin are 1) to package DNA into a smaller volume to fit in the cell, 2) to strengthen the DNA to allow mitosis, 3) to prevent DNA damage, and 4) to control gene expression and DNA replication. -The DNA molecule is packaged into thread-like structures called chromosomes.

What is a chromatin quizlet?

Chromatin. -Genetic material in a non-dividing cell. -the material of which the chromosomes of organisms are composed. It consists of protein, RNA, and DNA. -Unwound DNA.

What is the function of the chromatin for kids?

What is the Function of Chromatin? Chromatin is a way for DNA to take up less space in the nucleus of the cell. It also keeps the nucleus organized when the cell divides to form two cells. When DNA is stored as chromatin it is protected, making it safer than if it were left uncoiled in the cell.

What is the function of chromatin in an 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.

What is called 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 is the function of a vesicle quizlet?

– vesicles: small membrane bound sac that stores & transports substances to different locations in a cell; at the plasma membrane they discharge their contents as secretions, a process called exocytosis because substances exit the cell. Describe the structure and function of lysosomes and peroxisomes.

What are the main functions of DNA quizlet?

Lecture 2 – Functions of DNA

  • to store information.
  • to replicate faithfully (preserve information)
  • to have the ability to mutate (to add variability to information)

What is the function of vacuole quizlet?

Vacuoles are membrane-bound organelles used to store substances within the cell. the tonoplast or central vacuole of plant cells retained water to give the plant cell rigidity and support. Vacuoles also serve as storage sites for materials used by the cell, such as some pigments, as well as for toxic substances.

What are characteristics of chromatin?

Chromatin is composed of DNA and histones that are packaged into thin, stringy fibers. These chromatin fibers are not condensed but can exist in either a compact form (heterochromatin) or less compact form (euchromatin). Processes including DNA replication, transcription, and recombination occur in euchromatin.
