The complex of DNA and proteins that forms the eukaryotic chromosome. which of the following best describes the term ‘chromatin’? a ladder of protected fragments about 200 bp apart. Analysis of the DNA component by gel electrophoresis would have revealed.
What is a chromatin quizlet?
Chromatin. An organelle which forms chromosomes during cell division. Consists of DNA, RNA, and proteins. This organelle can have different structures (e.g.an “x” or lines spinning).
What is chromatin also known as?
The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. The formed protein/DNA complex is called chromatin. The basic structural unit of chromatin is the nucleosome.
What is the function of 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 are the 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.
What is the difference between DNA and chromatin?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.
|Difference between Chromosomes and Chromatin|
|Composed of nucleosomes||They are condensed chromatin fibers|
What are microvilli and what is their purpose quizlet?
Microvilli increase the surface area of the cell, usually for absorption. The cells lining the small intestine have microvilli for that purpose. Cilia wave around to help move the external medium.
