What is chromatin in chromosome?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus.
What are chromosomes vs chromatin?
The major difference between chromatin and chromosomes is that chromatin is composed of DNA and histones that are packed into a fiber whereas a chromosome is a single-stranded form of condensed chromatin. The chromosome structure is based on the fine fiber of chromatin.
Where is the chromatin in a chromosome?
the nucleus
Chromatin is located in the nucleus of our cells Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells.
What is chromatin and its functions?
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.
What is a chromatin simple definition?
Chromatin refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms. Many of the proteins — namely, histones — package the massive amount of DNA in a genome into a highly compact form that can fit in the cell nucleus.
What is 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 the difference between chromatin and chromosomes quizlet?
What is the difference between chromatin, chromatids, and chromosomes? Chromatin is the DNA and proteins that make up a chromosome. Chromosomes are the separate pieces of DNA in a cell. And Chromatids are identical pieces of DNA held together by a centromere.
What is a chromatin kid definition?
Kids Encyclopedia Facts. Chromatin is the complex combination of DNA and proteins that makes up chromosomes. It is found inside the nuclei of eukaryotic cells. Chromatin is divided into heterochromatin (condensed) and euchromatin (extended) forms.
What is a chromatin quizlet?
What is chromatin made of?
What consist of each bead of chromatin?
nucleosomes
In general, there are three levels of chromatin organization: DNA wraps around histone proteins, forming nucleosomes and the so-called beads on a string structure (euchromatin). Multiple histones wrap into a 30-nanometer fiber consisting of nucleosome arrays in their most compact form (heterochromatin).
