Chromatin has several functions, the main one being to condense the six feet of DNA in every cell down to fit inside the nucleus. The chromatin is also responsible for helping transcribe RNA, help prevent the DNA from being damaged while being compacted inside the nucleus, and assist in gene expression.
There are two basic types of chromatin, the euchromatin and the heterochromatin. The euchromatin is involved in the transcription of RNA, which helps produce proteins for the production of energy. These chromatins are more diffused than other types. The heterochromatin holds the genes that are silent, or not expressed during the gene expression. The DNA held in the heterochromatin is referred to as being genetically inactive.Learn More
Chromatin is a combination of different things that make up chromosomes. This combination includes DNA, histone and other proteins. Chromatin can be found in eukaryotic cells in the nuclear envelope.Full Answer >
Chromatin and chromosomes are both structures of DNA, but chromosomes are condensed chromatin. DNA exists as chromatin a majority of the time so that the DNA is accessible to proteins for transcription and proteins can be made during the process of translation. Chromatin is condensed into chromosomes during mitosis to ensure that replicated genetic information is divided equally between the two resulting daughter cells.Full Answer >
Chromatin is made of nucleic acids, such as DNA or RNA, and proteins. During cell division, chromatin condenses to form chromosomes. Eukaryotic and prokaryotic cells differ in where chromatin is housed. In eukaryotes, it is located in the nucleus and in prokaryotes, it is located in the nucleoid.Full Answer >
During the prophase stage of cell division, chromosomes begin to condense, coil and fold, making them visible under a light microscope. When the duplicated chromosomes continue to coil, the chromosomes are shortened and thickened to a more visible state.Full Answer >
