What else can I help you with?
Chromatin contains proteins called?
Histones are the main proteins in chromatin, histones are a group of five small basic proteins in the nucleus.
What is the molecule surrounding DNA?
The molecule surrounding DNA is called histones. Histones are proteins that help organize and package DNA into chromatin, which is the complex structure that makes up chromosomes. Histones play a crucial role in regulating gene expression and maintaining the structure of DNA within the cell.
What role do histones play in a cell?
DNA strands are wrapped around the histones. In order for DNA to be accessible, histones must be modified (acetylation). If the histones are "protected" at a particular locus from modification, the genes are silenced and cannot be expressed.
Histones are found in?
Histones are found in the cell nucleus, where they help package and organize DNA into structures called nucleosomes. Nucleosomes consist of DNA wrapped around histone proteins, forming the basic unit of chromatin. Histones play a key role in regulating gene expression and chromatin organization.
What role do proteins play in enabling the enormous amounts of DNA in the eukaryote cell to fit into the nucleus and what are the proteins called?
DNA that is not being "used" by the cell is wrapped up around proteins called histones.
What protein does DNA wrap around?
DNA wraps around histone proteins to form chromatin, which helps to compact and organize the genetic material within the cell nucleus. Histones play a crucial role in regulating gene expression and overall DNA function.
What protein has no signal sequences?
Histones are proteins that bind to DNA in the cell nucleus and play a role in regulating gene expression, but they do not contain signal sequences for targeting to specific cellular compartments.
What is the histone part?
Histones are the protein molecules around which DNA is tightly coiled in chromatin. They help organize and condense DNA within the cell's nucleus, allowing for efficient packaging of genetic material. Histones play a key role in gene regulation and overall chromosomal structure.
Does histones and DNA molecules relate to each other?
Histones are a part of DNA. Histones are actually 8 molecule of proteins joined together and the DNA strand wraps around the the histone in a circular manner. Histones are present on the DNA strand at regular intervals.
The proteins which complex with DNA producing the beads on a string or nucleosomes are called?
Histones are the proteins that complex with DNA to form nucleosomes, which are the repeating units that make up the structure of chromatin in eukaryotic cells. Histones play a crucial role in packaging DNA and regulating gene expression.
To help with biology homework what are histones?
Histones are proteins found in eukaryotic cell nuclei. They are high in alkaline. Histones package and order the DNA into units that are called nucleosomes.
What is the relationship between DNA and histones in the process of gene expression?
DNA and histones are closely related in the process of gene expression. DNA is wrapped around histones to form chromatin, which helps regulate gene expression by controlling access to the DNA. Histones can modify the structure of chromatin, making certain genes more or less accessible for transcription. This interaction between DNA and histones plays a crucial role in determining which genes are expressed in a cell.
