What is chief role of the nucleus in a cell?
The nucleus contains the DNA, which has the instructions for the production of functional products (i.e. proteins). Therefore the main role of the nucleus is to control the functions of the cell.
What is th role of dnazol in dna extraction?
DNAzol is a reagent used in DNA extraction to lyse cells by disrupting the cell membrane and nucleus. It helps release DNA from the cells and proteins, allowing for subsequent separation and purification of the DNA. DNAzol also helps protect the DNA from degradation during the extraction process.
Are proteins regulators of cell division?
Yes, proteins play a crucial role in regulating cell division. Proteins such as cyclins and cyclin-dependent kinases (CDKs) form complexes that control the progression of the cell cycle by activating or deactivating various checkpoints. These proteins regulate key events like DNA replication and chromosome segregation to ensure proper cell division.
Do genes proteins or DNA polymerase control cell division?
Cell division is primarily controlled by genes that encode various proteins, including cyclins and cyclin-dependent kinases (CDKs), which regulate the cell cycle. DNA polymerase plays a critical role in DNA replication during cell division but does not directly control the process itself. Instead, it is the interactions and activities of these proteins, guided by the genetic information in DNA, that orchestrate the complex regulatory mechanisms of cell division. Thus, genes and their protein products are key regulators in this process.
How does DNA function in a living cell?
DNA serves as the genetic blueprint of a cell, containing the instructions for building and maintaining an organism. It is transcribed into RNA, which is then translated into proteins, the workhorses of the cell. DNA replication ensures proper cell division and inheritance of genetic material.
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 role do proteins in enabling the enormous amount of DNA in a eukaryote cell to fit into the nucleus and what are those proteins called?
DNA that is not being "used" by the cell is wrapped up around proteins called histones.
What proteins are associated with DNA in a cell?
Histones are the main proteins associated with DNA in a cell. These proteins help to package and organize DNA into chromatin, which plays a role in gene regulation and overall genome structure. Other DNA-binding proteins, such as transcription factors, also interact with specific regions of DNA to regulate gene expression.
What is the Role of the DNA molecule in cells?
DNA is much like the "brain" of the cell. It contains genes that produce proteins through transcription (DNA--->RNA) and translation (RNA---->protein). Proteins are what give a cell its function (i.e. turns it from a generic cell into a muscle cell). in a nutshell, it basically tells the cell what to do.
What does a DNA do for a cell?
DNA has the instructions for making all of the cell's proteins. The proteins handle everything else. So in this way DNA directs all the cell's activities.
Role of chloroform in plasmid isolation?
Chloroform is commonly used in plasmid isolation to separate different components in a cell lysate, such as proteins, RNA, and DNA. It helps to denature proteins and disrupt cell membranes, allowing for the separation of plasmid DNA from other cellular components. Chloroform also aids in the removal of lipids and other contaminants during the purification process.
Role of chloroform in DNA isolation?
Chloroform is used in DNA isolation to separate the DNA from other cellular components like proteins and lipids. It helps in the denaturation of proteins, disrupting their structure and allowing the DNA to separate into the aqueous phase. Chloroform aids in the extraction and purification of DNA from the sample.
Why Triton x is used in DNA extraction by phenol chloroform method?
Triton X is a nonionic surfactant that disrupts cell membranes, allowing phenol and chloroform to access and denature proteins in the cell. This helps in separating DNA from proteins and other cellular components during the DNA extraction process.
Chromatin is a mixture of?
Chromatin is a mixture of DNA and proteins that make up the genetic material within the nucleus of a cell. It condenses to form chromosomes during cell division and plays a crucial role in regulating gene expression.
What is chief role of the nucleus in a cell?
The nucleus contains the DNA, which has the instructions for the production of functional products (i.e. proteins). Therefore the main role of the nucleus is to control the functions of the cell.

DNAzol is a reagent used in DNA extraction to lyse cells by disrupting the cell membrane and nucleus. It helps release DNA from the cells and proteins, allowing for subsequent separation and purification of the DNA. DNAzol also helps protect the DNA from degradation during the extraction process.
What is the DNA material within a cell that wraps around proteins called?
The DNA material within a cell that wraps around proteins is called chromatin. Chromatin is composed of DNA and proteins, mainly histones, which help in compacting and organizing the DNA within the cell nucleus.
