DNA contains the genetic information that determines the characteristics and functions of cells. It serves as a blueprint for making proteins, which are essential for various cellular processes such as growth, development, and repair. DNA also plays a crucial role in cell division and replication to ensure the faithful transmission of genetic material to daughter cells.

What is the opposite of DNA?
The opposite of DNA would be non-DNA, such as RNA, which is another nucleic acid that plays a role in protein synthesis and gene regulation in cells.
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.
Histones are proteins that?
Histones are proteins that help organize the DNA in our cells by forming complexes called nucleosomes. These nucleosomes play a crucial role in regulating gene expression and DNA packaging.
Why onion is suitable for DNA extraction?
Onions have cells with a relatively high DNA content, making them a suitable source for DNA extraction. Additionally, onions contain enzymes that help break down cell walls and release DNA, making extraction more efficient. Onion DNA is also relatively stable and less prone to degradation, making it easier to work with in the lab.
What is the role of urea in DNA extraction?
Urea is often used in DNA extraction to denature proteins and disrupt cellular membranes. This helps release DNA from the cells and allows it to be isolated for further analysis. Urea also helps to maintain the stability of the DNA during the extraction process.

A natural polymer that is the present in all living cells and that plays a role in a protein synthesis?
The natural polymer present in all living cells that plays a role in protein synthesis is RNA (ribonucleic acid). RNA is responsible for carrying the genetic information from DNA to the ribosomes where proteins are synthesized. It acts as a messenger between DNA and the protein-making machinery in the cell.
Dna has the instructions for making a cells?
Correct, DNA contains the genetic instructions for building and operating cells. These instructions determine an organism's characteristics and functions by encoding specific proteins and regulating their production. The process of expressing these instructions is tightly controlled and essential for the functioning and survival of the cell.
Histones are proteins that?
Histones are proteins that help organize the DNA in our cells by forming complexes called nucleosomes. These nucleosomes play a crucial role in regulating gene expression and DNA packaging.

What is the role of calcium chloride in transformation?
Calcium chloride is used in transformation to destabilize the cell membrane, making it more permeable to foreign DNA. This helps in improving the uptake of the DNA by the cells, leading to successful transformation.
Making DNA from DNA is called?
DNA synthesis, properly known as Replication.
Does DNA have cells?
no. Cells have DNA not the other way around
Can DNA testing be carried out on red blood cells alone?
No, DNA testing requires a white blood cell sample because red blood cells do not have a nucleus, which is necessary for DNA analysis. White blood cells contain a nucleus where DNA is located, making them suitable for DNA testing.
Which statement best describes the relationship among proteins DNA and RNA?
Proteins are synthesized based on the information encoded in DNA through the intermediary molecule RNA. DNA contains the genetic instructions for making proteins, while RNA serves as a messenger to carry these instructions from the DNA to the protein-making machinery in the cell. Together, these molecules play essential roles in the central dogma of molecular biology, where genetic information flows from DNA to RNA to proteins.
