What else can I help you with?
Is the white stringy material purely DNA or are there other cellular chemicals mixed in with the DNA?
The white stringy material often observed in cellular samples, such as during DNA extraction, typically consists of DNA mixed with other cellular components. Along with DNA, it may contain proteins, lipids, and RNA, as well as other nucleic acids and cellular debris. Thus, while DNA is a significant component, it is not purely DNA; the mixture reflects the complexity of the cellular environment from which it is derived.
Can DNA in an eukaryotic cell be found in cytoplasm?
No, in eukaryotic cells, DNA is found enclosed within the nucleus. The cytoplasm contains other cellular components like ribosomes, mitochondria, and the cytoskeleton. DNA is mainly responsible for storing genetic information and directing cellular functions.
What do cloroplast and mitocondria have that other organelles lack?
their own DNA
Why do you need RNA if you already have DNA?
RNA is needed because it serves as the messenger that carries genetic information from the DNA in the cell's nucleus to the ribosomes where proteins are made. RNA is also involved in other important cellular processes such as gene regulation and protein synthesis, making it a crucial component in the overall functioning of the cell despite the presence of DNA.
Does DNA replication occur at the ribosomes?
No. Chromosomes are found in the nucleus of the cell and these have sections which have codes. These codes are called genes. Ribosomes are found free in the cytoplasm or in the rough endoplasmic reticulum where they make proteins.

Where are the ribosomes in a DNA?
DNA is a molecule.It does not have Ribosomes.

What is a component of a cell?
Cell membranes are mostly lipids.
What cellular structure is responsible for liking together the amino acids?
A genetic code in the DNA which consists of nitrogen bases in the DNA.
What do chloroplast and mitochondria have the other organells lack?
They got circular DNA. They replicate themselves. Also have 70s ribosomes
If a toxin such as a bacterial toxin destroys ribosomes what cellular activity will be affected first?
Protein synthesis will be the cellular activity affected first if ribosomes are destroyed by a toxin. Ribosomes are responsible for translating mRNA into proteins, so their destruction would impair the cell's ability to produce essential proteins for various cellular functions.
How DNA linked to the role of ribosomes in a cell?
DNA contains the instructions to make proteins, and ribosomes are the cellular machinery that reads this information and synthesizes proteins accordingly. Ribosomes use the information encoded in DNA to assemble amino acids in the correct order, forming proteins that carry out various functions in the cell. Thus, DNA provides the genetic blueprint for protein synthesis, and ribosomes are the key players in translating this information into functional proteins.
Does algae have ribosomes?
I believe, as a biol. student, that chloroplasts contain their own genetic material (DNA and RNA) and ribosomes which has lead biologists to assume that chloroplasts evolved from ancient prokaryotic cells.yes they doYes, plants also contain ribosomes.yes they areYes.
What type of cell has enzymes DNA ribosomes and mitochondria?
The type of cell that has enzymes, DNA, ribosomes, and mitochondria is a eukaryotic cell. Eukaryotic cells have a defined nucleus that houses DNA, along with various organelles like ribosomes and mitochondria, which are responsible for different cellular functions such as protein synthesis and energy production.
