What else can I help you with?
Do all cells contain DNA?
No, not all cells contain DNA. Red blood cells, for example, lose their nucleus and DNA as they mature to make space for more oxygen-carrying hemoglobin. Additionally, some viruses do not have their own DNA and rely on host cells to replicate.
Is this statement true or false At some time during their lives all cells must contain DNA.?
True. All cells must contain DNA at some point in their lives, as DNA carries the genetic information necessary for cellular functions and replication. Even cells that do not have a nucleus, like prokaryotes, still contain DNA in the form of plasmids or a single circular chromosome. Additionally, during the cell cycle, all cells undergo processes that involve the presence of DNA for growth and division.
At some time during their lives all cells must contain DNA. is this true?
At some time during their lives, all cells must contain DNA.
What if your skin cells have the exact same DNA as your blood cells?
This would be normal. All body cells have the same DNA, including blood cells, at least at some point during their life cycles. Mature red blood cells do not contain DNA because they do not have cell nuclei. But when red blood cells are first formed, they do have a nucleus with DNA identical to the rest of the body cells.
Do DNA have all cells?
No. Some cells do not in fact have DNA, probably because of the lack of a nucleus. For example, mature red blood cells (erythrocytes) do not contain a nucleus or DNA.
Do plants cells contain DNA why or why not?
Yes, plant cells contain DNA. They contain it because DNA is necessary to the cells so that they can carry the instructions to carry out life functions and reproduce.Nucleus and chloroplasts
Do tears contain DNA?
Tears may contain loose cells (which contain DNA), but it is mostly just water and dissolved salts.
Is it true or false that prokaryotic cells contain more DNA than eukaryotic cells?
False. Eukaryotic cells generally contain more DNA than prokaryotic cells. Eukaryotic cells have their DNA enclosed within a nucleus, whereas prokaryotic cells have their DNA located in the cytoplasm.
How valuable are red blood cells in DNA typing?
Red blood cells do not contain a nucleus, which means they lack DNA. As a result, red blood cells are not useful for DNA typing. Instead, white blood cells, which do contain DNA, are typically used for DNA profiling and typing in forensic analysis.
Does water contain DNA?
No, water does not contain DNA. DNA is a molecule found in the cells of living organisms, not in water.
What structures do cells have?
Cells are surrounded by a barrier called a cell membrane and at some point in their lives they contain the molecule that carries biological information (DNA). The structures that all cells have are ribosomes, plasma membrane, cytoplasm, and genetic material.
Which cells have DNA as their genetic material?
Haploid cells like sperm cells,ova,bacteria
