What do cells need to do before they undergo mitosis?
Replication of DNA
Why does your body undergo DNA replication?
So as to grow and sustain your life.
Which phase do cells undergo a round of DNA replication?
Cells undergo a round of DNA replication during the S phase of the cell cycle. This is when the cell duplicates its DNA to prepare for cell division.
Do Prions require a host to survive?
Prions do not require a host to survive in the traditional sense, as they are misfolded proteins that can exist independently in the environment. They can remain stable and infectious outside of a host for extended periods, often found in contaminated materials. However, to propagate and cause disease, prions need to interact with normal proteins in a host to induce misfolding. Thus, while they can exist outside a host, they need a host for replication and pathogenicity.
Time required for DNA replication in E. coli?
E.coli will take 15 to 20 minutes to undergo the entire cell division cycle exact time for DNA replication is not known.
During which phase of the cell cycle does DNA undergo replication, whether it is during interphase, mitosis, or meiosis?
DNA undergoes replication during the S phase of interphase in the cell cycle.
How do viroids and prions compare with viruses?
Viroids are small infectious agents consisting of a short, single-stranded RNA molecule, while prions are misfolded proteins without nucleic acid. In contrast, viruses are composed of genetic material (DNA or RNA) surrounded by a protein coat. Viroids and prions lack the ability to replicate independently, unlike viruses which require a host cell for replication.
Why do you call the nucleus the brain of the cell?
It has genetic material called DNA which undergo different functions such as replication, transcription, translation
Is DNA found in all prions?
No, DNA is not found in any prions. Prions are just protein - they don't contain a nucleic acid.
Can you kill prions by sterilization?
No, cooking does not destroy or disable prions. If you were able to cook a meat that contains prions to the point where the prions were disabled, the meat would be rendered inedible.You can use chemicals mixed with heat to destroy prions, but that's not a process you would want to subject your food to.
How does the interphase set up the prophase?
Before a cell can undergo Mitosis (in which prophase is the first stage) It must first undergo synthesize certain proteins, produce organelles for the daughter cells, and arrange the structures for cell division. It also needs to undergo DNA replication.
Which processes do not involve the replication of chromosomes?
Processes that do not involve the replication of chromosomes include meiosis and binary fission. In meiosis, chromosomes undergo recombination and separation without additional replication after the initial round. Binary fission, seen in prokaryotes, involves the division of a cell into two without the replication of its chromosomes before division. Additionally, processes like transcription and translation focus on gene expression rather than chromosome replication.
