Q. Why do cells have to undergo cell cycle process?
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.

Q. How does a cell enter the cell cycle?
The whole process is called the cell cycle and consists of four main phases. Entry to the cycle is made in Gap 1 (G1) phase and this is followed in sequence by a DNA synthesis (S) phase, Gap 2 (G2) phase, and Mitosis (M). cells that can divide again immediately enter the G1 phase of a new cell cycle.
Q. Can a cell multiply?
Meiosis and Mitosis: Mitosis is when a cell multiplies by spliting into two, to do this there must be enough nutrients and the cell must have undamaged DNA. The cell multiplies its DNA and then through Prophase, Metaphase, Anaphase, and Telophase.
Q. Who benefited from HeLa cells?
Over the next 60+ years, thousands of scientists will author over 110,000 research publications involving HeLa cells. Scientists discover that HeLa cells are found to be an effective tool for growing large amounts of poliovirus, the cause of Poliomyelitis, or polio disease.
Q. How do HeLa cells stay alive?
Under the right conditions, HeLa cells form an immortal cell line; they divide indefinitely. Remember that HeLa cells were grown from a tissue sample from Lacks’ cervical tumor. Just like the cancer grew and spread quickly through Lacks’ body, HeLa cells grow and spread quickly in vitro.
Q. Where did HEK 293 come from?
HEK 293 cells were generated in 1973 by transfection of cultures of normal human embryonic kidney cells with sheared adenovirus 5 DNA in Alex van der Eb’s laboratory in Leiden, the Netherlands.
Q. What is the difference between HEK293 and HEK293T?
HEK293 – The HEK293 line is the original line established from a primary embryonic human kidney and transformed with sheared human adenovirus type 5 DNA. HEK293T – HEK293T is a HEK293 variant that expresses a temperature-sensitive allele of the SV40 T antigen.
Q. Are HEK293 cells used in food?
THERE ARE NO FOOD PRODUCTS CONTAINING ABORTED FETAL MATERIAL – NOR HAS THERE EVER BEEN!” The situation for anti-ageing creams that are manufactured using cell lines derived from fetuses is essentially the same story, and it is likely that these claims of fetal material in perfumes are the same as well.
