Cell regulation/death

... require growth hormones and other signals to proliferate and live. If they lack them, or they receive signal to die off, they undergo the PCD. The telomeres are problem, but they measure for all the cells about the same number of divisions, so there could be no selectivity. Cancer cells are usually ...

Cell regulation/death

... you guys could give me a concrete answer for this: I want to know how the body regulates cells, I did some research of my own and I know a bit how telomeres work and that cells get the signal to die if the telomeres are gone so the DNA wouldn't get damaged, but in my believes it can't be the only ...

Telomere and DNA replication

... and one daughter strand 5'_________3'(parent strand - complete telomere) 3'_________5'(daughter stand) The daughter stand is shorter owing to lost telomeres. I have discoerved, from private research, that telomere binding proteins prevent exonucleases degrading the sticky ends of the parent strand. ...

telomer

... have protein and RNA component. RNA component acts as primes to the strand. but it gets shorter as the replication cycle. as cells age, the telomeres get shorter! shortest telomere or lack of it, signals apoptosis. Cancer cells avoids apoptosis, by synthesis of more and more telomeres which ...

Bio Research Paper Writing

... telomere function. Normally, telomerase isn’t active in most cells (which is an evolutionary advantage against cancer) and the shortening of the telomeres eventually results in ends that is recognised as double stranded breaks (DBS) which tiggers chromosomal break-fusion-bridge cycles that result ...
