You mean that the DNA of the cells have been damaged so mush that it stops dividing, and when a lot of them are dying at the same time, the tissues are losing its phsiological function, and age? BUt why do you say for much of the aging?
What genes cause aging, most people think shortening of telomeres is the main reason of aging, but I know there are more than that, like Klotho, Methuselah. But which fews are more important than others, and what else are there?
its not a class assigment and need to be that detailed... just a short answer would do, the 2nd article is massive, so it is a protase, but how does it help the virus?
Do you know why potyviruses generate inclusion bodies as part of a translational strategy?
I tried to find it on the web, but not many of them are that specific and hard to understand.
thanks
