if the human genome contains by the latest estimate only 25000 -30000 genes, how can the immune system generate more than 100000000 different antibodies proteins and 100000000000 T cell receptors?
plz answers as soon as possible. thankyou

Because genes are not the same as protein encodings. One gene can contain many encodings.
There is also a difference between POTENTIAL encodings, which includes more molecules than have ever existed on Earth, and ACTUALLY encoded molecules, which is a far smaller set.

You have to remember that the primal goal and function of the body is to stay alive. So the body will create an infinate amount of cells that will help it survive.

the antibodiy strukture is not genetically encoded. They are produced at random, and the ones that work are kept.
Its like I can tell you how to toss a dice, but I cant tell you how to toss a six.
