Cross-resistance

Cross-resistance

(Science: immunology, microbiology) immunologic resistance to the pathogenic effects of a microorganism because of previous exposure to another species or type having cross reactive antigens.

this phenomenon is seen in microbes that acquire resistance to one drug through direct exposure and turn out to have resistance to one or more other drugs to which it has not been exposed. Cross-resistance arises because the mechanism of resistance to several drugs is the same and arises through the identical genetic mutations.

Ligase reaction problem

... it is enough base lenght for ligase reaction via thermostable ligase in 63 C (Protocol: 5 cycle at 95 C-30 s and 63 C-4 min) I think I take cross reaction because of this dimer but I am not sure. Is it possible to discard this short undesired dimers in the reaction. Thank you cross.jpg

Re: need help with some home work

I agree with Athira here. Your first two answers are wrong. You can visualize a cross. aa x aa will never give Aa genotype for a baby. AA X AA will never give a Aa baby. oN THE FACE of it, if you have a parent Aa cross with AA, you should get a baby with either ...
