Food doesn't taste good during common cold. why?

When we're sick, our noses are often blocked with mucus. Also, the tissues inside our nose can become swollen and inflamed. This prevents us from smelling properly. Because your sense of smell is so tied to your sense of taste, if you can't smell things properly, you won't be able to taste them properly, either.

Rna polymeras should attache to the promoter.

Ithink its false. hope this : )
