What is gravity and how does it influence objects?

Gravity is the force by which a object or other body draws objects toward its center.

Explanation:

If I toss a ball into the air gravity will influence it and bring it towards its center, in this case the ground.

1.  The enzyme dicer cleaves dsRNA to form

small interfering RNA (siRNA).

2.  The siRNA binds to a special protein,  

which degrades one strand.

3. One strand of siRNA associates with the

protein to form an RNase complex.

4. The RNase complex binds to a specific

mRNA and degrades it.
