How does a double integral gives area ? I cannot imagine it

Advanced Placement (AP)
1 answer:
Arisa [49]3 years ago

In general, double integrals calculate volume (or can be interpreted as such).

That is:

\displaystyle \iint_{A} f(x,t)dA 

gives the net volume under the function f(x,y) and the x-axis.

However, if f(x,y)=1, then the height of the solid is 1 and its volume is equivalent to its base area.

Explanation:

The luciferase mRNA is moved to its similar protein in the ribosome which is seen in the cytoplasm of the cell.

The chain of ribosome sits on the mRNA and forms a structure In the cytoplasm,called a polysome. this is useful in the fast synthesis of protein. The three-nucleotide genetic code in the mRNA which is being studied by the ribosome orders the right placement  of amino acids through particular tRNA.
