What best describes the role of mrna in gene expression?

I have following options with me
a. Stores the genetic code in the nucleus. 
b. Splits the DNA molecule into two strands. 
c. Carries an amino acid to the ribosome. 
d. Copies the genetic code from the DNA molecule and carries it to the ribosome.
according to these options my answer is D.
hope this will help:) 

The genetic information from the DNA is transferred to mRNA in a process called transcription. Then an enzyme called RNA polymerase II catalyzes the making of pre-mRNA. Then it is processed to form a mature mRNA. Then it becomes a single stranded mRNA and it is translated in a protein molecule.

Ifound this on google “according to the findings, a foramen magnum positioned toward the base of the skull is found not only in humans, but in other habitually bipedal mammals as well.” i hope this you for what your looking for

From our previous experiment, we examined how many drops a penny can hold - and place drops of salt water on the penny after recording 5 trials each, take the average of each solution.
