A Form of RNA Carries Information from the DNA in the Nucleus

question 57

Multiple Choice

A form of RNA carries information from the DNA in the nucleus to the appropriate site where proteins are synthesized. Why is it necessary to have an intermediate in the form of RNA?

• A)Proteins cannot be synthesized properly from DNA because the process calls for an additional step in the form of an RNA molecule because of the chemistry of synthesis.
• B)DNA is a large enough molecule that it can not leave the nucleus to move through the cytoplasm of the cell.
• C)The code carried in the DNA molecule is too large and must be broken down in to manageable pieces. RNA carries those pieces which are severed from the parent DNA molecule.
• D)The genetic code for proteins is inherited from one's parents in the form of the RNA molecule which moves throughout the cytoplasm.
