This molecule carries genetic information from the nucleus to the ribosomes in the cytoplasm.

• rRNA
• tRNA
• mRNA
• DNA

What is the purpose of this process?

• To translate the genetic code into a specific sequence of amino acids

• To synthesize amino acids used to unzip strands of DNA and copy the genetic code

• To assemble nucleotides in an mRNA chain along a DNA template

• To replicate the DNA of an organism before cell division
