DNA makes copies of itself when the enzyme DNA helicase unzips a strand. Nucleotides with base pairs corresponding to the original strand are connected together with the help of DNA polymerase. The new strands of DNA connect with the old strands using hydrogen bonds, yielding two sets of DNA.
tRNA translate the codons on mRNA once they travel from the nucleus to the ribosome. The information from the mRNA is used to form proteins.
mRNA containing information for protein synthesis, provided by the genes in DNA, is formed when DNA is unzipped and used to form a nucleotide strand.

Process by which proteins, used for coding for traits, are synthesized using transcription and translation.
RNA is a nucleic acid like DNA, but it is single-stranded. Unlike DNA, it has ribose, and it uses the base Uracil in the place of Thymine. It is small enough to pass outside the nucleus.
