Protein Synthesis: Transcription and Translation
CP Biology
Why are proteins important to the cell?
• Proteins are building blocks – they make up your body structures, determine your traits– they are YOU!
• Proteins are made according to the information in your DNA…your genes.
What is RNA?
• RNA = ribonucleic acid• Single-strand of nucleotides• Different sugar – ribose• Contains Uracil (U) instead of Thymine (T)
Why is RNA needed?
• It is small enough to fit through the nuclear pores to travel outside the cell.
• Where does it go?• Messenger RNA – called mRNA takes the
message from DNA to the ribosome
