5 True/False questions

  1. What is translation?The process of converting information in a sequence of nitrogenous bases in mRNA into a sequence of amino acids in proteins


  2. RNA transcription is similar to what process in DNA?DNA replication


  3. Chart out RNA (nucleic acid)RNA - single chain structure - contains ribose sugar - bases are adenine, cytosine, guanine and uracil - RNA is found in the nucleus and cytoplasm - there are three different types of RNA - messenger RNA (mRNA); ribosomal RNA (rRNA); and transfer RNA (tRNA)


  4. What are the three stop codons?1) Messanger RNA - mRNA
    2) Transfer RNA - tRNA
    3) Ribosomal RNA - rRNA


  5. How does transfer RNA help in translation?By bringing 20 different amino acids dissolved in the cytoplasm to the ribosomes
