5 True/False questions
What is the difference between transcription and DNA replication? → In the nucleus
Who were Watson and Crick? → Science lab on Long Island; used radioactively labeled viruses made of only protein and DNA; the viruses infected the bacteria and only transferred the DNA; concluded that genetic material in the viruses was DNA
Define Nucleotides? → building units composed of DNA. Consists of the four base groups, a deoxyribose sugar and a phosphate group
What is Insertion? → When an extra base is inserted
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)
