Name ___________________________________________ period _______ Date _________________ DNA Do Now self Notes 1) DNA stands for _____ eoxyribo _____ ucleic _____cid 2) DNA is made of units called ____________________ 3) What are the 3 parts of a nucleotide? A) ________________________ B)______________________ C) ______________________ 4) Draw arrows To diagram 5) Name the 4 nitrogen bases? A = ________________ T =________________ G =________________ C =________________ 6) Match these bases to their base pair A- ________ T - _______ G - ______ C - _______ 7) The chains of ________________ form a sequence which is the genetic code 8) DNA structure - DNA forms a spiral or twisted ladder shape called a ____________________ 9) Rungs (steps) are made of base pairs connected By weak ________________ bonds 10) Sides of the ladder are made of phosphates and sugars (deoxyribose) With strong ________________ bonds 11) Who discovered the Double Helix ? ____________ and ___________ 12) DNA replication is when DNA duplicates itself before mitosis in the ____________ phase of cell cycle 13) DNA replication enzymes - The 2 main enzymes are: Helicase – ___________ apart the DNA strands Polymerase – Attaches new nucleotides to _____________ new strands 14) DNA Checkpoints - DNA must be replicated perfectly so the new cells that form are identical. The Cell cycle use proofreader enzymes to ensure there are no ____________ in the DNA Mutation – when an ____________ sequence gets copied and passes the checkpoint 15) Complete the replication of the following side of a DNA strand below: A T C A C G G A T G T C 16) Proteins are produced from DNA using 3 nucleotide code letters at a time for each amino acid. What would happen to the proteins produced if the first T was deleted (mutation) and all the nucleotide code letters shifted to the left?
