Chapt Key Topic Questions
  DNA a)   What is found in Nucleic Acid
    b)   Why are ratios of base pairs linked to type of base?
    c)    What portion of DNA define genes?
    d)   Where does replication occur
    e)   What are the steps and proteins involved in replication?
    f)     What is the backbone of DNA made of?
    g)   How can you use a diagram of DNA replication to identify specific base pairs
    h)   What are three properties of DNA? (SAS)
    i)     What are the specific steps for both replication.
     
  Protein Synthesis ·      Where does RNA get made in a cell?

·      What is involved in:

·      Transcription

·      Translation

    What is the function of

·      mRNA

·      tRNA

·      rRNA

    What are the structure and function of a

a)DNA

b) Codone

c) Anticodon

d)triplet

    How do you use mRNA and tRNA tables to define what proteins should be created from a strand of DNA?
    What is the role of restrictive enzymes in protein synthesis?
  Mutations What is a definition for “mutation”

How would the code for a protein change for point mutations?

  Bio tech How does recombinant DNA work?
    How can helicase and polymerase be used in biotechnology?
     
  Enzymes ·      What is the role of enzymes in reactions
    ·      What is activation energy
    ·      How can you increase or decrease an enzyme reaction?
    ·      What is the role of a coenzyme?
    ·      What two theories are linked to enzymes?
    ·      What are three factors that can create a significant change in an enzyme?
    ·      There are four types of bonds in enzymes, which 3 factors factors affect these four types of bonds and how?
    ·      What is competitive inhibition
    ·      How can a coenzyme help an enzyme work? (example?)
    ·      How can an end product of a metabolic pathway be used to control its own production?
    ·      In our class experiment we used the enzyme “amylase” to break down corn starch, what would happen if we used pepsin instead?
    ·      What are four factors that could slow or speed up an enzymatic reaction. (note this is not to denature the enzyme)
    ·      How did we use a data table to decide which enzyme has been denatured?
