DNA 3 - Structure & How it Codes

    Cards (11)

    • DNA consists of two strands wrapped around each other in a double helix. 
    • DNA is considered to be a polymer because it is made up of multiple monomers. 
      What are the monomers of DNA called? 
      Nucleotides
    • C
    • There are four types of bases in DNA. What are their names? 
      A - T - C - G
      Adenine
      Thymine
      Cytosine 
      Guanine 
    • What is the part labelled A?



      Phosphate
    • What is the part labelled B?
      SUGAR
    • gene is section of DNA, with a particular sequence of bases, that codes for a protein. 
    • amino acid
    • DNA and proteins 
      • The sequence of bases in DNA determines the sequence of amino acids in the chain.
      • The chain of amino acids (a 'polypeptide'), then folds up to formprotein.
      • Different sequences of amino acids lead to proteins with different shapes.
      • This allows different proteins to carry out different functions.
    • One function of proteins is as to act as enzymes.
      What is the role of enzymes? 
      To speed up the rate of chemical reactions 
    • One of the uses of proteins is to carry messages around the body. 
      What do we call these proteins? 
      Hormones
