  4. What is a gene? Define the term gene. Genes code for polypeptides. Give examples of the polypeptides they may code for:

  5. Protein synthesis – TRANSCRIPTIONDescribe the stages of transcription

  6. Protein synthesis – TRANSLATIONDescribe the stages of translation.

  7. Describe the roles of the following in protein synthesis.

  8. How DNA codes for proteins • Complete the table below.

  9. MUTATIONS Define the following terms: • Insertion • Deletion • Point mutation • Frameshift • Missense mutation • Nonsense mutation • Silent mutation

  10. Effects of mutationsDescribe one example of a mutation having a…

  11. Lac operonMatch the components of the lac operon system and regulator gene with the correct functions.

  12. Lac operonDescribe how the lac operon works in the following situations: What is the advantage of E.coli possessing this lac operon?

  13. Controlling the body planUse the words below to fill in the gaps in the sentences HOMEOBOX BODY PLAN TRANSCRIPTION HOMEOTIC PROTEINS MORE SEGMENTATION HOX • The general structure of an organism is called its ______ _______. • During the embryonic stage, the polarity of an organism is determined by differing concentrations of __________. Differing mixes of proteins also controls the ______________ of the embryo in which the main body sections are established. • The overall body plan of any organism is determined by a sequence of 180 base pairs called the ________________ genes. • These genes code for the production of proteins called __________________ factors. These proteins can bind to a particular region of DNA and cause it to be transcribed or not transcribed. This in effect is turning other genes on or off. • ___________ genes control the specialisation of the segments. Each segment develops into specific structures in the adult. • The homeobox genes are arranged in clusters known as ______ clusters. More complex organisms tend to possess __________ of these clusters.

  14. Cell deathCompare and contrast apoptosis and necrosis

  15. ApoptosisDescribe the sequence of events that leads to apoptosis (programmed cell death)
