BSC 2010 Studv questions 3nd exam these questions generally emphasize knowledge of processes and mechanisms You will need to know additional facts from your notes such as de nitions of terms 1 What was the rationale for the Hershey Chase experiment and what did it show 2 What is the structure of RNA and DNA nucleotides Which bases are purines and which are pyrimidines What39s the difference between purines and pyrimidines How are nucleotides linked together in strands of DNA and RNA Why are added nucleotides initially triphosphated 3 What bases are paired in double stranded DNA What holds them together What does 3 and 539 mean and what is the 3 5 orientation of DNA strands 4 From your HANDOUT What are origins of replication replication bubbles and replication forks What are the functions of helicase single strand binding proteins primase RNA primer DNA polymerase and DNA ligase in DNA replication What is different about the synthesis of the leading strand and the lagging strand Can you predict the sequence of bases and 3 5 orientation in a newly synthesized DNA strand given the sequence and 35 orientation of bases in the parent strand it is paired with 5 What is a mutation What are different types of mutagens 6 What happens in the initiation elongation and termination steps in transcription What are the specific roles of the promoter transcription factors RNA polymerase terminator sequence Can you predict the sequence of bases and 3 5 orientation in a mRNA strand given the sequence of bases and 3 5 orientation in the DNA strand containing the gene 7 What are the steps by which eukaryotic cells convert premRNA to mRNA What are exons and introns 8 How does tRNA bring about alignment of specific amino acids with specific codons in translation What is the relationship between codons and anticodons Can you predict the anticodon given the codon and vice versa 9 What types of molecules are found in ribosomes and what are the ribosomal subunits 10 How are the 64 codons used Can a codon code for more than one amino acid Can there be more than one codon for a particular amino acid What happens in base substitution and base additiondeletion frame shift mutations 11 What are the different types of viral Nucleic acids DNA RNA Single strands Double strands and examples of diseases they cause 12 What is the difference between lytic and lysogenic viral infections How does a retrovirus work 13 How is DNA arranged in bacteria What are the different mechanisms for rearranging genes DNA in bacteria 14 How is transcription of genes for lactose digestion regulated by the Lac operon 15How is DNA arranged in Eukaryotic cells What are the levels of control of gene expression in eukaryotes What are examples of posttranslational additions to proteins 16 What is the difference between tissue organ and organ system Can you give examples of each 17 Where in the digestive system does digestion of particular types of molecules occur in humans What types of enzymes are involved and what are the uids that contain them What is the function of acid in the stomach and bile from the gall bladder 18 Where does absorption of nutrients and water occur What is the role of villi and microvilli What does the liver do to absorbed nutrients 19 How does peristalsis causes food to move through the digestive system 20 What nutrients are essential in the diet What is the need for particular vitamins and minerals Hormones affecting processes we have studied Hormone name Antidiuretic Hormone Thyroid Hormone Aldosterone Cortisol Epinephrine Insulin Glucagon Where Secreted Pituitary gland Thyroid gland Adrenal gland cortex Adrenal gland cortex Adrenal gland medulla Pancreas Pancreas More hormones will be covered in Biology 2 Effect Increases water reabsorption in Kidney concentrates urine saves body water Stimulates aerobic respiration for Body heat Increases Na reabsorption in Kidney Raises blood glucose helps body cope with stress Raises blood glucose Increases heartbeat Increases blood pressure prepares body for emergency action Lowers too high blood glucose Raises too low blood glucose
