OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.

OneClass has allowed me to catch up with my most difficult course! #lifesaver

Description
LECTURES 14 1. What information could you obtain from a genetic approach of studying mutants defective in a particular process? the potential function and importance of the protein identificationisolationsurvival of mutants how many genes are involved in a certain process order of these genes (proteins) in the process by applying genetic approach (complementation analysis) interaction between different genes (proteins) by using genetic approach (genetic suppression) 2. How would you define permissive conditions in respect to temperature sensitive mutants? permissive conditions are the temperatures at which the mutants can survive and grow 3. Define (or compare and contrast): a) gene expression; transcription; replication; translation; b) gene; allele a) Gene Expression: the processes through which the information carried by a gene is converted into an observable product (either RNA or protein) Transcription: the process of copying DNA to RNA by enzymatic processes Replication: the process of copying a double stranded DNA molecule (DNA synthesis) Translation: the process that converts an mRNA sequence into a chain of amino acids that form a protein b) Gene: the functional unit of heredity; the entire DNA sequence necessary for the synthesis of a RNA molecule or functional polypeptide (it includes coding and regulatory regions) Allele: different version of the same gene 4. Explain by using your own words the meaningsignificance of gene expression. gene expression is the conversion of a sequence of DNA into a final observable product (either RNA or protein) it is important since all living things rely on proteins to function and survive everything inabout the living cellorganism is about proteins 5. What are the roles of model organisms in molecular biology studies? Choose two model organisms and explain your reasoning. model organisms help us understand (at a basic molecular level) how something affectsalters cells and the organism in general; can be extrapolated to more complex organisms Escherichia coli Drosophila short reproductive period useful for genetic experiments simple developmental studies body plan formation relatively cheap relatively small easy to maintain cheap lots of data available easy to maintain 4 million bp lots of data available 4000 different proteins first to be extrapolated to higher mammals divides every 2060 minutes simple nutritional requirement 6. What are three main functions of DNA? Explain the importance of each of them. stores information sequence of bases codes for proteins, RNAs, regulatory signal replicates faithfully semiconservative replication is basis of reproduction and cell growth ability to mutate basis of evolution and allelic variation 7. What is (are) the role(s) of phosphodiester bonds in DNA structure? What is (are) the role(s) of hydrogen bonds in DNA structure? What is (are) the role(s) of hydrophobic interactions in DNA structure? phosphodiester bonds contain a negative charge thus, the backbone contains a negative charge that repels two different strands from each other; rigid covalent bonds that are basis of structure hydrogen bonds keep the two strands held together complementary base pairing the hydrophobic interaction helps stabilize the molecule since it forces the nitrogenous bases together and keeps the two negatively charged backbones apart
