2 Lecture 1 Introduction to terms, techniques and concepts in molecular biology
3 Molecular biology - a primer
4 Human body has 100 trillion cells each containing 3 billion pairs of nucleotides. xxxxxxxxxxxxx A 6 foot human has so much of DNA that it can travel to and fro, from Earth to Sun 600 times!!!
5 RNA polymerase (yellow) attaches to a DNA, walks down the DNA and creates a copy of DNA into a strand of messenger RNA (blue) The mrna strand floats free and finds a ribosome (green). Ribosome churns out a chain of amino acids (purple) Amino-acid chain folds into the protein
6 Glossary Genome The entire genetic component of an organism ORF (open reading frame) A series of codons starting with an initiation codon and ending with a termination codon DNA sequencing The technique for determining the order of nucleotides in a DNA molecule DNA replication Synthesis of a new copy of DNA molecule DNA polymerase An enzyme that synthesizes DNA Cloning Inserting DNA fragment into cloning vector and propagating recombinant vector in a host organism
7 Question time An ORF represents an open reading frame. Is there a CRF too? (CRF = closed reading frame)
8 Vectors Vector Insert size p=95% (human genome) Lambda vector 18 kb Cosmid, fosmid 40 kb PI 125 kb BAC, PAC 300 kb YAC 600 kb Mega-YAC 1400 kb The size of the library depends on the cloning vector
9 Restriction Enzymes DNA cutting enzymes found in bacteria. Example: Hae III 5 G G C C 3 3 C C G G 5 Blunt ends EcoRI 5 G A A T T C 3 3 C T T A A G 5 Sticky ends DNA ligase joins the broken ends
10 Eco RI in action
11 Restriction map of pbr322
12 Question time A student repeatedly failed to cut a plasmid with two different restriction endonucleases, even though he was using the enzymes in good condition and the plasmid had sites for both.
13 Plasmids 1. Extrachromosomal circular DNA molecules which are not part of the bacterial chromosome. 2. Size range: kb 3. Carry functions advantageous to hosts e.g., (a) produce enzymes which degrade antibiotics or heavy metals (b) produce restriction and modifying enzymes. 4. Replication is coupled to host replication in both stringent (1-2 copies / division) and relaxed manners ( copies / division).
14 How do you insert foreign DNA into plasmid? Cut plasmid on a unique restriction site Also cut the insert by the same restriction enzyme (preferably) Incubate linearized plasmid with the fragment to be inserted Check insertion by gel electrophoresis
15 Finding a way into plasmid s territory
16 Question time Devise a strategy to ligate an insert with the linearized plasmid given that the insert has a blunt end and plasmid has a sticky end?
17 Transformation Insertion of recombinant plasmid into bacteria 1. Chemical: e.g., calcium phosphate mediated 2. Physical : e.g., electroporation, DNA gun 3. Viral: e.g., retroviruses
18 Bacteria - a living photocopy machine
19 Producing insulin through genetic engineering
20 Effect of plasmid size on transformation efficiency Molecule size (kb) % Maximum probability
21 Question time Given the task of sequencing a large stretch of DNA, what plasmid size would you choose for transformation into bacteria and why?
22 Artificial vehicle acting naturally
23 What is cloning? A procedure to generate large number of copies of a single sequence of DNA Properties 1. The host will accept foreign DNA and can still complete its life cycle 2. Permit the host to divide normally and be distinguished from non transformed members of community
24 cdna cloning It is a method of obtaining a DNA copy of the mrna and making a library out of it. STEPS 1. Bind oligo DT to the poly A tail of the mrna 2. Add reverse transcriptase and make its cdna copy 3. Digest mrna and add poly C tail to 3 end of DNA 4. Add oligo dg and synthesize a complementary strand 5. Add dc s to the 3 end of double stranded cdna 6. Insert dc tailed DNA to dg tailed linearized plasmid 7. Transform E.coli cells 8. Use selection makers to identify transformed cells
25 Question time Is there a way to prevent self-ligation of linearized plasmid? If No explain why, if Yes explain how.
26 Creating genomics DNA library
27 What is a genomic library? A genomic library contains DNA fragments which when aligned together represent the entire genome. The major problem Not all the fragments find their way into plasmids!!!
28 Question time What strategy would you use to include the entire genome into plasmid library
29 Chromosome walking It is a technique for constructing a clone contig by identifying overlapping fragments of cloned DNA Contig: is a continuous set of overlapping DNA sequences
30 Question time What is the best way to walk through a highly repetitive DNA?
31 PCR: Polymerase Chain Reaction Also known as Molecular photocopying Invented by Kary Mullis - mid 1980s The real story behind PCR. Taq polymerase: Thermus aquaticus 3 steps: Denature, Anneal & Elongate
32 PCR protocol - an overview
33 Theory and Application of PCR
34 PCR Animation follows * o C for sec (denature) * o C for sec (anneal) * 72 o C for sec (elongate) (60 sec per kb target sequence length) * cycles only (otherwise enzyme decay causes artifacts) * 72 o C for 5 min at end (to allow complete elongation of all product DNA)
