- The enzymes BamH I and Bal II recognise different sequences but leave the same stickyends: BamH I: ----------G|G A T C C ------ Bal II: ----------A|G A T C T ------(i)Will the two enzymes result in the same number of fragments in a random DNAsequence? Give reasons.(ii)What’s the advantage of having such a pair of REs? Explain with example.Why do you suppose that forensic DNA analysis relies principally onshort tandem repeats (repeat polymorphisms) rather than single-nucleotidepolymorphisms?The epsilon subunit of DNA polymerase III is responsible for its _______ activity.A-5'---->3' polymerase B- Sliding clampC-3'----->5' exonuclease activity D-5'------>3' exonuclease activity
- COMPLEMENTARY DNA SEQUENCE OF GACGGCTTAAGATGCWhy is DNA supercoiling called supercoiling rather than just coiling? Why is positive supercoiling called overwinding and negativesupercoiling called underwinding? How would you define theterms positive and negative supercoiling for Z DNA?The text stated that molecular biologists have developed elegant techniques that can convert any type ofDNA end into any other type of DNA end. In thisproblem, consider genomic DNA that is broken bymechanical shearing into random pieces. Some of theends of these pieces are blunt, some have 5′-overhangs, and others have 3′-overhangs.a. Must the two ends of any one genomic DNAfragment be of the same type?b. Explain why the ends with 5′ or 3′ overhangs arenot sticky.c. Researchers can convert ends with overhangs intoblunt ends using either DNA polymerase (plus thefour dNTPs), or nuclease S1, which degradessingle-stranded regions of DNA but not doublestranded regions. Which kinds of ends with overhangs (5′ or 3′) could be converted into blunt endsusing DNA polymerase? With S1 nuclease?
- In addition to correcting DNA mismatches, themismatch repair system functions to prevent homologousrecombination from taking place between similar but notidentical sequences. Why would recombination betweensimilar, but nonidentical sequences pose a problem forhuman cells?If the bandicoot genome is 3.62 x 109 base pairs, and the "highly repetitive DNA" fraction is composed entirely of copies of sequence 5'TGCGTGTGTGC3' and its complement, how many copies of this sequence are present in the bandicoot genome?Even in automated sequencing, where you can include all 4 ddNTPs in one reaction, you need to include "normal" dNTPs as well as the ddNTPs - why are these necessary? Why can't you just put in the ddNTPs, since you've got all four of them available to the DNA polymerase?
- A duplex DNA molecule contains a random sequence of the four nucleotides with equal proportions of each. What is the average spacing between consecutive occurrences of the sequence 5'-ATGC-3'? Between consecutive occurrences of the sequence 5'-TACGGC-3'?2b) If you denatured the random 1000 bp fragments of potoroo DNA by heating them to 95°C. and then cooled them down to 60°C and allowed them to reanneal, you would find that approximately 20% of the DNA fragments renatured very rapidly, another 30% of the DNAfragments renatured moderately rapidly, and the remaining DNA fragments renatured relatively slowly. From these results, whatfraction of the potoroo genome is composed of highly repetitiveDNA? helpful InformationWhen a segment of DNA containing either aVNTR or an RFLP is analyzed, the result is fragments of DNA ofdifferent lengths. How, then, are VNTRs and RFLPs different?
