(topic 1 and 4 in blank deal-out. )

3 Child's DNA 3

4 A.F. #1 DNA 4

5 A.F. #2 DNA 5




Record the separation each ladder fastening moved from the polite in mm concurrently following a while the largeness of the DNA dross in that fastening in bp units, naturalized on the bp attached in stride 19 , in your Lab Notes.


Lane 1:


1,000 bp 34 mm

900 bp 36 mm

800 bp 38 mm

700 bp 40 mm

600 bp 43 mm

500 bp 47 mm

400 bp 51 mm

300 bp 56 mm

250 bp 60 mm

200 bp 64 mm

150 bp 69 mm

37 mm 850bp

44 mm 575bp


Lane 4:


41 mm 670bp

43 mm 600bp


Lane 5:


44 mm 575bp


55 mm 320bp


Experiment: Agarose Gel Electrophoresis of DNA Fragments

Lab Results

  1. List the separations expeditioned in mm for the fastenings in the DNA ladder in the consultation underneath.
    Remember, feebleer dross expedition farther than longer ones, so the top-most fastening gain be the 1,000 bp largenessd DNA dross forasmuch-as the bottom-most fastening gain be the 50 bp largenessd DNA dross.

  2. Whose scantling had the closely 570 bp and 320 bp largenessd DNA dross?
  3. What were the largenesss of the DNA dross for alleged senior #1?

Data Analysis

  1. Which largeness DNA morsel did the child enjoy from her woman?
  2. Which alleged senior, if any, can be definitively firm out as the child's biological senior?


  1. How are new molecules of DNA synthesized in livelihood cells?
  2. What is the exercise of DNA?


    DNA has genetic notice that restrains our cells. So, DNA is relish a blueprint that shows how to erect components of cells relish proteins and ribonucleic thin (RNA). This notice is carried down to newer generations through enjoyance.

  3. If each single has such a feeble total of DNA in their cells, how do the fastenings on the gel inclose plenty DNA to be manifest?
      In direct to compel DNA manifest. The Gel has to be soaked in a dye (ethidium bromide) to fasten following a while the DNA and rinsed off following. Ethidium bromide helps to compel DNA manifest by fervid brightly in UV rays.
  4. Humans barely accept a few eye colors and barely disgusting ABO-naturalized order marks. How can DNA tests definitively confirm singles when sundry fellow-creatures accept brown eyes or mark A order?
  5. Suppose a likely hair was root in a victim’s residence. A gel is set up following a while the DNA dross of two reported criminals in lanes 4 and 5, the DNA dross of the likely hair in lane 3, and the victim’s DNA dross, as a denying restrain, are in lane 2. A DNA ladder is in lane 1. The resulting gel is underneath. Which conjecture, if any, committed the offense? Explain your counterpart.
