DNA fragments with the same number of nucleotides will move through the gel at different speeds ? True or False?
Homework Answers
Answer: False.
Explanation: The DNA being negative charged, will move towards the positive pole in electrophoresis. The basis for the separation is done on the size of the DNA fragments. Shorter fragments will move quickly while as longer fragments will move slowly. The DNA fragments having same number of nucleotides is having same length so they will be moving with the same speed.

D ONA that has many restriction sites for a certain endonuclease will be cut into more fragmets than DNA with fewer restriction sites. 4. Cutting DNA with many different endonucleases will result in more DNA fragments. 5. Restriction enzymes all recognize the same base sequence when...

NA fingerprinting uses a process called gel electrophoresis to separate the fragments of DNA. Once the DNA fragments are sorted, the pattern of bands can be analyzed. 1)Gel Electrophoresis Procedure The smaller DNA fragments start to move away from the wells and the larger DNA fragments remain closer to the wells. 2)An electric current is passed through the gel. 3) DNA fragments are treated with a dye. 4)A restriction endonuclease is added to the DNA. 5)Using micropipettes, the DNA samples...

1a) A band on an electrophoresis gel corresponds to _____ Choices: - the size standard - millions of fragments of the same size - a DNA fragment of a particular size - the blue tracking dye b) What is the function of the size standard? Choices: - it allows the researcher to calculate the unknown sizes of the DNA fragments by comparing then to then known sizes. - it marks the location where the fragments should line up. c) Longer...
