Chapter 14, Problem 5FTB
Summary Introduction
To review:
The given blank space in the statement, “pieces of deoxyribonucleic acid (DNA) can be separated according to size by a process known as __________________. The identity of a specific sample of DNA is usually determined by binding a synthetic piece of DNA called a(n) __________________, which binds to the sample DNA by __________________.”
Introduction:
For the proper detection of particular genes in the DNA strands, it is necessary for the separation of the DNA strands from each other. The separation is usually done on the basis of their size. The technique by which the DNA strands are separated is called gel electrophoresis.

In general, which part of a DNA sequence will have the best quality? (Ex. Beginning, middle, end?) Why?
During the process of Gel Electrophoresis, DNA will move through the gel towards the-------end of the gel, based on DNA having an overall------charge and the-----DNA fragments will travel the furthest.
Choose from the following answers: negative, positive, smallest, largest, medium
After a piece of DNA is sequenced, what type of analyses can be performed?
