Question
Chapter 13, 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.

Students have asked these similar questions
In general, which part of a DNA sequence will have the best quality? (Ex. Beginning, middle, end?) Why?
The concentration of digested and cleaned DNA is found to be 5μg/mL. How much of your DNA sample (in μL) would require to obtain a final concentration of 30ng.
Guanine, cytosine, thymine, and __________________ are the four __________________ in DNA.
In DNA, guanine always forms hydrogen bonds with __________________.
The process of __________________ produces a new copy of an organism’s genetic information, which is passed on to a new cell.
The double coiled, “staircase” shape of DNA is called a __________________.

- DNA has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. One aspect of DNA that allows it to accurately store genetic information is the base pairing from Chargaff's first rule of the four nucleotide bases.
