What are the fragments making up the noncontinuous strand called?

The fragments making up the noncontinuous strand in DNA replication are called Okazaki fragments. These are short DNA fragments that are synthesized discontinuously on the lagging strand during DNA replication.


How can one determine the size of DNA fragments from electrophoresis?

One can determine the size of DNA fragments from electrophoresis by comparing the distance the fragments have traveled in the gel to a standard marker with known fragment sizes. The smaller fragments will travel farther while larger fragments will travel a shorter distance. This allows for estimation of the size of the DNA fragments based on their migration pattern.


Explain how an agarose gel can separate DNA fragments of different lengths.?

The separation of DNA fragments is based on size. When a DNA sample is run in a gel (electrophoresis), the lighter fragments migrate faster than the heavier (longer) fragments under the influence of an electric current. At the and of the process, the shorter fragments are found at the terminal end of the gel and the longer fragments closer to the origin


Gel electrophoresis separates DNA fragments on the basis of differences in their?

Length. DNA has a natural negative charge - and so will move towards the positive electrode. Larger fragments move more slowly than shorter ones - so the sizes of fragments can be determined.


What is the function of a DNA ladder in gel electrophoresis and how does it aid in the analysis of DNA fragments?

In gel electrophoresis, a DNA ladder serves as a reference for determining the sizes of DNA fragments being analyzed. It contains DNA fragments of known sizes, which help in estimating the sizes of unknown DNA fragments by comparison. This aids in accurately identifying and analyzing the DNA fragments present in the sample.
