How to Read Autoradiogram?

The sequence in the 5'-to-3' direction is read from the bottom to the top of the autoradiogram. strand can be read directly from the autoradiogram. One starts at the bottom and looks across the four lanes to find the lane containing the band corresponding to the shortest fragments.

How do you read a sequencing gel?

To read the gel, you look at the dark bands in each column. There is one column for each type of nucleotide (G, C, A, T). By reading the sequence of the bands, you can determine the sequence of nucleotides. Left: X-ray that shows the columns and bands for the four nucleotides.

How do you read a DNA sequence ladder?

The DNA sequence is read from bottom to top, according to the known order of the four termination reactions at top. The sequences of both DNA strands are typically determined and compared as a check on accuracy.
