Method for transcription of a DNA sequence

摘要

A DNA sequence transcribing method involves labeling a DNA fragment with a fluorescent substance, subjecting the labeled fragments to electrophoresis, exposing a gel containing the DNA fragment to light during electrophoresis, and detecting fluorescence generated upon exposure. An image corresponding to a fluorescent image on the gel is transcribed on a recording medium by entering a detecting signal in synchronization with operation of detecting fluorescence on the gel containing the DNA fragment after electrophoresis. This arrangement enables a crude fluorescent image on the gel containing the DNA fragment to be recorded as an intact image of the DNA sequencing on the basis of the fluorescent method, and the image can be retained.
