Later, in 1960, the discovery that an RNA molecule and a DNA molecule could form a hybrid ... categories of RNA play a critical role in the translation process: tRNA and rRNA.

This process involves two main steps: transcription and translation. During transcription, the DNA sequence of a gene is copied into a complementary RNA molecule called messenger RNA (mRNA). This ...

(a) The basic elements of FISH are a DNA probe and a target sequence. (b) Before hybridization, the DNA probe is labeled by various means, such as nick translation, random primed labeling ...
