DEFINITION

Classification: 435/91.21

Involving the making of multiple RNA copies:

(under subclass 91.2) Processes which result in a geometric or exponential, rather than an arithmetic increase in the number of copies of a ribonucleotide sequence or sequences.

(1) Note. Transcription amplification is included in this subclass.
