Biology Questions

The process of copying genetic information from one strand of the DNA into RNA is termed as transcription. In transcription, only a segment of DNA and only one of the strands is copied into RNA. This necessitates defining the boundaries that would demarcate the region and the strand of DNA that would be transcribed.

Control processes depend on the prefrontal cortex which shrinks with age. Inadequate control processes may explain why many older adults have extensive vocabs (measured by written tests) but limited fluency (when they write or talk).
