Researchers identify two distinct gene transcripts of a single gene that could regulate color patterns in Saintpaulia flowers The researchers hypothesized that the white-striped petal pattern was due ...

Scientists have developed some incredibly advanced ways to actually visualize gene activity in tissues. A sample of tissue ...

Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding snippets of RNA are bracketed by a guanine-thymine (GT) nucleotide sequence ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...
