RNA-Seq

Among different methods to evaluate gene expression, the high-throughput sequencing of RNA, or RNA-seq. is particularly attractive, as it can be performed and analyzed without relying on prior available genomic information. During RNA-seq, RNA isolated from samples of interest is used to generate a DNA library, which is then amplified and sequenced. Ultimately, RNA-seq can determine which genes are expressed, the levels of their expression, and the presence of any previously unknown transcripts.

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated. This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
FAQs
The RNN receives CNN-derived features in temporal order and updates its hidden state as each new frame or sensor input arrives. That hidden state carries information from earlier observations into later processing, allowing the model to relate separate movements or measured events within one sequence. This temporal linkage helps distinguish complex behaviors that cannot be interpreted from a single observation alone.
The CNN and RNN address different aspects of the input. The CNN identifies patterns within an individual video frame or structured sensor input, whereas the RNN analyzes how those extracted patterns change over time. Separating these roles lets the architecture combine momentary spatial or measured information with temporal context, supporting recognition of actions, gestures, and activity sequences.
The order of feature inputs matters because the RNN uses successive observations to update its hidden state. A sequence preserves how behavior unfolds, while isolated or rearranged observations provide less temporal context. Consequently, the same visual or sensor patterns may support different interpretations when their progression through time changes, which is important for distinguishing activity sequences and other complex behaviors.
A typical workflow begins with video frames or structured sensor inputs. The CNN processes each input to produce features, and those features are then supplied sequentially to the RNN. The combined architecture uses the resulting spatial and temporal information to recognize or classify a human or animal action, gesture, or activity sequence, producing an automated behavioral analysis.
The architecture can work with video frames as well as structured sensor inputs. Video provides frame-level information from which visual patterns can be extracted, while sensor data supplies measured patterns in an organized form. These inputs can support analysis of human or animal actions, gestures, and activity sequences, allowing the same general framework to connect observations across time.
In behavior research, the model can support recognition and classification of actions, gestures, and activity sequences. Its output helps convert frame-level or measured observations into an interpretation of behavior unfolding over time. This automated analysis can assist researchers in characterizing complex behavioral patterns and in examining temporal relationships that would be difficult to represent using individual inputs alone.
