Study Notes
Methods for Analyzing Genome Transcription
- In the past, hybridization-based approaches were mostly used to answer questions about which parts of the genome are transcribed.
Next-Generation Sequencing (NGS) Advantages
- NGS-based approaches have an advantage over hybridization-based approaches, offering a more comprehensive and unbiased view of the transcriptome.
Hybridization-Based Approach Limitations
- The genes or parts of the genome that are analyzed in a hybridization-based approach are determined by the probes or microarrays used.
RNA-Seq Data Analysis
- RNA-Seq data analysis is primarily based on the mapping of sequencing reads to a reference genome.
RNA-Seq Data Interpretation
- The total number of reads mapped to a particular genomic region in RNA-Seq data analysis represents the expression level of the corresponding gene or region.
