Summary
Profiles the genome or transcriptome of individual cells, revealing hidden heterogeneity.
In depth
Droplet microfluidics (10x Genomics) captures thousands of cells; barcodes track cell origin. It identifies cell types and trajectories and reveals rare populations. Human Cell Atlas aims to map all cell types.
Cell-specific barcodes and unique molecular identifiers allow counting. Clustering and dimension reduction (UMAP) visualise cell types. Lineage tracing follows developmental paths.
Remember: dropout (missing detection) is common due to low RNA amounts per cell.
Frequently asked questions
What is Single-Cell Sequencing?
Profiles the genome or transcriptome of individual cells, revealing hidden heterogeneity.
Which area of biology covers Single-Cell Sequencing, and how advanced is it?
Single-Cell Sequencing is one of the 56 topics in Biotechnology & Genomics. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Comparative Genomics, RNA-Seq, Genomics.
Can you give an example of Single-Cell Sequencing?
It uncovered new immune cell subsets.
What should I learn before Single-Cell Sequencing?
Work through the Beginner topics in Biotechnology & Genomics first, such as Biotechnology, Genetic Engineering, Selective Breeding, then return to Single-Cell Sequencing. Advanced topics assume the Intermediate vocabulary.
What topics are related to Single-Cell Sequencing?
The closest topics to Single-Cell Sequencing are Comparative Genomics, RNA-Seq, Genomics, Proteomics. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Single-Cell Sequencing?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Single-Cell Sequencing. To practise the whole of Biotechnology & Genomics, use the Biotechnology & Genomics quiz.
How is Single-Cell Sequencing different from Comparative Genomics?
Single-Cell Sequencing: Profiles the genome or transcriptome of individual cells, revealing hidden heterogeneity. Comparative Genomics: Comparing genomes of different species to identify conserved functions and evolutionary changes. Read both side by side and note what each one explains.
How should I study Single-Cell Sequencing step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Comparative Genomics and explain the difference aloud. Finally, take the Biotechnology & Genomics quiz and come back to this page for any question you miss.
