Questions about the DNA Sequencing poster

What’s on the DNA Sequencing poster?

Sanger sequencing against Next-generation, side by side. Sanger sequencing: Chain-terminating dideoxynucleotides; Sanger sequencing: Read length ~800–1,000 bases; Sanger sequencing: Very high accuracy; Sanger sequencing: One fragment at a time; Sanger sequencing: Still the standard for single genes; Next-generation: Millions of fragments in parallel; Next-generation: Short reads, 100–300 bases typically; Next-generation: Assembled computationally; Next-generation: Whole genomes in hours; Next-generation: Cost per genome has fallen enormously; Long-read technologies — nanopore, PacBio — read tens of kilobases, resolving repeats…. The Human Genome Project took 13 years and about $3bn. A genome now costs a few hundred and takes about a day.

Who is the DNA Sequencing poster for?

DNA Sequencing belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning genetics can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the DNA Sequencing poster?

Sanger reads long and accurate. Next-generation reads short and massively parallel. A wall chart earns its place by being glanceable from where the work is happening, so DNA Sequencing belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.

What other posters go with DNA Sequencing?

CRISPR-Cas9, Epigenetics and Gel Electrophoresis sit alongside DNA Sequencing in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CRISPR-Cas9EpigeneticsGel Electrophoresis

Is the DNA Sequencing poster free to download and print?

Yes. DNA Sequencing downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the DNA Sequencing poster print at?

DNA Sequencing is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of DNA Sequencing loses nothing.Printing guide
