Tidak perlu latar belakang biologi
Pelajari gene editing, dari nol
Serangkaian panduan singkat: apa itu DNA, apa itu gen, bagaimana CRISPR menemukan dan mengubah suatu sekuens, lalu metode-metode lanjutan yang hadir setelahnya. Baca berurutan atau langsung loncat ke mana saja.
24 panduan. Setiap panduan dibuka dengan jawaban dalam bahasa sederhana, lalu masuk lebih dalam. Analogi digunakan secara bebas — dan setiap analogi disertai catatan tentang di mana tepatnya analogi itu tidak lagi berlaku, karena analogi yang setengah dipahami adalah awal dari sebagian besar kesalahpahaman tentang bidang ini.

What is a gene?
A gene is a stretch of DNA that carries the instructions for making one particular thing the cell needs — usually a…

What is a chromosome?
A chromosome is one very long DNA molecule packaged with proteins; humans normally have 46, in 23 pairs.

What is a genome?
A genome is the complete set of genetic instructions in an organism — every chromosome, every gene, and everything in…

What is RNA?
RNA is DNA's working copy — a temporary, single-stranded version the cell makes when it needs to use a gene.

What is a mutation?
A mutation is a change in DNA sequence. Most do nothing, some cause disease, and a few are beneficial.

What is gene editing?
Gene editing is changing the DNA sequence already inside a living cell, at a chosen location.

How CRISPR works, step by step
A guide RNA finds the target, the Cas protein cuts, and the cell's repair machinery makes the actual change.
Panduan · 4 menit baca
What Cas proteins do
Cas proteins are the machinery of the CRISPR system: they carry the guide, search the genome, and cut what matches.
Panduan · 4 menit baca
What guide RNA does
The guide RNA is the address. It carries a short sequence matching the target and holds the Cas protein in place.

How cells repair DNA — and why it decides the edit
The cell, not the editor, makes the change. Which repair pathway it uses determines what you actually get.
Panduan · 5 menit baca
What off-target editing means
An off-target edit is a change made somewhere other than the intended site, because the guide tolerated a mismatch.

Ex vivo and in vivo editing
Ex vivo means editing cells outside the body and putting them back; in vivo means editing them where they are.
