CBSE Grade 12 — Biotechnology, in Hindi
CBSE Grade 12 Biotechnology: 90 of 90 topics written, 0 of the 7 in the open sample readable in Hindi. Counted from the register, not claimed.
In the register this course is cbse-grade-12-biotechnology. Cite that, never
the board and grade alone: two registries share every grade id and
number their lessons differently.
| What | How many | What that means |
|---|---|---|
| Topic slots registered | 90 | The season's shape, decided. A numbered slot is a container, not a lesson. |
| Topics written | 90 | Every slot has a heading. |
| Open to read without an account | 7 | Written, and readable by anyone. The rest of the season is written and withheld. |
| Written and withheld | 83 | Written, and not in the open chapter. This is not the same number as the slots that have never been written, which is why both are here. |
| Summaries in Hindi | 10 | 10 summaries, and NONE of them is in the open chapter — every one is on a topic behind the wall. |
| Short films | 14 | 1 on a topic anyone may read. Films are counted once for the course, not once per language, so this page cannot tell you which language a film speaks. |
| Slide pictures in Hindi | 0 | No deck has been rendered in this language. |
| Source documents filed | 90 | What a topic's words are generated from. One per topic, where it exists. |
What is open right now
These 7 topics are readable without an account, and every one of them is named here. None of them carries a summary in Hindi yet, so what you get is the heading and whatever film exists.
- Recombinant DNA (rDNA) — stitching DNA from different sources like mixing two recipes into one dish
- Gene Cloning — making endless copies of a useful gene, like photocopying notes before boards
- Cohen–Boyer Experiment — the moment scientists first “remixed” life in a lab
- Restriction Enzymes — molecular scissors that cut DNA at exact spots
- DNA Ligase — the glue that seals DNA fragments together
- Plasmids — tiny circular DNA rings acting like delivery trucks inside bacteria
- Sticky Ends vs Blunt Ends — jagged vs clean cuts that decide how DNA pieces join
The headings above are in English. The register holds one language of headings for this course, so a Hindi reader sees Hindi summaries where they exist and English headings throughout. Saying so is cheaper than letting you find out.
