How is DNA Packaged into Chromosome? | Introduction to Nucleosome, Chromatin & Chromosome

This video provides a tutorial on the process of DNA packaging into chromosome. The packing of DNA involves the formation of nucleosome and chromatin. Nucleosomes are a complex of DNA and histone proteins, resembles a structure of beads on a string. Tightly packed nucleosomes form 30 nm fibers, nucleofilament. Further condensation of nucleofilaments form long DNA loops called chromatin fiber. Loops of heterochromatin further results into the formation of minibands, which then stacked in a central axis to form the chromosome.

The following topics are covered in this lesson,

1. Nucleosome
2. Histone octamer
3. Nucelofilaments
4. Euchromatin
5. Heterochromatin
6. Minibands of chromosome
7. Chromosome

Since I have been a student of molecular biology I swear that there is The Creator of such a complex thing about which we are struggling to understand. To have a working mechanism every step has to b put into its own place at one go. It is timeless and evolution is an illusion created by humans.

OMG u really and totally sound like Samantha .... Telugu viewers seriously just close ur eyes...listen her voice nd imagine Samantha 😂....btw nice explanation lol❤

This is an amazing video, thank you<3

Mdm plz make video on DNA damage and repair

Thank you so much for the video! I found in many other sources that a 30-nm fiber is actually the solenoid-like loops of 10-nm fiber (string with beads), so this is also coiled (not uncoiled as mentioned in the table) structure, right?

your voice is very low you could up your voice a little bit
