Question

Supercoiled structure of eucaryotic chromosome is explained by
A) Taylor model
B) Freese-Taylor model
C) Nucleosome model
D) Nebel model

Answer 1

Hello friend
Your answer is Taylor model

Answer 2

Supercoiled structure of the eukaryotic chromosome is explained by C) Nucleosome model.

• Nucleosomes are structures consisting of DNA and histone octamer.
• The negative charge on DNA helps in its coiling around the positively charged histone proteins.
• Such structures repeat themselves to give the appearance of beads on a string.
• The DNA coils and forms chromatin fibers and ultimately chromosomes.
• Nucleosomes are unique to eukaryotic cells and are absent in all the prokaryotes.
