On a planet other than earth, an organism has DNA with a left handed double helix with a rise of 0.61 A and a helical pitch of 9.76 A. When the DNA wraps around a histone 181 bases of DNA surround the histone and each nucleosome is separated by 121 bases of DNA. How many bases are found in a single pitch ( one turn of DNA ) ?
The Z-DNA is left handed double helix other than the earth it having 12 basepaires or 24 bases for in single pitch.
On a planet other than earth, an organism has DNA with a left handed double helix...
Which of the following is NOT a characteristic of a double-stranded DNA helix. Question 22 options: The width of the helix is 20 Angstroms. Bases are separated by 10 Angstroms. The length of one helical turn is 34 Angstroms. All these statements are true.
