Answer it !!!!!
■ How do histones acquire +ve charge ?
■How is the lenght of DNA usually calculated ?​

Answer 1

Answer:

A) Histones are positively charged proteins that wrap up DNA through interactions between their positive charges and the negative charges of DNA. Double-stranded DNA loops around 8 histones twice, forming the nucleosome, which is the building block of chromatin packaging.Histone Marks and Gene Transcription.

B) 10.5

The DNA double helix biopolymer of nucleic acid, held together by nucleotides which base pair together. In B-DNA, the most common double helical structure found in nature, the double helix is right-handed with about 10–10.5 base pairs per turn

The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.
