Answer: The length of one turn of DNA is 34A˚ or 3.4nm.
DNA is the acronym for Deoxyribonucleic acid. It is a polymer that is consist of two polynucleotide chains. It carries genetic instructions for the functioning, growth, development, and reproduction of all organisms. In DNA, the repeating units are called Nucleotides. In humans, DNA is made up of approximately 3 billion base pairs and almost 99% of the bases are common in all people. It occurs in prokaryotes as circular chromosomes and in eukaryotes as linear chromosomes.
Summary:
What is the length of one turn of DNA?
The length of one turn of DNA is 34A˚ or 3.4nm. The double helix of DNA determines the strength of association between the two strands.
