How is the length of a DNA defined?
The length of DNA is usually defined as number of nucleotides (or a pair of nucleotide referred to as base pairs) present in it. This also is the characteristic of an organism.
What is the length of DNA with 23 base pairs?
Distance between two consecutive base pairs in DNA strand is 3.4 ˚A . Thus, length of a DNA strand with 23 base pairs = 3.4 x 23 = 78.2 ˚A .
How much DNA is in the human body?
The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome.
How do you find the length of a gene in base pairs?
Start with the Molecular Weight
you have in nanograms. 6.022 x 1023 = Avogadro’s number. Length is the length of your DNA fragment in base pairs. Just multiply by 1000 if you are working in kb.
What is the relative length of DNA?
A DNA molecule in a human chromosome can be up to 250 million nucleotide-pairs long; in contrast, most RNAs are no more than a few thousand nucleotides long, and many are considerably shorter.
What is the length of DNA having 44 base pairs?
The length of DNA having 44 bp is 149.6A°. As the distance between each pair in the DNA strand is 3.4A°. It is a helical structure with each helix at 10 bp.
