Diameter of a dna molecule
WebThe genomes of Mimiviruses and Pandoraviruses, which are some of the largest known viruses, range from 1 to 2.5 Mb (1 Mb = 1,000,000 base pairs of DNA). Most viruses vary in diameter from 20 nanometres (nm; 0.0000008 inch) to 250–400 nm; the largest, however, measure about 500 nm in diameter and are about 700–1,000 nm in length. WebThe total length of DNA present in one adult human is calculated by the multiplication of. (length of 1 bp) (number of bp per cell) (number of cells in the body) (0.34 × 10 −9 m) (6 × 10 9 ) (10 13) 2.0 × 10 13 meters. That is the equivalent of nearly 70 trips from the earth to the sun and back. 2.0 × 10 13 meters = 133.691627 ...

The A and G are purines, and the C and T are pyrimidines. The two strands of DNA run in opposite directions. These strands are held together by the hydrogen bond that is present ...
WebNo, it is not possible to see a single DNA molecule with the naked eye because the diameter of the DNA double helix is only 2 nanometers, which is much smaller than the resolution of the human eye. so we can not see DNA molecule every human human eye can resolve objects that are around 0.1 millimeters in size, which is approximately … A-DNA is one of the possible double helical structures which DNA can adopt. A-DNA is thought to be one of three biologically active double helical structures along with B-DNA and Z-DNA. It is a right-handed double helix fairly similar to the more common B-DNA form, but with a shorter, more compact helical structure whose base pairs are not perpendicular to the helix-axis as in B-DNA. It was discovered by Rosalind Franklin, who also named the A and B forms. She showed that DN…
