"Every million "letters" (nucleotides) take up a linear distance of only 3.4 × 10E5 nm
(0.034 cm)....The [haploid] human genome...contains about 3 x 10E9 nucleotide pairs, organized
as 24 chromosomes (22 different autosomes and 2 different sex chromosomes), and thus consists
of 24 different DNA molecules - each containing from 50 × 10E6 to 250 x 10E6 nucleotide pairs
of DNA. DNA molecules of this size are 1.7 to 8.5 cm long when uncoiled, and even the slightest
mechanical force will break them once the chromosomal proteins have been removed."
Thus, using the conversion factor of 0.034 cm per million (10E6) nucleotides, the uncoiled length
of the total human genome would be approximately 102 cm, or 40 inches. This is pretty impressive
if you consider that "A typical [dipoid] human cell thus contains ...about 6 × 10E9 nucleotide
pairs of DNA....By comparison, 6 x 10E9 letters..would occupy more than a million pages [of a
typical book].", as described in the Molecular Biology of the Cell.

What is allelic ladder?
An allelic ladder is a set of DNA fragments with known sizes used as a reference in gel electrophoresis to estimate the size of unknown DNA fragments. It helps in determining the size of DNA fragments based on their migration distance in the gel relative to the ladder's fragments. This is commonly used in DNA fingerprinting and genetic analysis.
What is the relative size of the outer planets?
the relative size of the other planet is Jupiter, Saturn and Uranus.
How does the DNA end up sorting itself in the gel?
If by the gel you mean in an electrophoresis test, then the DNA sorts itself out relative to the size of the DNA molecules. The shortest being closest to the positive end, and the longest near the negative end.
Which terrestrial planet has the largest core relative to its overall size?
Mercury has the largest core relative to its overall size among the terrestrial planets. The core makes up about 85% of Mercury's radius, compared to about 55% for Earth's core size relative to its radius.
Use of agrose in DNA isolation?
Agarose gel is used to separate DNA fragments based on size during electrophoresis. Agarose forms a matrix through which DNA molecules move under an electric field. This helps in visualizing and analyzing DNA samples by separating them according to their size.

What is meant by relative size when choosing a font size?
Relative size is an option in the style tab. It means that the size should be relative or correspond to the others.
What is the definition for the word relative size?
Relative means" in relation to" or "compared to". Relative size describes how an object appears next to another object. Mt. Rushmore's relative size is huge compared to a mouse. But Rushmore's relative size is very small compared (relative) to the universe.
How to interpret agarose gel electrophoresis results with DNA ladder?
To interpret agarose gel electrophoresis results with a DNA ladder, compare the bands of your sample DNA to the bands of the ladder. The ladder contains known DNA fragment sizes, allowing you to estimate the size of your sample DNA fragments based on their position relative to the ladder bands. The closer the sample bands are to the ladder bands, the more accurate the size estimation.
What is the relative size of the outer planets?
the relative size of the other planet is Jupiter, Saturn and Uranus.
What is relative population size?
Relative population size is the size of an area's population as it compares to similar areas' populations. For example, the relative population size of a country would be what rank it had compared to the population of other countries.
How is the size of DNA fragments determined during gel electrophoresis?
During gel electrophoresis, the size of DNA fragments is determined by comparing their migration distance in the gel to a standard ladder of known fragment sizes. The smaller fragments move faster and farther through the gel than larger fragments, allowing for their size to be estimated based on their position relative to the ladder.
What does the relative size of the circles and dots mean?
relative size retaining to a map or globe basically means the same... if you had a large grape... and a small grape that were the exzact same size and shape... they would have relative size... only because they are alike...
Is a bear the closest relative to a dog by DNA?
Bears are from the family ursidae, while dogs are from canidae, making their closest relative the dingo.
What is the Relative size of NaCl?
The term "size" has no sense in this context.
What is the relative size of great Britain?
It's about the size of Idaho.
What is the purpose of the ladder marker DNA?
DNA passes through a gel at different speeds depending on its size. The purpose of the ladder marker of a DNA is to make the passing of DNA possible.
