The human haploid DNA, that is the DNA contained in a human gamete, is 3.3 billion base pairs long. So the DNA of a human contains 6.6 billion base pairs. now the distance between two base pairs in a DNA helix is 0.34 nm. therefore the length of the DNA double helix in a single human cell would come to about 2.2 m, approximately. Nature has devised its own ways to package such a long DNA strand in the nucleus of every human cell, which is so tiny when compared to the length of the DNA.
-they are pretty tiny
Chromosomes vary in size, but the DNA would generally be a few cm (inches). The total length of one copy of all chromosomes is about 1 meter (a little over 3 feet). Since you have one copy from each parent, the total is about 2 meters per cell.
One point Eight Seven METERS LONG - all 23 Paired Chromosomes - [1.87 meters of chromatin jammed into a nucleus barely one micron across!].
Multiplied by the trillions of Cells in Our Bodies =!
The size of a typical human Cell is about ten microns across.
That makes one million Cells per cubic millimeter of Tissue.
A DNA molecule consists of two strands wrapped around each other like a ladder. The length of a single average human DNA molecule is about 3.4 Angstroms.
If a single molecule were stretched out it would be 1-3 meters long.
DNA is composed of two strands of DNA nucleotides.
DNA molecule is normally double stranded
2 strands in total I believe.
a DNA molecule has two paired strands. ~
DNA is made of 2 strands so when it replicates the strands separate and 2 new strands complete the old strands. leaving 4 strands making 2 sets of DNA, both sets of DNA consist of one old strand and one new strand.- Sierra A. Buchanan
If a single molecule were stretched out it would be 1-3 meters long.
10000 DNA strands.
The electricity pulls the polar DNA strands through the gel, and shorter DNA strands move farther because they are less inhibited by the gel. The gel acts as drag to separate the different length DNA strands, so different DNA creates specific dye bands.
DNA is composed of two strands of DNA nucleotides.
At the beginning of DNA replication there are two strands of DNA nucleotides.
This means the two strands of DNA are complementary.
The two strands of DNA are connected by hydrogen bonds.
Normally DNA and RNA are the same length. However RNA has only one half of the two usually duplicate genetic strands of DNA
DNA molecule is normally double stranded
2 strands in total I believe.
Scientificamerican has a lot of information on DNA strands. There are also books available on eBay or Amazon that also provides more information on DNA strands.
