1. If you unwrap all the DNA you have in all your cells, you could reach the moon 6000 times!
2. Our entire DNA sequence would fill 200 1,000-page New York City telephone directories.
3. It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome.
4. We eat DNA every day.
5. Many things can cause mutations, including UV irradiation from the sun, chemicals like drugs, etc.
6. If all three billion letters in the human genome were stacked one millimeter apart, they would reach a height 7,000 times the height of the Empire State Building.
, Karissa Good.
Over 99% of our DNA sequence is the same as other humans
(same site as karissa)
1. If the total DNA from one person were laid in a straight line, it would stretch to the sun and pack 30 times! (It is over 93 million miles from Earth to the sun)
2. If the human genome was a book, it would be equivalent to 800 dictionaries.
3. Genes make up only 2-3% of the human genome.
- Rachel Kauffman
1. It takes about 8 hours for one of your cells to completely copy it's DNA
2. It would take 57 years to recite your ATCGs at a rate of 100 per minuet if you started tomorrow morning.
3. You could fit one million threads of DNA across the period at the end of this sentence.
4. If the genome was a book it would be as long as 800 dictionaries.
1. There are three billion (3,000,000,000) base pairs in the DNA code within each cell.
2. Humans have approximately 30,000 genes.
3. Human DNA is 98 percent identical to chimpanzee DNA.
4. Every second, Human Genome Project computers decode 12,000 letters.
- Jen Xu
If you were to start reciting the order of the ATCGs in your DNA tomorrow morning, at a rate of 100 each minute, 57 years would pass before you reached the end.
If you were to stretch out the DNA from those 46 chromosomes in one cell and lay it end to end, it would be over 2 yards in length
It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome.
4. Humans are 99.9% genetically identical - only 0.1 of our genetic make-up differs.
Less than 2% of the total DNA carries instructions to make proteins. The rest is misleadingly called ‘junk’ DNA, because it is a hodge-podge of sequences that does not seem to code for anything.
= - Eliza Nafziger
Our genes are remarkably similar to those of other life forms. For example, we share 98% of our genes with chimpanzees, 90% with mice, 85% with zebra fish, 21% with worms, and 7% with a simple bacterium such as E. coli.
Human beings share 7% of genes with E. coli bacterium, 21% with worms, 90% with mice and 98% with chimpanzees.
1000 cell nuclei
could be squeezed into a period mark at the end of a sentence.
There is genetic proof indicating that
the Sans are one of oldest peoples in the world.
They may well be the most ancient, and are considered to be a “genetic Adam”.
One out of every 180 children
is born with a chromosomal abnormality. The result of the most common abnormality is Down's syndrome.
A genetic study is being done on an African ethnic group
. They have an unusually
high birth rate of twins.
of the human genome contains information for the formation of proteins.
All the rest are the so called non-coding regions
because it is still not known what their specific function is.
In a single human cell there are between 10,000 and 100,000 coded messages known as genes. If all the directions contained in all these genes were written down, the words would fill the equivalent of 10,000 volumes of the Encyclopaedia Britannica.
One in six people has the most vulnerable genetic make-up and weighs an average 3 kilograms more than those with the lowest risk. They also have 15 percent more body fat.
Chromosomal disorders affect about 7 of 1000 live-born infants and account for about half of all spontaneous first-trimester abortions.
1. About 1 in 180 babies is born with a chromosome abnormality. The most common is Down syndrome, followed by Fragile-X syndrome.
2. There are over 200 different types of cells in the human body
3. 3% of the US population has an intellectual disability.
4. There are approximately 23,000 genes in the human genome.
5. There are thought to be about 3 billion base pairs in the human genome.
Chromosomal disorders can involve duplication, loss, breakage, or rearrangement of chromosomal material.
7. It takes about 8 hours for one of your cells to completely copy its DNA.
8. If the total DNA in one person were laid in a straight line, it would stretch to the sun and back over 30 times.
9. You could fit one million threads of DNA across the period at the end of this sentence.
1. Yeast has 6,000 genes while the average human has 30,000.
2. We still don't know the function of over 80% of human DNA.
3. About 1 in 180 babies is born with a chromosomal abnormality or mutation.
4. There are over 200 different types of cells in the human body.
5. Humans share 98% of DNA with monkeys, 90% with mice, 85% with zebra fish, 21% with worms, and 7% with bacteria.
6. All but 2% of DNA is considered "junk DNA" (the 2% non-junk DNA codes for proteins).
7. Siblings share 50% of genes while identical twins share 100%.
1.If unwound and tied together, strands of DNA from a human would be longer than five feet long but only 50 trillionths of an inch in width.
2.Scientists who study karyotypes are called cytogenetisists.
3.It takes about eight hours for one of your cells to completely copy its DNA.
4.You could fit one million threads of DNA across the period at the end of this sentence.
5.Humans are 99.9% genetically identical- only .01% of our genetic make-up differs.
6.Our genes are remarkably similar to those of other life forms.
7.If you unraveled all the chromosomes from all of your cells and placed the DNA end to end, the strands would stretch from the Earth to the moon about 6,000 times.
8.Finding every gene in the human body is like finding details on every person in every country of the world.
9.We still don't know the function of more than 80 percent of our DNA.
