DNA

DNA. Blueprint of life. DNA - DEOXYRIBONUCLEIC ACID. DNA contains the code, or instructions for building an organism and ensuring that organism functions correctly. Just like a builder uses a blueprint to build a house, DNA is used as the blueprint, or plans, for the entire organism.

  1. DNA Blueprint of life

  2. DNA - DEOXYRIBONUCLEIC ACID

  3. DNA contains the code, or instructions for building an organism and ensuring that organism functions correctly. Just like a builder uses a blueprint to build a house, DNA is used as the blueprint, or plans, for the entire organism.

  4. It is the chemical component of chromosomes, which are located in the nucleus of every cell. Stretches of DNA (or stretches of chromosomes) code for genes.

  5. a Gene is a segment of DNA that codes for a protein, which in turn codes for a trait (skin tone, eye color, etc…).

  6. The shape of the DNA molecule is a double-helix. The sides of the ladder are composed of alternating sugars (deoxyribose) and phosphates. The rungs of the ladder are composed of nucleotides.

  7. Adenine, Thymine, Guanine, Cytosine Nucleotides pair in a specific way - called the Base-Pair Rule Adenine pairs to ThymineGuanine pairs to Cytosine

  8. It takes about eight hours for one of your cells to completely copy its DNA.

  9. 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.

  10. 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 (provided that you did not stop to eat, drink, sleep, use the bathroom etc.)

  11. You could fit one million threads of DNA across the period at the end of this sentence.

  12. Humans are 99.9% genetically identical – only 0.1% of our genetic make-up differs.

  13. 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

  14. 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.

  15. If the total DNA in one person were laid in a straight line, it would stretch to the sun and back over 30 times (it’s 93 million miles from here to the sun)

  16. If the genome was a book, it would be the equivalent of 800 dictionaries.

  17. It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome. You would need 3 gigabytes of storage space on a computer to hold all of this
