“Deoxyribonucleic acid: an extremely long
macromolecule that is the main component of
chromosomes and is the material that transfers
genetic characteristics in all life forms,
constructed of two nucleotide strands coiled
around each other in a ladder like
arrangement with the sidepieces composed of
alternating phosphate and deoxyribose units
and the rungs composed of the perinea and
pyrimidine bases adenine, guanine, cytosine,
and thymine: the genetic information of DNA is
encoded in the sequence of the bases and is
transcribed as the strands unwind and
replicate.”
Basically, DNA contains genetics in all life
forms.
 The genetics in DNA is developed and
stored by the different combinations and
orders of stored information.

DNA transfers genetic information to your
cells. Cells divide, and usually copy the
DNA exactly how it is. Sometimes if it
doesn’t copy correctly, the cell either
dies or a mutation occurs.

Each single-stranded DNA fragment is
made up of four different coding
molecules, or base pairs, called
nucleotides: adenine (A), thymine (T),
guanine (G), and cytosine (C) that are
linked end to end. Each base on the
opposite strand specifically pairs with, or is
the complement of, the other: an A always
pairs with a T, and a C always pairs with a
G. A DNA molecule with the sequence
DNA is in the chromosomes. Humans
have 2 sets of 23 chromosomes.
 Parents contribute one complete set
each to the child and therefore the child
inherits one set from each parent so the
child contains DNA from each parent.

It all has to do with receiving DNA from
both parents. The offspring is a perfect
combination of each parent.
 The dad is fat, the mom is skinny, the
offspring is normal.
 The dad is brown and white, the mom is
white so the offspring is a light brown.

So basically, in the last slide each flower
had a dominant purple gene and
recessive white gene.
 As you can see, there is a 75% chance of
a purple flower in the outcome and a
25% chance of a white flower as the
outcome.
 This is the theory of recessive and
dominant genes.
