What is Cardiovascular System.
your heart pumps blood throught all you blood vessels.
What is a vervous System?

facts about genes, chromosomes, and proteins.
genes control the production of proteins in an organism's cells. PRoteins help determine the
size,shape, and other traits of an organism.
what are the DNA molecules?
adenine, thymine, guanine, cytosine ( A to T) (G to C)
what is the genetic code?
It specifies what type of protein will be produced.
DNA
IT produces RNA, its tymine and cytosine and its stays inside the nuclaus
RNA
it is out side the nucleas, uriule and cytosine.
RNA and DNA
they are both Adnine and Guanine
messanger RNA
sends messages to the trandfer RNA
transfer RNA
they read the messenge by pairing up three-letter codes to base on the messenger RNA
what is the first step of protein synthesis?
DNA "unzips" to direct the production of strand of messenger RNA.
what is the last step of protein sythesis?
the protein chain grows longer as each transfer RNA molecile adds an amine acid
what is a mutation?
a cell to produce and incorrect protein during protein sythesis as a resild, the organism's
train, or Phenotype, may be different...
how can mutations affect protein sythesis in cells?
it can calse the cell to use the incorrect protein. Sometimes is can be good or bad or have no
effect what so ever
whether a mutatuons is harmful or helpful depends partly on an organism's
environment
mutations can be source of genetic
veriaty
facts about mutations..
