DNA and the production of proteins Flashcards
what is DNA ?
Deoxyribonucleic acid. a molecule found in all life on earth.
what is genetic code?
The sequence of bases on a DNA molecule that is different for all living things.
what is double stranded?
each DNA molecule is compose of two strands.
what is helix?
the twisted shape of the DNA molecule.
what is complementary ?
only A matches with T with G.
what is base?
the part of DNA that forms the genetic code.
what is Adenine ?
it base in DNA.
what is Thymine ?
it a base in DNA.
what is is Guanine?
it a base in DNA.
what is Cytosine?
it is base in DNA
what is gene?
A section of DNA that codes for a protein.
what is mRNA?
A molecule which carries a complementary cope of the genetic code from the DNA, in the nucleus, to as ribosome .
what go with Adenine ?
it is Thymine
what go with cytosine ?
it is Guanine .
where is chromosome are located?
in the nucleus of plant , animal and fungal cells. bacteria have one single circular chromosome and plasmids.
what is twisted shape of DNA is called?
it is call double helix.
what is complementary cope?
it part of DNA gene is made in the nucleus , this is called messenger RNA (mRNA).
where dose mRNA go to ?
it travels to a ribosome to determine the order of amino acids used.
what dose m stand for in mRNA?
it stand for messenger.
describe the role of the mRNA in making proteins?
mRNA copy the order in DNA code then leaves the nucleus and travels to the ribosome . ribosome the amino acids are placed in the correct order . the amino acids are linked together to from a protein.
