|
|
Name the 4 possible bases on a DNA strand. |
Adenine Cytosine Guanine Thymine |
|
|
What is complementary base pairing? |
When the nucleotides form the DNAstructure the bases pair up with their corresponding partner. |
|
|
What are the base pairings? |
Adenine with thymine Cytosine with guanine |
|
|
What determines the sequence of amino acids? |
The sequence of bases. |
|
|
What is messenger RNA (mRNA)'s function? |
to carry the complementary copy of the code from DNA, in the nucleus, to the ribosome, in the cytoplasm. |
|
|
What are proteins made up of? |
Amino acids |
|
|
what do amino acids determine? |
The proteins shape, function and molecular structure. |
|
describe step 1 of protein synthesis |
mRNA copies its complementary DNA strand. |
|
describe step 2 of protein synthesis |
The mRNA leaves the nuclear pore and travels to the ribosome in the cytoplasm. |
|
describe step 3 of protein synthesis |
The bases from the mRNA instruct the ribosome which amino acid to use to form the protein. |
