---|---|---|---|---|---|
complementary base pairing | the specific arrangement of bases in nucleotides (adenine with thymine, cytosine with guanine)
🗑
|
||||
DNA Helicase | an enzyme that unwinds the double helix of DNA
🗑
|
||||
DNA Polymerase | an enzyme that assembles the nucleotides on the DNA strands
🗑
|
||||
recombinant DNA | the combination of two or more different sources of DNA put together artificially
🗑
|
||||
replication | duplicating the strands of DNA
🗑
|
||||
semi conservative replication | creating two new strands of DNA which both have a strand from the original DNA
🗑
|
||||
anti codon | a sequence of three bases located on tRNA which complement three other bases on mRNA
🗑
|
||||
codon | a sequence of three bases located on mRNA that correspond to a specific amino acid attached to tRNA
🗑
|
||||
DNA sequence (genetic code) | the specific order of bases in DNA
🗑
|
||||
elongation | a step in translation where the tRNA brings in amino acids and forms a polypeptide chain
🗑
|
||||
environmental mutagen | induces a mutation (radiation, virus, chemicals etc)
🗑
|
||||
genetic disorder | a disorder that has been inherited through your genes (Huntington disease, Marfan syndrome)
🗑
|
||||
initiation | the starting codon on the mRNA that begins the process of translation
🗑
|
||||
messenger RNA (mRNA) | carries the blueprint for the structure of the protein that will be made, made from copying DNA
🗑
|
||||
mutation | changing the structure of the gene sequence in your DNA, caused by one single alteration
🗑
|
||||
termination | the stop codon on the mRNA that tells the protein to end
🗑
|
||||
transcription | the process of making RNA strands from copying the information from the DNA strands
🗑
|
||||
transfer RNA (tRNA) | in the cytoplasm where they bring the correct amino acid to the ribosome for translation to occur
🗑
|
||||
translation | the process where polypeptide chains are made with the aid of the ribosome, mRNA and tRNA
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
