| Replication | this process by which DNA is copied during the cell cycle
🗑
|
||||
| DNA Polymerases | a group of enzymes bond the new nucleotides together
🗑
|
||||
| Central Dogma | states that information flows in one direction, from DNA to RNA to protiens
🗑
|
||||
| RNA | ribonucleic acid, is the chain of nucleotides, each made of a sugar, a phosphate group, and a nitrogen base
🗑
|
||||
| Transcription | is the process of copying a sequence of DNA to produce a complementary strand of RNA
🗑
|
||||

🗑
|
||||
| Messenger RNA (mRNA) | is an intermediate message that is translated to form a protein
🗑
|
||||
| Ribosomal RNA (rRNA) | forms part of ribosomes, a cells protein factories
🗑
|
||||

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.
