|---|---|---|---|---|---|
| The part of the molecule for which DNA is named is the | sugar
🗑
|
||||
| In order to fit within a cell, DNA becomes more compact by | wrapping tightly around histones
🗑
|
||||
| Mitosis is the process by which: | the nucleus is divided into two nuclei
🗑
|
||||
| The attachment of nucleotides to form a complementary strand of DNA during replication is accomplished by | DNA polymerase
🗑
|

| Who built models that demonstrated that: DNA is made of two strands that twist into a double helix. | Watson and Crick
🗑
|
||||
| Molecules of DNA are composed of long chains of | nucleotides
🗑
|
||||
| The amount of guanine in an organism always equals the amount of: | cytosine Base pairing rules: C with G / A with T
🗑
|
||||
| The region of the chromosomes where two sister chromatids are held together is called a | centromere
🗑
|
||||
| As a result of mitosis, each of the two new cells produced from the parent cell during cytokinesis are: | exact copy of all the chromosomes present in the parent cell.
🗑
|
||||
| True or False, In DNA replication, the two new DNA molecule has two newly-made strands. | False
🗑
|
||||
| During DNA replication, a complementary strand of DNA is made from each original DNA strand. This, if a portion of the original strand is CCTAGCT, then the new strand will be: | GGATCGA
🗑

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.
