| show | Nucleotides
🗑
|

| What are the four DNA nucleotides? | show 🗑
|
||||
| show | Guanine and Cytosine. Adenine and Thymine.
🗑
|
||||
| show | Adenine (A), guanine (G), cytosine (C), uracil (U).
🗑
|
||||
| show | Guanine and Cytosine. Adenine and Uracil.
🗑
|
||||
| show | Scientists label the carbons in the sugar from 1' to 5' based on their position in the molecule. The phosphate group is attached to the sugar at the 5' carbon
🗑
|
||||
| show | True.
🗑
|
||||
| show | Hydrogen bonds
🗑
|
||||
| What shape does DNA take? | show 🗑
|
||||
| show | RNA is single stranded, some RNA molecules form folded structures, and, like proteins, these folded RNA molecules perform various functions like catalyzing reactions and transporting molecules.
🗑
|
||||
| What charge is the DNA phosphate in the backbone? | show 🗑
|
||||
| True or False: DNA is not a polar molecule, so it cannot be easily dissolved in water, but dissolves in non-polar solvents such as alcohol. | show 🗑
|
||||
| show | In eukaryotic organisms, DNA is contained inside the cell nucleus. DNA is tightly coiled around proteins to form structures called chromosomes.
🗑
|
||||
| show | The result of coding information determined by DNA
🗑
|
||||
| Where is DNA found in prokaryotes? | show 🗑
|
||||
| show | True. Ex: Humans have 23 pairs of chromosomes, or 46 total; a dog has a total of 78, and the adder's-tongue fern a total of 1,260!
🗑
|
||||
| Where is genetic information located? | show 🗑
|
||||
| What are "coding" segments called? What do they do? | show 🗑
|
||||
| show | True
🗑
|
||||
| True or False: Different codons code for unique amino acids. Some amino acids may not be coded for by more than one codon. | show 🗑
|
||||
| How many different amino acids are there? | show 🗑
|
||||
| show | True
🗑
|
||||
| Explain transcription. | show 🗑
|
||||
| Explain translation. | show 🗑
|
||||
| During transcription, the enzyme RNA polymerase catalyzes the copying of base codes in a gene from DNA to a complementary strand of mRNA. Where does this strand go? | show 🗑
|
||||
| Ribosomes are made of another kind of RNA called ribosomal RNA (rRNA). What occurs here? | show 🗑
|
||||
| What does tRNA (transfer RNA) do? | show 🗑
|
||||
| How are amino acids linked together? | show 🗑
|
||||
| When does DNA replication begin? | show 🗑
|
||||
| show | True.
🗑
|
||||
| Which strand of the replication fork can be continuously be assembled? How does the other strand complete synthesis? | show 🗑
|
||||
| show | Leading and Lagging.
🗑
|
||||
| show | A genetic copy.
🗑
|
||||
| show | Amino Acids

||||
| What is the most inclusive component of an organism? | show 🗑
|
||||
| show | A sugar phosphate group and thymine.
🗑
|
||||
| show | Helicase

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.
