|
||||||
|---|---|---|---|---|---|---|---|---|
| nucleic acid | macromolecule used to store genetic information | DNA or RNA
🗑
|
||||||
| deoxyribonucleic acid | genetic material that organisms inherit from their parents | DNA - contains deoxyribose sugar
🗑
|
||||||
| nucleotide | the building block of nucleic acids - made of a sugar, phosphate group, and nitrogen base | nucleotides make up DNA; they are the "letters" of the genetic code as well as the "backbone" of DNA
🗑
|
||||||
| nitrogen base | adenine, theymine, guanine, and cytosine | A,T,C,G - the "letters" of the genetic code
🗑
|
||||||
| Chargaff's Rule (Base Pairing) | the percentage of A is equal to the percentage of T, and the percentage of G is equal to the percentage of C | A binds with T, C binds with G = base pairing
🗑
|
||||||
| James Watson and Francis Crick | scientists who figured out the shape of DNA as a double helix | double helix scientists
🗑
|
||||||
| chromosome | threadlike structure of DNA and protein that contains genetic information; in eukaryotes, chromosomes are found in the nucleus; in prokaryotes, they are found in the cytoplasm | chunks of DNA
🗑
|
||||||
| histone protein | proteins that DNA is wrapped around; help to condense the overall size of DNA, allowing it to fit in a smaller area | "beads on a string"
🗑
|
||||||
| gene | sequence of DNA that codes for a protein and thus determines a trait; factor that is passed from parent to offspring | the parts of DNA that determine our traits
🗑
|
||||||
| DNA replication | process of copying DNA prior to cell division | copying DNA
🗑
|
||||||
| DNA polymerase | principal enzyme involved in DNA replication | enzyme (ends in "ase") that copies DNA
🗑
|
||||||
| semi-conservative | a term used to describe the copying of DNA, since half of the original DNA is used as a template to create the new DNA strand | half old, half new
🗑
|
||||||
| ribonucleic acid | single-stranded nucleic acid that contains the sugar ribose | RNA; used to make proteins
🗑
|
||||||
| transformation | process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria | bacteria became deadly because they transformed - Frederick Griffith's experiment
🗑

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.
