|
||||
|---|---|---|---|---|---|
| Avery | results not accepted by most scientists, transformation prevented by DNA destroying enzymes, DNA was the genetic material
🗑
|
||||
| Hershey and Chase | added to Avery’s work, radioactive tracers, DNA stores genetic information
🗑
|
||||
| DNA | sugar is deoxyribose, double helix, made of nucleotides
🗑
|
||||
| Nucleotide | phosphate, sugar, nitrogen base
🗑
|
||||
| RNA | sugar is ribose, one strand, uracil instead of thymine, ESSAY=name and describe 3 types
🗑
|
||||
| Messenger | delivers information to ribosomes
🗑
|
||||
| Transfer | carries amino acids to mRNA
🗑
|
||||
| Ribosomal | makes ribosomes
🗑
|
||||
| Franklin | X ray diffraction, discovered helical shape
🗑
|
||||
| Wilkins and Franklin | first to suggest DNA was helix
🗑
|
||||
| Replication | occurs before cell division, one mistake every billion nucleotides, two complimentary strands unwind and unzip while being duplicated, ESSAY=describe process
🗑
|
||||
| Helicase | breaks hydrogen bonds, enzyme
🗑
|
||||
| DNA Polymerase | check for errors during replication, add nucleotides during replication
🗑
|
||||
| Translation | anticodon bonds to codon and releases amino acid into a chain, involves mRNA and tRNA, occurs at ribosomes
🗑
|
||||
| Genetic Code | same in all organisms, use table
🗑
|
||||
| Mutations | insertion, deletion, substitution
🗑
|
||||
| Insertion | a base is added
🗑
|
||||
| Deletion | a base is left out
🗑
|
||||
| Substitution | a base is put in place of another
🗑
|
||||
| Griffith | caused harmless bacteria to become deadly,
🗑
|
||||
| Watson and Crick | DNA is double stranded and twists into a double helix, established structure of DNA
🗑
|
||||
| Chargaff’s rule | A=T, C=G
🗑
|
||||
| Transcription | messenger RNA is produced,
🗑
|
||||
| Codon | nucleotide triplet specifies for specific amino acid
🗑
|
||||
| Ribosomes | 3 binding sites during translation
🗑

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.
