| Question | Answer |
| What does DNA store and transmit? | Genetic or Hereditary info |
| What is a nucleotide made up of? | - 5 carbon sugar -A phosphate group - And a nitrogen base |
| What is the base pair rule? | Certain nitrogen bases connect with eachother |
| What nitrogen bases match up with each other? | Adenine & Thymine; Cytosine & Guanine |
| What is the structure of DNA? | A double helix strand |
| What is the "backbone" of DNA composed of? | deoxyribose (sugar) & a phosphate group |
| What holds the Nitrogen bases together? | Hydrogen bonds |
| What are the names of the 4 Nitrogen bases? | Adenine, Thymine, Cytosine, & Guanine |
| What is replication? | The process of which DNA is copied |
| What is the first step of DNA replication? | "Unzipping" the double helix strand |
| Which enzyme is responsible for unzipping the DNA double helix? | DNA helicase (polymerase) |
| Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new DNA molecule? | Polymerase |
| Which enzyme is responsible or creating the covalent bonds that connect the sugar phosphate backbone of the new DNA molecules? | Ligase (polymerase) |
| Which is the 2nd step of DNA replication? | Use the original DNA as a template |
| Which is the 3rd step of DNA replication? | Pasting the DNA strand and making another one |
| Where is RNA *initally created*? | The nucleus, but it eventually leaves the DNA to take genetic info to the cytoplasm and the ribosome |
| What is the sugar of RNA? | Ribose |
| How many strands does RNA have? | 1 |
| What nitrogen base does RNA use thats different than DNA? | Uraril (RNA) / Thymine (DNA) |
| What are the types of RNA? | -mRNA -rRNA -tRNA |
| What is mRNA? | A type of RNA that takes genetic information from DNA to the ribosome to tell them which types of protiens to make |
| What does mRNA look like? | A stright line with nitrogen bases |
| What is rRNA? | Its a part of a ribosome |
| What is tRNA? | Takes amino acids to ribosomes to make protiens |
| What is transcription? | The making of RNA from DNA |
| What Does DNA polymerase create? | DNA (duh!) |
| What enzyme is required in transcription? | RNA polymerase |
| What is the first process of transcription? | RNA polymerase binds to DNA and seprates the strands |
| What is the second process of transcription? | RNA polymerase uses the one strand of DNA as a template |
| What is the shape of tRNA | A t like shape |
| What us the shape of rRNA | A blob like shape |
| Name the 2 purines | Adenine and Guamine |
| Name the 2 pyrimidines | Thymine and Cytosine |
| Why is DNA considered semi-conservitive | Because i has a new and old strand of DNA |
| What is transcription | The making of RNA from DNA |
| What is translation | The making of protiens from RNA |
| Which type of RNA is madr during transcription | mRNA |
