| Question | Answer |
|---|---|
| Which scientist used chemical analysis to show that the adenine and thymine always occur in the same proportion of any given species? | Chargaff |
| Which scientist used X-Ray diffraction to take a picture of DNA and help determine its shape? | Franklin |
| Which scientists are credited with the discovery of the structure of DNA in 1953? | Watson & Crick |
| What type of mutation is stop codons? | nonsense |
| What type of mutation is when the amino acids are different? | missense |
| What type of mutation is when the amino acids are the same? | silent |
| What type of mutation is when all amino acids move? | frameshift |
| What is the "twisted" shape of the two sided ladder of DNA called? | double helix |
| What biomolecules does DNA contains instructions for producing? | proteins |
| What are the structures of a DNA nucleotide? | phosphate group, sugar, nitrogen bases |
| What is the bond that holds the nitrogenous base pairs together in DNA? | hydrogen bond |
| Where does DNA replication take place? | nucleus |
| What is the overall goal of translation? | use the mRNA to make proteins |
| What is the end result of DNA replication? | two genetically identical strands |
| What is the result of transcription? | one strand of mRNA |
| What RNA nucleotides bond together? | A-U, T-A, C-G |
| Where does transcription take place? | nucleus |
| What is the goal of transcription? | copy genetic information from DNA to mRNA |
| Where does translation take place? | ribosome |
| What is the role of mRNA? | carries instructions from DNA to the ribosomes. |
| What are the non-coding portions of DNA called? | introns |
| How are codons and anti-codons related? | an anticodon on tRNA connects with a codon on mRNA (complimentary) |
| In order for proteins to be produced, what sequence must occur? (central dogma) | DNA-mRNA-protein |
| What are the three steps to DNA replication in order? | DNA unzips, an enzyme matches up base pairs, 2 new DNA strands form |
| What is the sugar molecules of DNA? | deoxyribose |
| What makes up the backbone of a DNA strand? | phosphate and deoxyribose sugar (bond together forming the side of the helix) |
| What does the order of amino acids determine? | the type of protein that will be made |
| What is a codon? | three bases that code for one amino acid |
| Why is protein synthesis important? | proteins perform important functions for our body |
| What is the function of tRNA? | transfers amino acids to the ribosome |
| When is it necessary for the genetic information to be copied? | every time a cell divides |
| What are the three parts of a nucleotide? | phosphate, deoxyribose sugar, nucleic acids (nitrogen bases) |
| What is a clone? | an identical copy because the genetic material would be the same |
| What is gene regulation? | the ability to turn genes on and off |
| How many hydrogen bonds are formed by A and T? | 2 |
| How many hydrogen bonds are formed by C and G? | 3 |
| What is the mRNA similar to? | instructions |
| What is the rRNA similar to? | factories |
| What is the tRNA similar to? | delivery truck |
| What is a DNA polymerase? | enzymes that bond nucleotides together (detects errors) |
| What unzips the double helix by breaking multiple hydrogen bonds? | helicase |
| Which molecule was coded for by the longest piece of DNA? | a protein with 25 amino acids |
| What is the goal of DNA replication? | make identical copies of DNA for cell division |
| Why does transcription and translation can occur simultaneously in prokaryotic cells but not in eukaryotic cells? | prokaryotic cells lack a nucleus to separate the two proccesses |
