| Question | Answer |
|---|---|
| Genetic Code | The program of the cell. it is the way cells store the program that they seem to pass from one generation of an organism to the next |
| Transformation | When one string of Bacteria is transferred to another |
| Frederick Griffith | British Scientist who in 1928 studied bacteria. In his studies he found the process of transformation |
| Fredrick Griffith Experiment | Griffith injected mice with a diseased string of bacteria (it died), he injected mice with a safe string of bacteria (didnt die), and he injected mice with a string of bacteria that had been diseased but was killed by heat (it didnt die). |
| Fredrick Griffith Experiment cont.. | Next he inject mice with a mixture of live cells from a string of harmless bacteria and they developed a disease (died). |
| DNA | nucleic acid that stores and transmits the genetic information from one generation of an organism to another |
| Oswald Avery | In 1994 he led a group of scientists which studied RNA and DNA. In this he figured out DNA carried a genetic code. |
| Avery's Experiment | The scientists extracted juices and combined them with enzymes that destroy lipids, protiens and carbohydrates, they saw transformaton still existed |
| Bacteriophages | composed of DNA core and a protein coat. They attach themselves to the surface of bacterium and then inject a material into the bacterium |
| Alfred Hershey and Martha Chase | They wanted to learn whether the protein coat, the DNA, or both of these parts of the infecting virus was the material that entered the bacterium. |
| Nucleotides | a molecule made up of 3 basic parts: 5 carbon sugar, a phosphate group, and a nitron containing group |
| Adenine | A nitrogen base in DNA |
| Guanine | A nitrogen base in DNA |
| cytosine and thymine | pyrimidines |
| Rosalind Franklin | She looked at the DNA molecule and was the person to develop X-ray evidence or patterns. This X-ray pattern was from DNA and every pattern was different. |
| Shape of DNA | Double Helix |
| James Waston and Francis Crick | They discovered the shape of DNA (double Helix). They also created the first model of the double helix. |
| Base Pairing | The force that holds the two strands of the DNA double helix together. |
| Replication | The process in which DNA is duplicated to form another exact copy of itself before cell division |
| RNA | the nucleic acid that acts as a messenger between DNA and the ribosome and carries out the process by which proteins are made from amino acids |
| Uracil | Present in RNA instead of thymine |
| Transcription | the process by which a molecule of DNA is copied into a complementary strand of RNA. |
| Translation | The decoding of messenger RNA message into a polypeptide chain |
| Messenger RNA | brings information from the DNA in the nucleus out to the ribosomes in the cytoplasm |
| Protein Synthesis | The process of making proteins |
| Condon | 3 letter code word, specifies a particular amino acid that is to be placed in the polypeptide chain |
| Transfer RNA | carries amino acids to the ribosomes, where the amino acids are joined to the ribosomes, where the amino acids are joined together to form polypeptides |
| Ribosomal RNA | makes up major part of the ribosomes. |
| Anticondon | 3 transfer nucleotides on Messenger RNA |
