2264038520 | Nucleotide | A DNA building block of nucleic acid formed from a simple sugar, a phosphate group, and a nitrogenous base. | 0 | |
2264038521 | Mutation | A change in the nucleotide-base sequence of a gene or DNA molecule | 1 | |
2264039713 | Ribonucleic Acid (RNA) | A nucleic acid consisting of a chain of nucleotides that contain the sugar ribose and the nitrogenous bases adenine, guanine, cytosine, and uracil. RNA performs protein synthesis. | 2 | |
2264039955 | Replicate | To duplicate. The DNA molecule makes a copy of itself. | 3 | |
2264040543 | Double Helix | Double spiral; it describes the three-dimensional shape of DNA. | 4 | |
2314714544 | Adenine (A) | Nitrogenous base that pairs with thymine (T) during DNA replication. | 5 | |
2314731392 | Thymine (T) | Nitrogenous base that pairs with adenine (A) during DNA replication. | 6 | |
2314738919 | Cytosine (C) | Nitrogenous base that pairs with guanine (G) during DNA replication. | 7 | |
2314749980 | Guanine (G) | Nitrogenous base that pairs with cytosine (C) during DNA replication. | 8 | |
2314758106 | Chargaff's Rule | States that base pairs occur in equal amounts. The amount of (A) = the amount of (T), and the amount of (C) = the amount of (G). | 9 | |
2314851629 | X-Ray Diffraction | A process used by Rosalind Franklin to make images of DNA that helped reveal the structure of DNA | 10 | |
2314912350 | Complimentary | Refers to the copied DNA strand, or he matching base of another base. (ex. for sequence ATGCT the complimentary strand is TACGA) | 11 | |
2315132658 | Ribosome | Cell organelle that is attached to ER, or floating freely in cytoplasm. Site of protein synthesis (Translation of the Genetic Code). | 12 | |
2315162420 | Gene | A segment of DNA on a chromosome that codes for a specific trait | 13 | |
2315166710 | Messenger RNA (mRNA) | RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell | 14 | |
2315170416 | Deletion | Change to a chromosome in which a fragment of the chromosome is removed | 15 | |
2315173558 | Substitution | A mutation in which a nucleotide or a codon in DNA is replaced with a different nucleotide | 16 | |
2315186478 | Insertion | A mutation involving the addition of one or more nucleotide pairs to a gene. | 17 | |
2315223984 | Mutagen | A chemical or physical agent that interacts with DNA and causes a mutation, or change. | 18 | |
2315228584 | Sickle Cell Disease | A human genetic disease caused by a recessive allele that results in the substitution of a single amino acid in the hemoglobin protein; characterized by deformed red blood cells that can lead to numerous symptoms. | 19 | |
2315240888 | Genetic Engineering | A technology in which the genome of a living cell is modified for medical or industrial use. | 20 | |
2315253867 | Finger Printing (DNA) | Identifies the unique patterns in an individual's DNA, does not involve fingerprints. | 21 | |
2315329192 | Clone | a group of genetically identical cells or organisms derived from a single cell or individual by some kind of asexual reproduction | 22 |
