Lactic Acid Fermentation | Enzymes convert pyruvate into acid and skeletal muscles produce it to supply oxygen. |
Alcohol Fermentation | Converts pyruvate into ethyl and carbon dioxide. |
Sexual Reproduction | Requires two of the same species to produce offspring.
Offspring is genetically different. |
Asexual Reproduction | Does not require a mate to reproduce.
Creates offspring that is genetically identical to the parent. |
Malignant Tumors | Cancerous, it destroys healthy tissue. |
Benign Tumors | Non-cancerous, it does not spread. |
Differentiation | Process where cells become specialized. |
Crossing-Over | Chromosomal segments are exchanged between a pair of homologous chromosomes. |
Zygote | Contains 2n number of chromosomes. |
Genes | Chromosome that carries information for proteins for a specific trait. |
Alleles | Different forms of a single gene passed down from generations. |
Heterozyous | Two different alleles for a particular trait. |
Homozygous Dominant | Two dominant alleles that are expressed. |
Homozygous Recessive | Two alleles are the same with no dominant allele expressed. |
Phenotype | Physical characteristics of a allele pair. |
Genotype | Organism's allele pairs. |
Punnett Square | Predicts possible offspring of two genotypes. |
Dominant | Allele that is always expressed. |
Recessive | Allele that is only expressed if there is no dominant allele present. |
Gregor Mendel | Performed cross-pollination in pea plants. |
Genetic Engineering | Technology that manipulates DNA of one organism. |
Transcription | DNA code is transferred to mRNA in the nucleus. |
Translation | Translates protein. |
Codon | Three bases code in DNA or mRNA. |
Nucleotide | Made up of five carbon sugar, phosphate and nitrogenous base. |
