Mitosis is: a Process of cell divisiona type of cell division that results in two cells, each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Vocabulary:pg 147 Gene: A sequence of DNA that contains the information to make at least one protein Gene Expression: The process of using DNA instructions to make proteins. Genotype: Genetic makeup of an organism Phenotype: the physical qualities of an organism including observable or not observable traits Alleles: alternative versions of the same gene that have different nucleotide sequences. mitosisInterphase:
cell division vocabularyTranscription: The first stage of gene expression, during which cells produce molecules of messenger mRNA from the instruction encoded within the genes Translation: The second stage of gene expression reads mRNA sequences and assembles the corresponding amino acids to make a protein Messenger mRNA: the RNA copy on an original DNA sequence made during transcription RNA Polymerase: the enzyme that accomplishes transcription. RNA polymerase copies a strand of DNA into a complementary strand of mRNA Ribosome: the cellular machinery that assembles proteins during the process of translation Codon: a sequence of three mRNA nucleotides that specifies a particular amin acid Anticodon: The part of tRNA molecue that binds to complementary mRNA codon Transfer RNA (tRNA): A type of RNA that helps ribosomes assemble chains of amino acids during translation Genetic Code: The particular amino acids specified by particular mRNA codons
EVery Gene Has two partsRegulatory Sequence: the part of a gene that determines the timing, amount, and location of protein produced. Coding Sequence: The part of the gene that specifies the amino acid sequence of a protein, Coding sequences determine the identity, shape and function of proteins. patterns in cell DIVISION: Fibonacci numbersReview of cell division vocabularyCell Division: the process by which a cell reproduces itself; it is normal and essential for growth and healing of tissues Mitosis: the segregation and separation of duplicated chromosomes during cell division Sister Chromatid: one or more identical DNA molecules that make up a duplicated chromosome following DNA replication Centromere: the specialized region of a chromosome where the sister chromatids are joined Cytokiness: the physical division of a cell into two daughter cells meiosisMeiosis: A specialized type of cell division that generates unique haploid gametes. Generates sex cells. Gamete: specialized reproductive cells that carry one copy of each chromosome, sperm are male gametes, egg are female gametes Haploid: having only one copy of every chromosome CancerCancer: unregulated cell division; cells divide inappropriately and accumulate, in some instances forming a tumor Chemotherapy: the treatment of cancer by the use of chemicals Most healthcare professionals now support the use of herbal medicine as a supplement to treatment, herbs and foods with high Vitamin C, Vitamin A, and antioxidant content may help with treatment.
