Mitosis is: a Process of cell division
a 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.
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.
cell division vocabulary
Transcription: 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 parts
Regulatory 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 numbers
Review of cell division vocabulary
Cell 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
Meiosis: 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
Cancer: 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.
