Cell Cycle

• Interphase - The longest phase of the cell cycle where the cell grows and prepares to divide
• Cell Cycle - a series of events that takes place in a cell as it grows.
• 2 STAGES OF CELL CYCLE

  Interphase

  Cell Division
• 3 STAGES OF INTERPHASE

  G1 - First Gap Period

  S - Synthesis Stage

  G2 - Second Gap Period
• M phase or Cell Division
• Genetics - a branch of biology the deals with the study of heredity and variation of organisms.
• Heredity - the passing of traits from parents to offsprings
• Variation - the differences between individuals in a population, which can be used to identify the presence of a particular gene.
• Chromosomes - long strands of DNA that carry genes and are found in the nucleus of a cell
• Chromosomes - the threadlike part or structure of the cell that carries heredity information in the form of genes
• Genes - the basic physical and functional of heredity, consisting of a segment of DNA that codes for a particular protein
• DNA (Deoxyribonucleic Acid) - the molecule that contains genetic instructions for an organism's development, function, and reproduction
• DNA or Deoxy Ribonucleic Acid
• DNA - the genetic material located inside the chromosome in the nucleus of the cell. Its helical structure consting of two strands
• Interphase - where the chromosomes are long and extended reffered to as chromatin
• M Phase - also known as cell division where the chromosomes become condensed or thickened.
• G1 phase - growth phase, cell grows initially; the synthesis of protein and RNA/Ribonucleic Acids occurs
• S phase - synthesis phase, DNA are synthesized thus replicating chromosomes in preparation for cell division
• G2 phase - gap phase, cell prepares for actual cell division; falls between S phase and M phase
• Genetics is a branch of biology the deals with the study of heredity and variation of organisms.
• Heredity refers to the passing on of traits from parents to offspring through genes.
• Variation refers to differences among individuals within a species.
