Inheritance and Variation

• NUCLEUS - controls and regulates

  the activities of the cells; contains the

  hereditary material.
• CHROMOSOMES containing

  genetic material.
• CHROMATIN- unraveled

  condensed of DNA
• CHROMOSOMES- highly

  condensed structure of DNA
• Deoxyribonucleic acid- is a long

  molecule that contains or unique

  genetic code; heredity material in

  humans and almost all other.
• GENES- functional unit of heredity

  found in chromosomes which are in the

  nucleus of a cell.

  a long segment of the

  chromosome/DNA that codes for a

  certain trait.
• Nucleic acids- are important

  macromolecule in the cell.
• DNA - Is called the blueprint of life

  Primarily for the storage of

  genetic information

  Passed from one cell

  generation to the next
• RNA - Converts

  information stored

  in DNA to form

  protein
• Messenger RNA

  brings information from the DNA

  in the nucleus to the protein

  manufacturring area, the

  cytoplasm.
• Ribosomal RNA

  hold tightly into the mRNA using its

  information to assemble the amino acids in

  correct order.
• Transfer RNA

  supplies amino acids to the ribosomes to be

  assembled as protein.
• Protein synthesis- are large comples molecules that are essential for normal functioning in

  the cell
• Amino Acids- are the building blocks of protein
• Protein synthesis

  Process of making proteins which involves transcription and translation.
• All living things are made up of cells.
• Inside the cell are smaller structure called organelles.
