Mitosis and Meiosis
Testo Storyboard
- HI I'M CLARENCE AND I'M HERE TO EXPLAIN TO YOU THE 2 TYPES OF CELL DIVISION.
- HOW DO CELLS DIVIDE?
- DIVISION
- parent cell
- DNA replicates
- 2 DAUGHTER CELLS
- MITOSIS
- DURING MITOSIS, A CELL DUPLICATES ALL OF ITS CONTENTS, INCLUDING ITS CHROMOSOMES, AND SPLITS TO FORM TWO IDENTICAL DAUGHTER CELLS.
- BECAUSE THIS PROCESS IS SO CRITICAL, THE STEPS OF MITOSIS ARE CAREFULLY CONTROLLED BY CERTAIN GENES.
- MEIOSIS
- 4 DAUGHTER CELLS
- PARENT CELL
- DNA REPLICATES
- DIVISION
- 2 DAUGHTER CELLS
- MEIOSIS IS A PROCESS WHERE A SINGLE CELL DIVIDES TWICE TO PRODUCE FOUR CELLS CONTAINING HALF OF THE ORIGINAL AMOUNT OF GENETIC INFORMATION.
- THESE FOUR DAUGHTER CELLS ONLY HAVE HALF OF THE NUMBER OF CHROMOSOMES OF THE PARENT CELL - THEY ARE HAPLOID.
- THANK YOU FOR LISTENING.<3
