- Hello there! My name is Tiffany the Tulip! Right now I'm getting my morning Nitrogen so I can grow big and strong!
- Carbon Dioxide, Water, and Light give me energy. That also creates sugar inside me, which I eat! This is called Photosynthesis!
- One day, while Tiffany the Tulip was was performing photosynthesis, Sally the Stegosaurus came along and decided to have her breakfast...Tiffany the Tulip is now a tumbling through Sally the Stegosaurus's body.
- OMNOMNOMNOM!
- Because Sally ate Tiffany the Tulip, who was our getting her morning nitrogen, will become part of Sally's DNA in the form of nitrogen bases.
- Meiosis Prophase 1- each replicated chromosome pairs with its corresponding homologous chromosome, this forms a tetrad.
- Telephphase 1- the nucleur membrane forms around each cell cluster of chromosomes
- Anaphase 1- spindle fibers pull homolgous chromosome pair toward opposite ends of the cell
- Cytokinesis 1- formation of two new cells.
- Metaphase 1- paired homologous chromoseomes line up against the center of the cell.
- The main enzyme used in DNA replication is polymerase
- The codons that belong to Sally are being translated into amino acids! A polypeptide chain is forming! Oh no! There was a deletion! One of her nitrogenous bases have gone missing!
- Mitosis Prophase 2- their chromosomes, each consisting of two chromatids, become visible.
- Mataphase 2, Anaphase 2, Telephase 2, and Cytokinesis- the four final phases of mitosis are similar to meiosis. However, the result is four haploid daughter celss.
- Prophase 2
- Metaphase 2 & Anaphase 2
- Telephase 2
- Cytokinesis
- Through each generation, genes are shuffled and re-shuffled. Half of a baby's genes come from its father and half from its mother. The baby's parents in turn inherited half each of their genes from each of their own parents. One quarter of each person's genes therefore come from the grandparents. So how does this happen? Instead of containing the full complement of 46 chromosomes, each egg and each sperm has just half, or 23, chromosomes each. When they meet at conception the chromosomes pair up to again make up the full complement that now forms the genetic blueprint for the new individual. One of the 23 pairs of chromosomes are sex chromosomes, so gender is also determined at conception. Each egg carries an X chromosome and each sperm either an X or Y. If two X chromosomes combine, the baby will be a girl; if an X and Y chromosome combine, the baby will be a boy .
- Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
- Because Sally ate that Tulip and her DNA was changed, when she reproduced and crossed DNA's with her husband, their baby Stewie the Stegosaurus was born half human half stegosaurus!
- Stewie becomes less fit because he needs his mother to take care of him, but Dino mothers leave their young at an early age and human parents take care of their children until they are a bit older!
- Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
- Sadly, Stewie and this new species of Stegosaur did not last long. Due to not having the right amount of care needed and the right nutrients to survive, they quickly died off.
