The Endosymbiont Hypothesis and the evolution of the Chloroplast and Mitochondria Dr Lynn Margulis is seen as the first person to have put forward the Endosymbiont Hypothesis which is based on a theory which explains the likely origin of the mitochondria and chloroplast (plants) in eukaryote organisms which we observe today. Dr Margulis received evidence from all over the world and from many scientific researchers and experiments‚ Margulis simply had to put all the evidence together to form her

WHAT IS RECOMBINANT DNA So what is rDNA? It stands for Recombinant DNA. Before we get to the “r” part we need to understand DNA. DNA is the keeper of all the information needed to recreate an organism. All DNA is made up of a base consisting of sugar‚ phosphate and one nitrogen base. There are four nitrogen bases‚ adenine (A)‚ thymine (T)‚ guanine (G)‚ and cytosine (C).The nitrogen bases are found in pairs‚ with A & T and G & C paired together. The sequence of the nitrogen bases can be

The mitochondria in our body has multiple important roles‚ such as regulating cellular movement ‚ making ATP‚ and converting the energy we get from food into energy that our body can use. When the mitochondria does not function properly‚ and the mtDNA: the mitochondria DNA has a mutation it can lead to severe and fatal diseases. A mutation in the mtDNA can cause certain organs with a high energy demand to stop working. MRT is implementing a new mitochondria into a women’s body by replacing the original

Cell Organelle Worksheet Organelle Nucleus Where found (plant/animal/both) In animals it’s in the center of the cell while in plants it’s found in the cytoplasm. What it does in the cell (functions) It maintains the integrity of the genes and controls the activities of the cell. Something that performs the same function in the “real world” It works like a CPU sending out messages.
