#1 Prokaryote are considered to be the most primitive type of cells. With time these cells have undergone numerous changes - mutations, adaptations, natural selections to evolve into eukaryotes. These eukaryotic cells are more complex and prevalent than the prokaryotic cells.
#2 evidence for endosymbiotic theory. According to which chloroplast and mitochondria are prokaryotic endosymbiants:
these all points show that there is much similarity between prokaryotes and chlorplast and mitochondria.
Discuss the significant changes that are represented in the evolution of the prokaryote cell type...
4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...
42. Which statement is NOT true about DNA? a) DNA acts like an enzyme by binding amino acids together using dehydration synthesis. b) Before cells divide both strands must be copied and one is provided for each new cell cm RNA is copied from a piece of DNA termed a gene. d) DNA is not always copied perfectly. Mistakes, mutations, occur and result in changed proteins, e) DNA functions as code for the synthesis of proteins. 43. A section of...

<Problem Set 9a Question 4 4 of 5 > Part A - TUA: Uverview UUR HIDRL yur g pruun When scientists use CRISPR-Cas9 to make specific cuts to a genome, they have a goal they're trying to achieve. Ohen, they either want to modify the protein that a particular gene encodes, or they want to block production of a particular protein. Depending on the goal, they customize the SANA they insert into the cell. For the CRISPR-Cas9 system to modify...
