Test 1 1. Polypeptide starts on a free ribosome. In the first step‚ the signal sequence emerges from the ribosome and binds to the SRP‚ which stops further translocation until the SRP-ribosome-nascent chain complex can make contact with the ER membrane. The SRP-ribosome then binds to an SRP receptor within the ER membrane during step 2. In the third step SRP is released and the association of the ribosome with a translocon of the ER membrane occurs. These latter events are accompanied by the reciprocal

contain half as many chromosomes. Process by which new cells are made The process by which new cells are made is called mitosis. Mitosis is a type of cell division where one cell splits up into two new identical cells. Before a cell can divide it has produce copies of other organelles such as ribosome and mitochondria‚ as well as another nucleus and 46 more chromosomes. During mitosis the copies of chromosomes separate and the entire cell divides into two. One organelle which would need to be copied

Prokaryotic and eukaryotic cells are both vital to our world today. Prokaryotic cells are simple‚ yet the oldest‚ and were known to evolve around 3.5 billion year ago. Eukaryotic cells are more complex and have been said to appear on Earth 2.5 billion years ago. It is sort of like people or characters in movies. You see them one year and basically understand what they’re doing or going through and then a year or two from now they seem like they become more complicated to understand. That’s just

Using Bloom Taxonomy in the classroom is inviting students to think at higher levels‚ which is a way to encourage students thought processes. Being an approach to make sure an educator can challenge their students beyond the level of mere factual recall. In Bloom Taxonomy the levels increase in degrees of difficulty and students must be able to master the first level before the next can occur. In science you need to start a lesson plan by testing your students’ ability to recall learned factual information

Animals and plants have to go through mitosis and meiosis when reproducing. Animals and plants go through meiosis because both have sex cells and they go through mitosis to create more cells‚ so when people/plants/animals grow‚ it isn’t the number of cells‚ but the

Mastering Concepts 8.1 1. Explain the roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development
