Please read it carefully and answer thequestions:
Q1: Each Student must find two types of differentiated cells- (1 animal, 1 plant)
(No repeats so first come first serve)
? Post
? An image of the cell,
? A quick description of the cell
? Answer this question "what makes that type of cell unique".
? Include a source link to your where you found your type of cell & information.
? Present
? To start the next class period each student will have 1 minute to present their cells.
As a class we will have a comprehensive list of differentiated cells.
Q2: How many genes do we have written into our DNA?
Q3:DNA Helicase is the blue donut shaped protein that does what?
Q4: Because DNA is antiparellel one strand must be copied backwards. As DNA polymerase creates loops of DNA and copies these sections called okazaki fragments. A specific molecular machine or enzyme called DNA ligase joins these fragmented sections of DNA together to a complete strand of DNA? Google to find they type of bond DNA ligase catalyzes.
Q5:DNA is only about 2 nanometers thick, but DNA is about 30 to 40 million nanometers long. How long is DNA in centimeters?
Q6:To keep the DNA organized and regulate access to the genetic code DNA is wrapped around what purple colored proteins?
Q7:There are approximately 37.2 trillion cells in a human body. Drew Berry says that roughly how many cells are undergoing the process of mitosis right now? (Dozens, Thousands, or Billions of cells).
Q8:What is the wisker like dynamic scaffolding that pulls the duplicated chromosomes to the opposite sides of the cell during cell division?
Q9:How can can errors in, or damage to your DNA (f not repaired) cause premature aging?
Q10:Why are some DNA mutations beneficial?
Q11:Defects in DNA repair are associated with many kinds of cancer. Cancer is when a cell loses control of its replication. How can a mistake in DNA cause cancer?
Q12:What was the goal of the Human Genome Project?
Q13:What makes you, you? Where do the instructions that make you, you come from? What are these instructions stored on?
Q14:What are the 4 main chemicals or nucleotide bases of DNA?
Q15:How many base pairs are in the human genome?
Q16:Nutritional experts say that eating 1/2 lb of meat a week is healthy but the average American eats 1/2 lb a day. How does this lead to micro-nutrient malnutrition?
