MODULE 3 BIOLOGY

Explain, in detail, the structure of DNA. Describe the double helix structure, the bonds, the bases, etc. Use the description of a ladder to help you explain each part and how they fit together.
What is the difference between DNA and RNA? Discuss the process of transcription. Begin with the DNA ladder having two sides and end with the mRNA separating from the DNA.
What is translation? Explain the steps of translation starting with the mRNA and ending with protein synthesis.
What is meiosis? Explain in detail the stages of meiosis? Why is meiosis important?
What is a sex-linked trait? Give an example to and explain how sex-linked traits work. What is the difference between a sex-linked trait and a sex-influenced trait? Discuss at least two autosomal genetic disorders. What are the characteristics of the diseases? How they are inherited?

An electron micrograph of a cell shows a rigid cell wall, a cytoplasmic membrane, a nonmembrane bound nuclear area, and no endoplasmic reticulum or mitochondria. Explain why the cell is or is not each of the following: a human T cell, a virus, a bacterial cell, a yeast cell.

BIOLOGY ASSIGNMENT

NAME: Tadpole Experiments
INSTRUCTIONS: Experimental Procedures to test a hypothesis.
You have just purchased 30 tadpoles1] Design a simple experiment (5-10 steps “ONLY”, and each step should have “LESS THAN” 2 sentences) outlining the method to test a hypothesis of yours.
2] Your hypothesis must be based around “ONE” area mentioned in the brackets => (Environment, Cell Specification, OR Morphogenesis/Cell Adhesion).
3] Your hypothesis should be scientifically sound and it should be testable.
4] Turn yourself into a scientist here and have fun with it! Try to incorporate at least “ONE” type of control in your experiments.
5] One last thing. A designed experiment like this “CANNOT” have conclusions! So don’t make a conclusion of anything!
