Attached are the 3 extra credit assignments that have been available since last week. Each extra credit assignment can replace a quiz, homework, or classwork grade. Extra credit assignments are to be turned into the basket when they are completed. Answers must be well thought and supported with the information we have learned in class. If you do not understand, simply come see me. Refer to the notes below for support. Last day to turn in extra credit assignments is THIS Friday (3/14)
- DNA is a double-stranded molecule.
- DNA strands are connected by complementary base pairs.
- In DNA, the base A always pairs with T. The base G always pairs with C.
- Each strand serves as a template for the other.
- Following the rules of base-pairing, we can easily create a new strand of DNA by separating the strands, and using each as a template to synthesize the complementary strand.
- DNA is a universal code for life. DNA is found in all living things.
- The sequence, or order of the genetic code is what gives diversity to life.
- RNA is a single stranded molecule that can be synthesize from DNA.
- In RNA the bases are G C A and U
- There is no T in a strand of RNA, instead there is U.
- RNA G will attach to DNA C. RNA C will attach to DNA G. RNA A will attach to DNA T. RNA U will attach to DNA A.
- Mitosis is cell division that creates identical cells with identical DNA
- Mitosis is involved with growth, repair, and asexual reproduction.
- Meiosis is cell division that creates gametes (sex cells) with a unique half of genetic material.
- Meiosis is involved with the production of sperm and egg ONLY.
- Genetic recombination occurs during meiosis and makes each sex cell unique.
