Question

These laws have been used to establish chromosome theory as scientists examined visible chromosomes in meiotic cells. What are these two laws? points) (2) Gregor Mendel defined two fundamental laws of transmission genetics in the late 1800s. (3) Indicate in your diagram of meiosis on the first page how Mendel's laws are consistent with what we know about meiosis. In other words, indicate where Mendel's laws are occurring during meiosis. (2 points) (4) How many different nucleotides can be found in an mRNA molecule? What are the names of the nucleotides? 2 points) (5) How many different amino acids may be coded for by an mRNA? Name four examples of these amino acids, and list all of the codons for each of the four amino acids. (4 points) (6) Suppose that life is discovered in other parts of our solar system, and the same amino acids as are coded for by the mRNA found in these extraterrestrial forms of life. Surprisingly, the number of nucleotides in these alien cells differs from what is observed on our planet. a) Cells from the moon of Saturn have only two types of nucleotides. Does this have implications for the process of translation? What would be the minimum size for a codon? Explain the reasoning for your answer. (I point) b) Cells from Mars have only three types of nucleotides in their mRNA? Again, what would be the minimum size for a codon? Why? ( point) c) Cells from a moon around Jupiter have five different nucleotides in their mRNA. What would be the minimum size for a codon? Explain your reasoning. (1 point)

Explanation / Answer

1 Mendel had proposed two laws

First was law of independent assortment that is alleles from one trait behaves independently than alleles from another trait.

Second was law of segregation that says two alleles for a trait segregate during gamete formation and only one allele for a gamate is carried in a gamete.
