After decades of studying extraterrestrial organisms on Triton, you and your colleagues have developed a pretty good cladogram (not yet time-calibrated) of alien life, and have developed a good understanding of species ranges and distributions. Use no more than 2 sentences or bullet points per subpart. (a) One clade of aliens has significantly many orders of magnitude more putative species than any of its close relative clades. What is one potential hypothesis for this phylogenetic pattern that we discussed in class?- (b) You observe a strong latitudinal diversity gradient on Triton that is analogous to the one we find on Earth for many clades. Briefly describe this observation, and propose one explanation for this pattern

The effect might be due to the gene expression.

Explanation:

The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.

answer: 2

explanation:

yes

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
