6. (Answer this question using the neutral theory of molecular evolution) One of Charles Darwin's main ideas was that life evolves by natural selection, following a rule of "survival of the fittest." For example, if you look historically at giraffes, it is hypothesized that those with taller necks tended to be selected for evolutionarily because they could reach more food high up in trees. When we consider DNA, the same principles of natural selection apply. Those DNA regions that have...

1. What would happen to a gene if the stop codon (UAA, UAG, or UGA) were mitated so that the first position in the codon became a “C” (CAA, CAG, CGA)? a) the protein product of the gene would be similar than normal b) either the immature RNA transcript or the mRNA will be degraded by nonsense mediated RNA decay c) its mature messenger RNA would be lengthened d) its immature RNA would be lengthened 2. Without a promoter region,...

If a eukaryotic cell has synthesized a large quantity of a certain protein, you would know that all of the following had occurred prior to protein formation, except: A. Repressor proteins were likely bound to all of the enhancer sequences and proximal elements of the gene for this protein. B. A transcription initiation complex was formed at the promoter region of the gene for this protein. C. Chromatin remodeling occurred in the region of the chromosome containing this gene for...

TranslationOverview:The purpose of this activity is to help the students to understand how replication, transcription, and translation are connected. Students will use a sequence from a bacterial gene that confers resistance to antibiotics (carbapenems). They will be asked to apply the knowledge obtained in the class lecture to (1) find the promoter in the sequence, (2) determine the amino acid sequence of a fragment of the polypeptide, (3) "reverse translate" a fragment of the polypeptide, and (4) identify mutations in...
