Created the Grand Canyon National Game Preserve and killed the deers predators.
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
Through crossing over during meiosis. In eukaryotic cells (us), there are these things called Histone proteins. TONS of these wrap around and form what eventually will be a chromosome in the nucleus of the cell. These chromosomes contain genes which contain genetic information in the form of DNA. If a trait is sex linked it will pass through to the offspring by meiosis, specifically during crossing over when homologous chromosomes exchange genetic information.
