I will say that the answer to your his question is letter A
DNA is copied during the Interphase
Answer:
Adaptive evolution
Explanation:
The radiation of finches in the Galápagos archipelago is the result of the natural selection process described by Darwin as adaptive evolution. Evolution is the process for which the organisms better adapted to its environment have more chances to survive and to reproduce, thereby leaving more offspring in the next generation.
Moreover, adaptive evolution refers to the mechanism for which species evolve by the emergence of advantageous mutations that are fixed through positive selection, thereby favoring the phenotypes that have higher adaptive fitness.
Answer:
<h2>Striated, smooth, and cardiac muscle cells contain vast numbers of cytoplasmic filaments that function during the contraction of these cells. ... The contraction of striated muscle cells shortens the muscle, which then moves the skeleton.</h2>
Answer:
Transcription is affected via the modulation of the concentrations of the different types of holoenzymes, so saturated promoters are only weakly affected by sigma factor competition. However, in case of overlapping promoters or promoters recognized by two types of sigma factors, we find that even saturated promoters are strongly affected. Active transcription effectively lowers the affinity between the sigma factor driving it and the core RNAP, resulting in complex cross-talk effects. Sigma factor competition is not strongly affected by non-specific binding of core RNAPs, sigma factors and holoenzymes to DNA. Finally, we analyze the role of increased core RNAP availability upon the shut-down of ribosomal RNA transcription during the stringent response. We find that passive up-regulation of alternative sigma-dependent transcription is not only possible, but also displays hypersensitivity based on the sigma factor competition.
