Answer:
During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condenses into discrete chromosomes. The nucleolus also disappears during early prophase.
In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.
Answer:
The correct answer is "mutations to homologous genes".
Explanation:
The missing options of this question are:
A) morphology.
B) the pattern of embryological development.
C) biochemical pathways.
D) habitat and lifestyle choices.
E) mutations to homologous genes.
The correct answer is option E) "mutations to homologous genes".
Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.
Reduction
Reduction is the second step of the Calvin cycle which would be affected first by a lack of NADPH.
The Calvin cycle is the group of chemical processes that occur within the chloroplasts during photosynthesis . The three main steps in Calvin cycle are carbon fixation (Carboxylation), reduction, and regeneration of the starting molecule. In the reduction step, NADPH acts as a reducing agent which functions by transferring electrons that allow carbohydrates to be synthesized from carbon dioxide. During these step, there is transfer of two electrons and one proton to the phosphorylated compound by NADPH which produces one phosphate group to form the triose phosphates.
