How is the protein created from the mRNA sequence which reads AUGAUAGUGUAC different from the protein created from one that reads AUGAUAGUGUAG? A. The first has fewer amino acids than the second.
B. The first has isoleucine where the second has leucine.
C. The first has one more amino acid than the second.
D. The first has serine where the second has valine.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

"d.) carbon dioxide and hydrogen sulfide"

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
