Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells?...
Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...

Question 7 (1 point) What is the "chicken-and-egg" problem we face when trying to decide which came first - proteins or nucleic acids? early proteins and nucleic acids were very similar to each other. proteins and nucleic acids are always present together at the same time. nucleic acids cannot replicate without proteins, and proteins cannot be made without nucleic acids. O proteins and nucleic acids probably looked very different before the origin of life.
