What is the order of the renal tubules?
After leaving the renal corpuscle, the filtrate passes through the renal tubule in the following order, as shown in the diagram: proximal convoluted tubule (red: found in the renal cortex) loop of Henle (blue: mostly in the medulla) distal convoluted tubule (purple: found in the renal cortex)
What is the correct order of the stages in interphase?
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
What is the correct sequence for parts of the renal tubule quizlet?
Proximal convoluted tubule, descending limb of loop of Henle, ascending limb of loop of Henle, Distal convoluted.
What are the 3 stages of interphase and what happens in each stage?
There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.
What is the interphase of mitosis?
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
What are the names of the five phases of mitosis?
Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis – the process of dividing the cell contents to make two new cells – starts in anaphase or telophase.
When does a cell go through interphase before mitosis?
Interphase. Before a dividing cell enters mitosis, it undergoes a period of growth called interphase. Some 90 percent of a cell’s time in the normal cellular cycle may be spent in interphase. G1 phase: The period prior to the synthesis of DNA. In this phase, the cell increases in mass in preparation for cell division.
When does cytokinesis start and end in mitosis?
Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. In animal cells, cytokinesis is contractile, pinching the cell in two like a coin purse with a drawstring.
What happens to the mitotic spindle in telophase?
In mitosis, motor proteins carry chromosomes or other microtubules as they walk. In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place. The mitotic spindle is broken down into its building blocks.
