Cell Cycle & Cell Division - Mitosis - Part 1

Mitosis takes place in somatic cells and in germinal cells during multiplication phase. It is also known as equational division as the chromosome number is same in both the daughter cells and the parent cell.

Cell Cycle and Genes - Mitosis & Meiosis

Cell Cycle and Genes - Mitosis & Meiosis.
This is a teaser video. Watch the complete lecture in member's area at

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes.

Cell Divison Part 3~1

Mitosis: The Amazing Cell Process that Uses Division to Multiply! (Updated)

Updated Mitosis Video. The Amoeba Sisters walk you through the reason for mitosis with mnemonics for prophase, metaphase, anaphase, and telophase. Expand details to see table of contents.👇 Video handout here:

Table of Contents:
Why is Mitosis Important? 0:44
Why Don't You Want Cells Dividing all the Time? 2:00
Interphase (occurs before mitosis) 2:23
DNA and Chromosomes 2:55
Chromosome Replication 4:07
PMAT Mitosis Stages 5:30
Cytokinesis (actual splitting of cell) 7:30

We appreciate the feedback we get for what we need to clarify or should have added. Here is a clarification (also pinned in comments): (1) We mention mitosis as a type of cell division. To be specific, it's a division happening within the cell - in the nucleus. But we do not introduce the nucleus until later on in video. Mitosis is specifically the division happening of the nucleus whereas cytokinesis follows to do the actual splitting of the cell (mentioned at 7:30). (2) Our video is intended to focus on animal cells (as drawn) - specifically human cells - as we use human chromosome numbers. We wish we had clarified that more as we appreciate the feedback that the statements, Mitosis makes body cells. Meiosis makes gametes. has some big exceptions such as plants. (3) In metaphase, we do not draw a nucleus (6:09), because we mention it already has been disassembled. Disassembly of the nuclear membrane (envelope) occurs at the end of the previous stage. Many texts will state this is during prometaphase, a stage in between prophase and metaphase. In this short video, we do not include prometaphase. We only mention that the nucleus is no longer there by the time it's metaphase. (4) Notice our illustration in anaphase also includes a text box that says sister chromatids separate at 6:37. It's important to understand that chromosomes are moved away in anaphase, but as the text box notes, realize they are separated by the pulling apart of sister chromatids. This is especially important when comparing mitosis to meiosis I---as you can see our comparison video (which has more detail) here:

CELL CYCLE AND CELL DIVISION: MEIOSIS ORREPRODUCTIONDIVISION:Meioum means to diminish,The type of cell division, in which the chromosome number is reduced exactly to half is called meiosis. The term meiosis was coined by J.B. Farmer 1905.It occurs in reproductive cells of sexually reproducing organisms.The cells in which meiosis occurs are called meiocytes.In meiosis the chromosomes present in meiocyte is reduced to half in Meiosis- I. & these reduced chromosomes divided by mitotically in Meiosis-II. In this the mother cell divides into four daughter cells and these cells are unidentical when compared to their parent cell.Every organism has definite number of chromosomes in diploid condition 2n. All organisms begin their life form at zygotic stage. The zygote is formed by the fusion of gametes. Thus in diploid organisms every cell has 2 sets of chromosomes each acquired from the male and female gametes. Chromosomes with similar characters, uniform size & types belonging to parental sources are called homologous chromosomes. In the life cycle of diploid organisms, the chromosome number is reduced to half at one stage or the other. If not, at every fertilization the chromosome number would be doubled leading to abnormal number & causes unimaginable genetic disorders. Since the number of chromosomes is reduced to half, it is called reduction division.

2-1.1 - Chromosomes and Cell Division (Part 1)

What does your genetic information look like? We find out by diving inside the cell nucleus.

Cell Division

Paul Andersen explains how cells duplicate through the process of cell division. Prokaryotic cells (like bacteria) duplicate through a process of binary fission. Eukaryotic cells (like you) duplicate body cells through mitosis and create sex cells through meiosis.

Mitosis vs. Meiosis: Side by Side Comparison

After learning about mitosis and meiosis from our individual videos, explore the stages side by side in this split screen video by The Amoeba Sisters! Expand video details for table of contents. Vocabulary in this video includes chromosome, chromatid, haploid, diploid, crossing over, and homologous chromosomes.

Contents:
0:50 Intro to Mitosis/Meiosis
1:07 Starting Cells in Mitosis/Meiosis
1:20 Interphase (happens before mitosis and meiosis)
2:19 Mitosis/Meiosis I Split Screen
4:30 End of Mitosis
4:46 Meiosis II

Hope you enjoy our comparison! You can see our individual videos on mitosis and meiosis We also like to pin extra points/clarifications here. Crossing over in meiosis has a major role in genetically diverse offspring; however, Pinky learned in one of her graduate courses that mitosis crossing over- while very rare (likely why it's uncommon to see it in intro bio courses)- can occur. It can have a role in human cancer and loss of heterozygosity. While this unusual event is not discussed in this intro video, here is a further reading suggestion where you can learn more about it: .

Phases of mitosis:This animation demonstrates the stages of mitosis in an animal cell.

Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word mitosis means threads, and it refers to the threadlike appearance of chromosomes as the cell prepares to divide. Early microscopists were the first to observe these structures, and they also noted the appearance of a specialized network of microtubules during mitosis. These tubules, collectively known as the spindle, extend from structures called centrosomes — with one centrosome located at each of the opposite ends, or poles, of a cell. As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. This process ensures that each daughter cell will contain one exact copy of the parent cell DNA.


Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. For a complete description of the events during Interphase, read about the Cell Cycle.

Prophase: During this first mitotic stage, the nucleolus fades and chromatin (replicated DNA and associated proteins) condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information. Microtubules of the cytoskeleton, responsible for cell shape, motility and attachment to other cells during interphase, disassemble. And the building blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes.

Prometaphase: In this stage the nuclear envelope breaks down so there is no longer a recognizable nucleus. Some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined. Other spindle fibers elongate but instead of attaching to chromosomes, overlap each other at the cell center.

Metaphase: Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.

Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles.

Telophase: The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.

Cytokinesis: The spindle fibers not attached to chromosomes begin breaking down until only that portion of overlap is left. It is in this region that a contractile ring cleaves the cell into two daughter cells. Microtubules then reorganize into a new cytoskeleton for the return to interphase.
