Cell Cycle Story Assignment

By: Maria Galarza - Rojas
Biology
Period: 1
G1 Phase This is Blob. It is a human cell that is going through the cell cycle. Right now it is beginning mitosis and is in the G1 phase. At this point Bob is synthesizing its structural proteins and enzymes to perform its functions.

[pic]

S Phase Now Bob is in the S phase. Its DNA is being duplicated. Bob is going to wait for a long time. It usually takes 10 hours for all of the information to duplicate. All of the chromosomes are being copied. Bob will then end up with 92 chromosomes inside of it

[pic]

G2 The proteins are fixing themselves to form fibers known as spindle. The spindle fibers will be very useful during the chromosome movement ahead. The spindle fibers are formed at the beginning of this process and vanish by the end of it. These spindle fibers are formed of microtubules.
[pic]

Prophase
Visible threads are forming inside of Bob. At his point there are two copies of all of the chromosomes inside of Bob. Each chromosome is called a chromatid. The chromatids will join at the centromere inside of Bob. The chromatids will become visible in its pairs. The spindle fibers are beginning to form.

[pic]

Metaphase Pairs of chromatids are lining up on the equatorial plate inside of Bob. The equatorial plate is also known as the metaphase plate. The pairs are connected at the centromere where the spindle fibers where attached. Two chromatids become completely separate from one another.
[pic]

Anaphase Bob is feeling a lot of movement inside of him. The chromatids are

Cell Cycle: Life Cycle Of Cell Growth And Division

16.1 * Cell cycle: life cycle of a cell, continuous sequence of cell growth and division * Somatic cells: any of the cells of a multicellular organism except those that form gametes * Parent cell: original cell that divides to produce two new daughter cells during cell division (mitosis) * Daughter cell: any one of two cells produced from the division of a parent cell * DNA: deoxyribonucleic acid (DNA): double-stranded nucleic acid molecule that governs the processes of heredity…

Essay on Cell Cycle

The cell cycle is also known as cell division which is the continuity of life based on the reproduction of cells. The stages of the cell cycle include interphase (which is made up of three stages: G1, S & G2), mitosis and cytokinesis. The first stage of the cell cycle is interphase. Interphase consists of three stages: G1 (first gap), S (Synthesis), and G2 (second gap). During these three sub-phases, the cell grows by making proteins and organelles. But during the S phase is the only time when chromosomes…

The Effects Of The Cell Cycle

E. Coli Gowth INTRO In order for any cell to grow, it needs a source of nutrients; also known as energy. The process in which cells grow and multiply is known as the cell cycle. Once energy is attained within the cell, the cell wall inflates, and the cell begins to expand in size. Similarly, bacteria populations also go through phases of growth. There are four main stages of bacteria growth. (Earl 2014) The first phase is Lag Phase. Cell population remains virtually unchanged in this phase…

Lehew Cell Cycle And Cancer

Cell Cycle and Cancer By Samuel Lehew The cell cycle is a complex set of stages where the cell duplicates itself, in which the captivating process of this is explained cancer will also be explained and how the different types of cancer can be treated differently. The cell cycle has two main phases, Interphase and Mitosis. Interphase consists of three stages of the cell cycle, G1, S, and G2. All of these stages and checkpoints have to be very precise every time they are used or it can result in…

Cancer: Relation To Cell Cycle Checks

Cell Cycle Relation To Cell Cycle Checkpoints: Cancer is related to the cell cycle checkpoints because cells are passing through the checkpoints too fast and the result is cancer. What that means is that the checkpoint G1 is the point where the cell is decided to be able to divide. But when cancer is found, it is uncontrollable growth throughout cells in different areas of the body. So, the cell that is now cancer has passed by the G1 checkpoint without being checked to see if it has fully developed…

Cell Division Research Paper

living thing is made up of cells, they are the building blocks of organisms. There are trillions of cells within the human body that provide structure as well as carry out different functions. Each cell is shaped accordingly, dependent on the job that it is required to do. Within the cell are tiny organelles that aid in everyday cellular processes. These processes are imperative in enabling organisms to operate on the most basic level. One of the most vital functions of a cell is cellular division. It…
