1. Cells must be provided with food, oxygen and basically nutrients in order to survive and function properly. However, when cells get bigger, required materials passing through the cell membrane are not enough to feed the inside organnelles and materials. Therefore, the cell divides so that its contents can be supplied with nutrients in an optimum ratio. Moreover, we know that the cells are the smallest living unit of life. Thus, they divide in order to reproduce just like every other living thing.

Where DNA contains genetic material, RNA copies the material and helps to synthesize it into protein. Also, DNA has deoxyribose sugar and RNA has ribose sugar. 2) Name and discuss at least three things RNA do in the cell, based on what you learned in the video and the tutorials. RNA makes protein and acts as a carrier of information. There are 3 types of RNA which perform

The cell membrane regulates the deoxyribonucleic acid, enzymes, and it builds a pathways for any reaction such as metabolic. When waste products are present the cell membrane gets rid of it and the cell membrane allows important things inside . A great example of what the cell membrane allows in or out is water and oxygen. Specific molecules are only made to enter the cell which is also called semipermeable. Molecules can be passed by active transport or either passive transport.

Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.

The idea of cell division, mitosis and binary fission, are ideas that make me stop and think. Mitosis is a type of cell division that happens in cells with a nucleus, and ends in two identical daughter cells. Mitosis interests me because of how complex the process is. It is amazing how it goes through various stages without hardly ever a mistake, and ends with two identical daughter cells. Binary Fission is a type of cell division that happens in cells without a nucleus, and also ends with two identical cells.

DNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems.
