Because its being viewed by a different angle. nothing looks the same a different angles but something highly symmetric. in this case a cell is definitely not symmetric
Answer:
False
Explanation:
Stem cells are different type of cells in human body that can develop into different other body cells like muscles cells or brain cells and they gave the capability to renew themselves through mitotic cell division.
Stem cells are not lost in childhood but can be use to treat diseases or infection, it can be use to grow new cells and replace damaged body cells.
Answer:
Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.
Explanation:
The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
Answer:
If you are referring to a cellular organelle than I would say lysosomes because, they do just that, they digest intracellular waste.
Answer:
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA
