A human cell contains approximately 3 billion base pairs and E. coli approximately 4.5 million base pairs.
Both bacteria and human cells are made up of a cell membrane, cytoplasm, and genetic material, but bacteria lack membrane-bound organelles like the nucleus found in human cells. Bacteria have a simpler structure and are typically smaller in size compared to human cells. Additionally, human cells are eukaryotic, while bacteria are prokaryotic.
No, bacteria cells are prokaryotic cells, meaning they do not have a nucleus or membrane-bound organelles, while human skin cells are eukaryotic cells with a nucleus and organelles. Additionally, bacteria cells are much smaller in size compared to human skin cells.
There are trillions of good bacteria present in the human body.
Antibiotics work by targeting specific structures or processes in bacteria that are essential for their survival, such as cell wall formation or protein synthesis. These structures or processes are not present in human cells, so the antibiotics are able to selectively kill the bacteria without harming human cells.
Bacteria are generally smaller in size compared to human cells. The average size of a bacterium is around 1-5 micrometers (µm), while the average size of a human cell can range from 10-30 micrometers.
Human cheek cells have a faster rate of division compared to normal cells because they are constantly being exposed to friction and wear, leading to a higher turnover rate. Additionally, cheek cells are part of the epithelial tissue, which typically undergoes frequent and rapid cell division for quick repair and regeneration.
Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.
One key genetic difference is the presence of a nucleus in human cells, which bacteria lack. Human cells have linear chromosomes enclosed within the nucleus, while bacteria have a single circular chromosome located in the cytoplasm. Additionally, bacteria may have plasmids, small circular DNA molecules that are often absent in human cells.
Penicillin targets the cell walls of bacteria, which are different from human cells. Human cells do not have cell walls like bacteria do, so penicillin does not harm them. This allows penicillin to selectively target bacterial cells while leaving human cells unharmed.
Predominantly multicellular not in bacteria but in human body • Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body • DNA occurs in a circular form in bacteria only
According to Wikipedia, only 1013 cells in the human body are human cells. The rest, out of 1014, are bacteria. This gives a total of around 9 x 1013 or 90 trillion bacteria.
There are thousands of chemicals that can kill human cells. Chemicals such as pesticides, bacteria cells, microbes, and also ammonia.
