What else can I help you with?
If a cell did not have ribosomes it would be unable to?
synthesize protein, it will not be able to manufactur the proteins which is fundamental for the cells wore work effctively and produce atp energy
What part of the human body can a ribosomes be compared to?
They create proteins, which is important, because without proteins we would not be able to function.
Why is it necessary for bacteria to be able to withstand fluctuations in temperature within the human body?
A bacterium's cell membrane allows it to withstand fluctuations in temperature within the human body. This is necessary in order for the bacterium to survive in that environment.
Under what conditions will bacteria thrive?
Bacteria typically thrive in warm, humid, and dark environments. This is a reason why the human body is an ideal breeding-ground for bacteria; the interior is the ideal temperature for bacteria, well-supplied with adequate moisture and nutrition, and usually dark. Additionally, some bacteria, extremophiles, are able to survive, even thrive, in extremely acidic, alkaline, or salty environments, or incredibly hot or cold environments, or incredibly wet or dry environments.
What is thermophilic bacteria?
The thermoduric bacteria refers to the bacteria that can survive to varying extent. This type of bacteria is able to survive the pasteurization process.
What about some bacteria is important to human in term of our being able to make proteins and nucleic acid from the food we eat?
they can fix nitrogen
Why bacteria need proteins?
Not only bacteria, also fungi, algae, plants, animals and human need proteins. Bacteria do carry out metabolic process, reproduction, motility and other life processes, hence they need proteins. In case of human, not all the amino acids can be synthesized by our cell, so we consume protein diet to acquire them.
Which type of DNA technology is used to cause bacteria to produce human insulin?
The type of DNA technology used to cause bacteria to produce human insulin is recombinant DNA technology. In this process, the gene for human insulin is inserted into the genome of a bacterium, such as Escherichia coli (E. coli), using techniques such as restriction enzymes and ligase enzymes. Once the gene is inserted, the bacterium is then able to produce human insulin, which can be purified and used for medical purposes. This technology has revolutionized the production of insulin, making it more accessible and affordable for people with diabetes. Recombinant DNA technology has also been used to produce many other human proteins, such as growth hormone and blood clotting factors, with great success.
Why do transgenic bacteria that have the gene for human insulin produce insulin in great abundance?
It is the easiest way for this protein to be produced. The DNA encoding human insulin can be put under the control of a constituitively active promoter and transfected into bacteria, which then produce the protein with their cellular machinery.
How can genetic technology allow us to create human insulin using bacteria?
We are able to "splice" genes from one organism into the DNA of another to give it traits we want. In this case, we put the gene for insulin into the DNA of a bacterium, which causes it to produce insulin, which we can use.
How would you describe a bacteria that is pathogenic?
A pathogenic bacteria is capable of causing disease in its host organism by invading tissues and compromising the host's immune response. It can produce toxins or release harmful enzymes that contribute to the development of illness or infection.
Why can bacteria express human genes?
It is my understanding that often eukariotic (multicellular organisms like humans) genes do not "work"(that is, cannot be translated) in prokariotes(bacteria) because bacteria are very very simple compaired to eukaria. Eukaria have complecated structures and mechanisms for the transcription and translation of DNA, bacteria only have plasmids and ribosomes. However, we have been able to get bacteria to use some human genes, most notably the gene to make insulin. Because eukariotic DNA has introns(random, useless segments of DNA) that are removed by special machinery before it is transcribed, scientists must remove all of the introns before inserting the DNA into the bacteria. They do this by obtaining mRNA from a human before it is transcribed in the ribosome, and using the enzyme reverse transcriptase(an enzyme in retroviruses such as HIV) to reverse transcribe the mRNA into cDNA("complementary" DNA that does not contain introns). cDNA can be spliced into a bacterium, and we can often make the genes "work" in bacteria. To answer the question, the genetic code is the same in every organism, so we can make human genes work in bacteria.
What about some bacteria is important to humans in terms of our being able to make proteins and nucleic acids from the foods we eat?
Some bacteria help break down food in our digestive system, making it easier for our bodies to absorb the nutrients needed to make proteins and nucleic acids. Additionally, certain bacteria in our gut produce vitamins and enzymes that aid in the digestion and absorption of essential nutrients. This symbiotic relationship between humans and bacteria is crucial for maintaining a healthy balance in our body.
Why are some bacteria able to grow on count agar that contains milk even though they do not produce any proteases?
Some bacteria are able to utilize the nutrients in milk other than just proteins. For example, they can use lactose as a carbon source. Additionally, some bacteria may be able to break down the milk into simpler compounds through non-protease mechanisms to support their growth on count agar.
If a cell lacked ribosomes it wouldn't be able to do what?
If a cell lacked ribosomes, it wouldn't be able to carry out protein synthesis. Ribosomes are responsible for translating mRNA into proteins, so without ribosomes, the cell would not be able to produce the necessary proteins for its functions.
A mutant strain of bacteria that has no ribosomes is incapable of what?
It would be incapable of protein synthesis. The ribosomes are responsible for the assembly of amino acid molecules, to form a proteins that are determined by the nucleotide sequence of the mRNA molecules.
Kingdom able to produce their own food?
Plants, some protists and some bacteria can produce their own food through photosynthesis.
