What else can I help you with?
Can you get DNA off of brick?
The brick itself doesn't have any DNA but there undoubtably are bacteria and other microbes on it that do have DNA.
What organism doe not contain DNA?
None! If Any Did NOT Then They Would Be Completely Untraceable Even To Human And Technology Standards.
Even though the bacteria don't have any DNA but they can do replication process how can it possible?
Bacteria do have DNA. Bacteria are prokaryotic cells, meaning they are fully functional cells (have DNA, RNA, ribosomes, cytoplasm). They just do not have a nucleus to house their like eukaryotic cells.
Is there any different between human biology and microbiology?
Microbiology is dealing with the biology of microbes and small organisms, such as bacteria. Human biology is a completely different field - it deals with the study of humans on all different levels (molecular upwards).
What can the researcher conclude about the bacteria that grow on the nutrient medium?
The researcher can conclude the type of bacteria present based on the appearance of colonies and any biochemical tests performed. They can infer the growth requirements and potential pathogenicity of the bacteria from the growth patterns observed. Further analysis such as DNA sequencing may be needed for accurate identification.
How do bacteria protect?
To protect themselves, many types of bacteria have developed a method to chop up any foreign DNA, like an attacking phage. They do this by creating an endonuclease, which is an enzyme that cuts DNA.
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 bacteria invades the human body?
There are any number of bacteria that invade the human body. Some of these include E. coli, Neisseria Meningitides and Mycobacterium tuberculosis.
Is it safe to consume food products that contain human DNA?
Yes, it is generally safe to consume food products that contain human DNA. The human DNA in food products is broken down during digestion and does not pose any health risks.
Are there any bacteria on or in the human body if so where?
Yes. On the skin and In the Intestines.
Is there any used for bacteria?
yes. for example, there are bacteria in the human intestinal tract that synthesize Vitamin K for us.
Is daffodil DNA in human makeup?
There are two different answers to this question:Please remember that daffodils are in the plant kingdom and humans are in the animal kingdom. They are very different in their genetic makeups. You will not find any daffodil DNA in a human genome. Humans just don't have the enzymes to handle plant cell byproducts.There is an fragrant oil which can be made from different varieties of daffodil. They contribute to the ingedients of perfume formulations. It is not the DNA of a daffodil, but the byproduct of the daffodil's DNA that is used in perfumes. There is also a yellow dye that can be produced from daffodils and might be used in eye makeup.
