Can viruses and/or bacteria cause mutation(s) in human genes? If so, do stem cells correct the mutations after the viral/bacterial infection is gone?

Can viruses and/or bacteria cause mutation(s) in human genes?  If so, do stem cells correct the mutations after the viral/bacterial infection is gone?

Too complex: Cannot possibly begin to answer this question in the space of 400 characters. You need to discuss this face to face with somebody who specializes in the field. ...Read more

Dna (Definition)

Dna are the coding molecules found in all living things on earth which contain the instructions on how to build living things. Its is comprised the nucleotide molecules which are ...Read more

Can gene thereapy alter a living persons genome?

Can gene thereapy alter a living persons genome?

No: Not at this point yet. The aim of such therapy would be not to alter the human genome but rather to correct it to make it as closer o normal as possible. ...Read more

Can the HIV virus have originated from human experiments with chemical weapons.?

No: Hiv is a virus and humans could not have created it with chemicals. It likely spread from primates to humans. ...Read more

Pros of viral vectors in gene therapy?

They work!: For gene therapy to work, material must be transported into cells, such as new genes to insert , or proteins that cleave (break apart) chains or delete genes. Since viruses are capable of entering cells (that is how they infect them) and are able to integrate their own genes into the dna inside the cell, they can be effective in gene therapy. But the virus must be or be made harmless first. ...Read more

How do dna, mutation, genotype, phenotype, and natural selection interconnect to cause evolution?

How do dna, mutation, genotype, phenotype, and natural selection interconnect to cause evolution?

Modern synthesis: It's as well-established as anything in science, but would take more than 400 characters to explain. You owe it to yourself, as an educated person who must participate in community decision making, to understand it. There are a huge number of good books on the subject. Best wishes. ...Read more

Does HIV DNA PCR have different assays for the strains of hiv1 and hiv2?

Does HIV DNA PCR have different assays for the strains of hiv1 and hiv2?

Yes, but complicated: Trying to tell whether a person has HIV-1, HIV-2, or both, can get complicated. If a person has high risk exposures or has symptoms, he can see an HIV Infectious Disease doctor and trust the advice, but follow-up as instructed. There are many different tests (usually by various manufacturers) in different parts of the world, which happen to have different prevalences for various HIV strains. ...Read more

How is DNA mutated by carcinogens ?

How is DNA mutated by carcinogens ?

DNA breakdown: Carcinogens can cause cells to rapidly divide in response to the continual attack on their survival. With this high cell turnover coves oxidative/free radical damage (stealing of electrons) and in many case errors in dna sequencing resulted in a mutated dna stand. The body sees this imperfect dna strand as a foreign invader and eliminates it through the immune system. ...Read more

What is the human genome project and whose genome was sequenced?

What is the human genome project and whose genome was sequenced?

Map of Human DNA: The Human Genome Project created a map of human DNA and was completed in 2003. Anonymous samples were donated by several people, but the majority of the "genome map" is from a single male donor from Buffalo, NY. The identity of this individual is not known by researchers who sequenced the DNA. ...Read more

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

Cellular immunity: These are cells that work as part of the cellular immune system, fighting certain fungal (e.g. Cryptococcus), viral (e.g. Herpesviruses), parastic (e.g. Toxoplasma), and bacterial (e.g. Tuberulosis) infections. The cellular immune system also helps to prevent certain cancers, such as lymphomas. ...Read more

How could a made in canada version of malaria appear through DNA replication and the adaptability of microorganisms?

Is this a SCI FY: question. I don't understand what you are asking? Even if I did understand. there are so many people worried about actual diseases such as Ebola - I don't think I would want to get into the theoretical ?'s. ...Read more

Which viruses, bacteria, and/or fungi are causative factors in channelopathies [transient receptor potential (trp) channels, in particular]?

The cause if: These rare abnormalities are though to be genetic and/or autoimmune, not secondary to an infection, but you should discuss it with your diagnosing physician. ...Read more

Can you outline the cellular mechanism by which HIV infects humans?

Can you outline the cellular mechanism by which HIV infects humans?

HIV infection: Well this is something I can lecture about - although that will take up to an hour at least to do it any justice! You might want to read some general literature on the topic - then if you have specific Qs we can try to answer them here. Only allowed 400 characters here you see... Hope this helps. https://en.wikipedia.org/wiki/HIV ...Read more

Scientists test for alleles that cause human genetic disorders by what method?

Scientists test for alleles that cause human genetic disorders by what method?

Molecular Methods: Identifying alleles associated with disease can be done by numerous different methods depending on the type of genetic alteration. Gene sequencing is often the gold standard. However, for disease caused by deletion or insertion of a segment of DNA, a technique called Fluoresense In Situ Hybridization is used. For detection of single base pair changes numerous different techniques can be used ...Read more

Is GBS a second cause of my UTI? culture results: 10,000 CFU/mL Streptococcus Group B, (S. agalactiae) AND >100,000 CFU/mL Escherichia coli

Is GBS a second cause of my UTI? culture results:  10,000 CFU/mL Streptococcus Group B, (S. agalactiae)	AND >100,000 CFU/mL Escherichia coli

Contamination: Urinary tract infection is usually a single organism. GBS is a normal organism of the vagina. In your case, it is likely that e. coli is the responsible organism for your UTI and GBS is just a contaminant especially that the count is 10,000 ...Read more
