Dna (Overview)

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 paired in specific ways.

What is the implication of elevated single strand dna?

What is the implication of elevated single strand dna?

Auto-Immune Disorder: I think what you are asking is "elevation of anti-bodies to single strand dna". This means that you body is producing antibodies to specifically target proteins found throughout your body. This is process scene in some common rheumatologic disorders. I would suggest that since you are on Plaquenil (hydroxychloroquine) you physician is already aware of this or at least had the correct suspicion. ...Read more

How close could someone DNA who isn't related? Could everything match but 2 things?

How close could someone DNA who isn't related? Could everything match but 2 things?

It's complicated...: Dna tests don't compare every gene-pair in one person with those in another person. Instead, there are many types of tests. The tests look at only some sections of people's dna. One can ask the person doing the test which kind of test it is and how likely it is for various matches to occur. Lots of information is at: http://en. Wikipedia. Org/wiki/dna_profiling. ...Read more

Is there a way to have your DNA altered so you have 0% chance of having a child with downs?

Is there a way to have your DNA altered so you have 0% chance of having a child with downs?

Not a chance: At any age all pregnancies have about 4% risk of an unexpected outcome. (Premi, cleft palate, infection, DS, etc) As you pass 40 you begin to add higher risk of DS, as lifelong exposures to toxins affects egg quality. You can get non-invasive (mother's blood) information on a pregnancy as early as 8-10 wks with NIPP. This test commonly done for paternity can also detect DS very early. ...Read more

How safe is it to get a DNA on a baby before its born? And how far along do you need to be? How is it done?

Fetal DNA -: Hello! Firstly, fetal DNA comes from fetal cord sample, done after 16 wks AND before 21 weeks under u/sound. Its risky, significant risk of miscarriage, but if you are looking for significant disease AND are prepared to abort the pregnancy if you find it, then its invaluable. I would NOT advise it if you are not prepared to have an abortion if the fetus proved +ve for the disease you are seek. THX ...Read more

The double strand break in DNA used in Crispr tecnique, is this alteration then passed on to the offspring and future generations.?!

The double strand break in DNA used in Crispr tecnique, is this alteration then passed on to the offspring and future generations.?!

Depends: If it is done in germ line tissue -I.e. Eggs or sperm cells - then those changes are passed to future progeny. If the cells that have been altered are not in the germ line then they only affect that individual. ...Read more

How to check the DNA of a fetus?

How to check the DNA of a fetus?

Fetal DNA testing: DNA test during pregnancy must be performed by obtaining either a small sample of the placenta (i.e, chorionic villus sampling), or a sample of amniotic fluid that bathes the baby (i.e, amniocentesis). These fetal samples must be collected by the mother's obstetrician, and their collections pose a slight risk to both the mother and the fetus. ...Read more

Can chemo change your DNA profile?

Can chemo change your DNA profile?

Theoretically.....: It first depends on what what you were sampling to determine the profile (blood versus cheek cells vs semen). Dna profiling examines extremely polymorphic (varying) regions of the genome. If the chemo caused a dna change in a primitive stem cell in your body in one of these locations, it theoretically could affect a dna profile. Fun thought experiment, but super unlikely. ...Read more

How are instructions encoded in dna?

How are instructions encoded in dna?

Nucleotide sequence: Dna is a long chain of 4 molecules called nucleotides. The sequence of three in a row, codes for Amino Acids used to build enzymes and body parts. Other sequences turn the code on and off for certain segments. All of the codes are still not known and some information is transfered in other ways. All in all it is a remarkable bit of biology. ...Read more

Can I get my baby's DNA tested in utero?

Can I get my baby's DNA tested in utero?

Yes, but: Dna testing can be done on the fetus in utero, but the tests have risks. Chorionic villus sampling or amniocentesis involve needles inserted to gain samples. The process has the risk of triggering a miscarriage, infection or worse to mom and baby. There are medical reasons for these procedures under specific circumstances & these can be discussed with the ob. ...Read more
