i got a tetanus shot yesterday, even though i’d had one a few years ago because there was another vaccine in it. My dr said that because i’m going to be working with children that I needed to be vacinated for it this time. btw it was only one needle with tetanus and something else in it. what was it?

How many genes are there in just one human chromosome?
Genes are supposed to be in pairs, yes? And chromosomes too? One gene in one chromosome and the other in its homolog?
No no no no…
NOT how much chromosomes in a human cell!
How much GENES in a chromosome!

The Vivotif Berna Typhoid Vaccine Live Oral Ty21a is supposed to be refrigerated [2ºC - 8ºC (35.6ºF - 46.4ºF)] "at all times" between doses, according to the instructions. Does anyone know if it possible for the live vaccine to survive 25 minutes out of refrigeration?

I’ve always been vaccinated, no problems to report.
Why are so many opposed to the current vaccine(s)?
Supposedly there is some potentially ‘iffy’ stuff in it, but is that at all unusual for a vaccine?

I heard that the gene that leads to red hair also affects skin color?
Why is it not as simple as eye color genes?

I just received a vaccine for yellow fever with a live virus today. If yellow fever can be spread by a mosquito and the means of transmission is basically needle like. What makes the vaccine any different from a mosquito bite?

Genes important in the embryonic development of animals, such as homeobox-containing genes, have been relatively well conserved during evolution; that is, they are more similar among different species than are many other genes. Why do you think this is.

Or are they semi synthetic because they are modified after they are isolated from bacteria? I was curious because the plasmid used in genetic engineering was like "perfect" in the sense it has "complete" set of genes: resistance, polylinker etc…Does "natural" plasmid has this?Because many dont use natural plasmid in the lab if i am not mistaken????
Ok………………………….
U mean the plasmid was synthesis from origins from bacteria used as precursor?Why cant the origin be synthesized too?

Ok i am going into 10 grade and my lil bro is going into 7th, he got a papaer home saying he needed to get hep A &B vaccine before entering 7 th grade,though he hasnt gotten them yet and school starts in 3 weeks, what will happen to him?
