Safety of Splenda (Sucralose)

Hello! I'm looking for an answer that is based in factual evidence ... in reference to the safety of using Splenda as an artificial sweetener. I have done a pubmed search and found .... NOTHING that showed any adverse effects of this sweetner (that were statistically significant). Does anyone know o...

... and even if the sperm were able to break the egg wall (which it wouldn't be)... the different chromosome complement would be incompatible with life... and it would be very unlikely that a zygote would develop

This type of zygote would divide up to a certain point... but die very early on. It is likely that genetic imprinting may be the initial culprit... Where certain maternally and paternally genes are differentially expressed. (Ex. Mom expresses one gene, while dads copy of that gene is methylated and ...

So I realized that I didn't address your particular points: "we don’t have like a 2 headed bird of some weird spices that is like human but look a bit different like 6 fingers or toes I’m sure people with 6 or 3 fingers can all so survive as good as 5 fingers." A bird having 2 heads would ...

Yeah, i'm don't exactly wan to get into a evolution conversation ... But scientifically, there is more evidence that evolution is 'real'.. than any other 'theory'. So, lets look at it in very general terms... The reasoning behind why I say 46 chromosomesis "evolutionarily selected" is simp...

Evolution has selected for the number of chromosomes that a "normal, Healthy" person (organism) has. So gain of chromosomes or loss of chromosomes are detrimental .... (because each chromosome has MANY MANY genes)

change the regulation region... to a promoter sequence that is only active in (unique-to) small animals, plants or insects ...

not sure if there is a simpler solution?

There are 2 copies of chromosome 1 (One is maternally derived, the other is paternally derived) There are 2 copies of chromosome 2 (One is maternally derived, the other is paternally derived) There are 2 copies of chromosome 3 (One is maternally derived, the other is paternally derived) There are 2 ...

Re: Karyotype question

ok, so i am working on the lab for school, and all the chromosome pairs are there except for number 21, so there are 44 chromosomes and it is a male.. so if there is no chromosome 21 what does that mean? is there a disorder for this person-- if u could help that'd be great thanx- sara Monosomy 21 i...

Setup a gradient and try for a temperature that allows you to have the best of both worlds. I'm working with primers designed for 63 degrees but I'm annealing them at 55 and they're working quite nicely. ... there once was a time that I paid attention to Tm ... but I do soo much PCR nowadays, that ...

Thanks guys! I wrote a paper about a paper dealing with adar dependant miRNA editing... that showed that it happens, and can therefore target another set of mRNA or abolish miRNA targeting ability Anways... i was having some second thoughts after I wrote 5 pages on the topic. But, I got an A on the ...
