S. viridans is not a species. All spreptococci irrespective of haemolysis type have been currently divided into seven genetically distinct groups: pyogenic streptococci (S. pyogenes, S.agalactiae, S. dysgalactiae) - group I; Str. bovis group (II); Str. mitis group (S. mitis, S. pneumoniae, S. orali...

Re: difference between over-expression and a genomic rescue

... into cells or by introducing exogenously-transcribed mRNA into cells. This is a common technique in embryo studies, where (at least for zebrafsih, Xenopus, sea urchins and Ciona) the plasmid or mRNA us generally microinjected into the early zygote though a thin glass needle so that after mitosis ...

Re: Can a gene be situated at multiple loci in a genome?

Yes, there are such genes, like for rRNA are many copies in tandem (e.g. in human about 200 copies, in Xenopus even 600 copies) and also for histones, I think. But also, there are sometimes genes duplicated by chromosome rearragnment. In that case, whole part of chromosome ...

Frog Egg Physilogy

... just put them in distilled water and the put them in the PCR reaction. Anyway, i think that you would have better chance looking up a protocol for Xenopus laevis, people have been studying the eggs of that organism for decades. Then try that and see if it works

Re: IBO 2003 questions- please help me out

... proteins that were, as best as I could find, equally distant from a human protein. Here’s what I found.: Histone H1 (Human) is 72% identical to Xenopus (frog) H1 and 54% identical to Sea Urchin H1 DNA Polymerase A (Human) is 67% identical to Xenopus Polym A and 37% identical to Arabadopsis (a ...
