How is Mycoplasma a gram positive bacteria

Despite the lack of a cell wall, many taxonomists have classified Mycoplasma and relatives in the phylum Firmicutes, consisting of low G+C Gram-positive bacteria such as Clostridium, Lactobacillus, and Streptococcus based on 16S rRNA gene analysis.

Graphs depicting qPCR fold change

... it is harder to appreciate the extent of down-regulation. 2. Using inverse values where negative values (<-1) represent down-regulation and positive values (>+1) represent up-regulation. However, the problem with this approach is that a fold change of +1 is essentially equal to -1, and ...

Help: Confused with primers in a PCR of a vector?

... I'm not entirely familiar with what is going on. We recently ligated a gene into a pBS vector and popped it into some E. coli cells. We looked for positive clones via blue/white screening and isolated/purified the respective plasmid. Then, we carried out a PCR reaction of the pBS-gene (our clone). ...
