Determination of allele frequencies in nine short tandem repeat loci of five human sub-populations in Botswana
Mpoloka, S.W.; Kgotlele, T.; Wally, A. (Academic Journals, www.academicjournals.org, 2008-04-17)Allele frequencies for nine short tandem repeat (STR) loci from the AmpFlSTR® Profiler Plus PCR Amplification Kit were determined in five subpopulations across Botswana and tested for suitability for use in individual ... -
Effects of prolonged UV-B exposure in plants
Mpoloka, S.W. (Academic Journals. http://www.academicjournals.org/AJB, 2008)Over the past few decades, there has been a depletion of the stratospheric ozone layer due to emissions of halogen-containing compounds of anthropogenic origin. This has resulted in a concomitant increase in solar ... -
Investigating evidence for UV-B induced mutagenesis in dimorphotheca sinuata using the 18S rDNA and rbcL gene sequences
Mpoloka, S.W. (American-Eurasian Network for Scientific Information. http://www.aensi.org/aeb_online.html, 2008)The nuclear 18S rDNA and chloroplast encoded rbcL gene sequences were used to investigate the evidence of residual UV-B induced mutagenesis in Dimorphotheca sinuata plants. The probes were generated by the polymerase chain ... -
Multivariate analysis of Harpagophytum DC. ex Meisn (Pedaliaceae) based on fruit characters
Muzila, M.; Setshogo, M.P.; Mpoloka, S.W. (Academic Journals; http://www.academicjournals.org/ijbc, 2011)Harpagophytum is bitypic and native to Southern Africa. Its two species are Harpagophytum procumbens and H. zeyheri. H. procumbens is medicinal. A reliable method of identifying the species is through its fruit. However, ... -
Potential effects of prolonged ultraviolet radiation exposure in plants: chloroplast DNA analysis
Mpoloka, S.W.; Abratt, V.A.; Mundree, S.G.; Thomson, J.A.; Musil, C.F. (IDOSI Publications, http://idosi.org/, 2007)The present study on the Namaqualand daisy, Dimorphotheca sinuata sought to address two main questions: - first whether the natural populations show any evidence of variation in the chloroplast genome, and secondly if the ... -
Residual effects of prolonged UV-B exposure on photosynthetic gene expression
Mpoloka, S.W. (Academic Journals, www.academicjournals.org, 2010-08-18)Residual long-term effects of increased UV-B radiation were investigated in an indigenous plant species, Dimorphotheca sinuata, by analysing photosynthetic gene expression. Reductions were observed in the amount of the ... -
Screening for genetically modified organisms sequences in food samples in Botswana using the Biosmart Allin 2.0 GMO screening system
Mpoloka, S.W.; El-Kindiy, Oumi Kulthum (Botswana Journal of Technology, http://journals.ub.bw/index.php/bjt, 2017-04)We used the Allin 2.0 GMO screening system from Biosmart, Switzerland to screen for the presence of genetically modified food sequences in maize meal samples, fresh fruit and vegetables from some retailers around Gaborone, ...
