1.	Which of the following species has natural competence?(a) Saccharomyces cerevisiae(b) Staphylococcus Aeruginosa(c) Gelidium corneum(d) Streptococcus pneumoniaeThe question was posed to me in an interview for internship.This key question is from Gene Mapping in Bacteria by Transformation topic in section Genomics : The Mapping and Sequencing of Genomes of Cytogenetics
Answer» Right choice is (d) Streptococcus pneumoniae Easy EXPLANATION: Only 1% of all the bacterial STRAINS are naturally competent. One among these is Streptococcus pneumonia, which can TAKE up the chromosomes from the MEDIUM without prior treatment.
