- Plasmid
- Cosmid
- Lambda phage
- Yeast artificial chromosomes
- Which one of the following statements about meiosis in plants is NOT correct?
- The cytomictic channels in the medicates of higher plants permit passage of a number of cytoplasm components from on cell to the other to maintain the meiotic synchrony
- There is a conspicuous reappearance of a large proportion of ribosome population during zymogene in the meiocyte
