Thermococcus, Methanococcus and Methanobacterium are groups of
1 bacteria containing a cytoskeleton and all membrane bound organelles
2 archaebacteria with peptidoglycan in their cell wall
3 archaebacteria that consists of protein homologous to eukaryotic core histones
4 most advanced type of bacteria
Explanation:
Thermococcus, Methanococcus and Methanobacterium are examples of Archaebacteria, which lack the histone protein found in eukaryotes. - Histones are of the same type and eukaryotic are similar to the archaeal ancestor of the histone family. Thermococcus, Methanococcus and Methanobacterium, whose histones are shorter than eukaryotic histones and assembled into tetramers.

Which one of the following does not differ in E.coli and Chlamydomonas?
1 Cell wall
2 Cell membrane
3 Ribosomes
4 Chromosomal Organization
Explanation:
E. coli (bacteria) is a prokaryote while Chlamydomonas (algae) is a eukaryote. It is the cell membrane which has similar organization in both the group. - Cell wall organization also differs as bacterial cell wall is rich in muramic acid while algae cell wall is rich in cellulosic.

Modern farmer's can increase the yield of paddy upto $50 \%$ by the use of :
1 Cyanobacteria
2 Rhizobium
3 Cyanobacteria in Azolla pinnata
4 Farm yard manure
Explanation:
The leaves of this species contain the Anabaena, Azolla, which is a symbiont that fixes nitrogen from the atmosphere, that the former can use this to give it is the ability to grow in habitats that are low in nitrogen. - Farmers keeps their plant in paddy because it generate valuable nitrogen via its symbiotic Cyanobacteria

Transduction in bacteria carried out by :
1 Bacteriophage
2 B.G.A.
3 Mycoplasma
4 Rickettssiae
Explanation:
Transduction is a mode of genetic transfer from one bacteria to another through a virus. - There is no direct contact between the bacterial cells. - In this process, bactoriophages, which infect bacteria, use host cells to multiplicate and while assembling they sometimes pack the bacterial DNA with them.
