Hm Well, Hematopoiesis is defined as the process of blood cell production, multiplication and specialization in the bone marrow.
Answer:
The correct answer is option 3. a nucleus.
Explanation:
The first genetic material present in the early organisms were RNA which was present in the microscopic organisms back then 3.5 billion years ago which means it is normal to have RNA in such microfossils chemical analysis.
Since, the nucleus was not present in early life forms of prokaryotes like bacteria. so, it is unusual to find nucleus in the fossils of stromatolite rocks.
Thus, option III is the correct answer.
The correct answer would be A. The number of neutrons present in Krypton-82 would be 46. The atomic number of an atom represents the number of protons present while the mass number is the sum of the neutrons and protons in the atom. The mass number for the given atom is 82. So, 82-36 = 46 neutrons present.
Ti plasmid encoded octopine and nopaline catabolism in Agrobac terium Ti plasmid-encoded genes required by the micro organism for opine catabolism.
The occ and noc areas in octopine and nopaline Ti plasmids, respectively, are accountable for the catabolism of octopine and nopaline in Agrobacterium. The functions are activated within the presence of the opines with the aid of OccR and NocR, related regulatory proteins, and the promoters incorporate commonplace collection motifs.
we have investigated Ti plasmid in heterologous interactions among the regulators and the promoters. previous experiments the usage of all possible heterologous combos of opines, regulators, and promoters in vivo had demonstrated that handiest the aggregate of nopalme, NocR, and the occ promoter led to restricted promoter activation. We now display that OccR and NocR bind to the heterologous promoters in vitro and in vivo.
The weak or non-existent promoter activation truly located can be explained by the idea that OccR and NocR use distinct activation mechanisms; we investigated protein-brought about DNA bending due to reports that the two regulators vary in this respect.
