Kesav will Planting nitrogen-fixing crops, such as peas, in rotation with wheat crops can dramatically reduce the variability of farmers' income with a high-yield, high-protein harvest. ... Instead, they depend on the presence of nitrogen as ammonium or nitrate ions in the soil.
Answer:
The tryptophan synthase enzyme catalyzes the synthesis of tryptophan. This enzyme is found in all kingdoms except animals.
Tryptophan synthase has a hydrophobic channel that facilitates the passage of an intermediate from one enzyme to the other during the biosynthesis of tryptophan, which makes faster the metabolic process.
Answer:
Maternal inheritance means the transfer of characters from mothers to offspring through mitochondria. The paternal leakage means some mitochondria transfer from the father as well.
As the information given in the question, the amount of DNA from father's mitochondria is small. The quite small amount of DNA will not affect the conclusions and results that are made by the studies and do not affect the inheritance of mitochondrial DNA.
Answer:
The correct answers are: Ribosome, Mitochondria, Chloroplast (in case of a plant cell).
Explanation:
- The Endo-membrane system in the cell represents the membranes of the Nucleus, Endoplasmic Reticulum, Golgi apparatus, Plasma Membrane, Vacuole and Lysosome.
- The Nuclear Envelope is made up of a phospholipid bilayer which remains in continuation with the ER (endoplasmic reticulum) membrane.
- Therefore, fluorescent tagged integral membrane protein localised in the outer nuclear envelope can move into the ER membrane by lateral movement or through vesicles that bud off from the membrane of the nuclear envelope and fuse with that of the ER membrane.
- Vesicles bud off from the membrane of the ER and fuse with the Golgi apparatus. Therefore, the fluorescent tagged integral membrane protein can move into the membrane of the Golgi apparatus.
- Vesicles bud off from the Golgi apparatus and fuse with the Plasma membrane, Lysosome membrane, and Vacuole membrane. Hence, the fluorescent tagged integral membrane protein can be found in all these organelles.
- Ribosome lacks a membrane and hence, the fluorescent tagged integral membrane protein will be absent over here.
- Both Mitochondria and Chloroplast, are self-replicating and dividing organelles. Their proteins (membrane or matrix) are encoded mostly by their own genome. Also, vesicles that bud from from nucleus or ER or Golgi apparatus do not fuse into their membrane. Hence, the fluorescent tagged protein would not be able to reach their membrane.
