Answer:
All these choices are correct
Explanation:
YACs stands for Yeast artificial chromosomes. These chromosomes are derived from a fungus species Saccharomyces cerevisiae. YACs are genetically modified and a 100—1000 kb fragments of DNA are inserted into a bacterial plasmid. The inserted DNA fragment can be cloned and physically mapped. In the presence of this fragment, the chromosome will be stable during extracellular replication and easily can be differentiated from colonies without the vector.
Answer:
The correct answer is statement B.
Explanation:
The enzymes may be present in the form of trimers, dimers, or tetramers. Various examples of trimers, dimers, and tetramer proteins are known, of them, the NEMO's diners are considered to be held by disulfide bonds. Thus, it can be hypothesized that the enzyme under examination is a multimer captivated by disulfide bonds, with each exhibiting catalytic sites.
On dissociation or reduction of disulfide bonds, the enzyme cleaves into its many single units. This illustrates the reduction in catalytic activity. Each active site in single unit will work, however, at a gradual rate. This also illustrates determination of multiple globular proteins after disulfide reduction.
The sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
Answer:
3,500-calorie rule
Explanation:
The burning of fat provides about 9 kcal/g of fat and one pound of weight equals 454 g, therefore, one pound of fat contains 4086 kcal.
However, the research on the burning of fat indicates that about 3500 kcal are burned as the fat contains only 87% of the lipid which is burned and therefore 87% of 454 will provide 3,500 kcal.
So according to the 3,500 kcal rule, if one pound of fat has to be burned in one week therefore 3500/7 kcal has to burn daily.
Thus, 500 kcal according to the 3,500 kcal rule will be burned.
The stroma is found in the chloroplast. it surrounds the grana, the grana is where photosynthesis takes place. The dependent that depends on light capture the energy,from the light,and then uses this to create ATP in the 2nd stage, then uses the product to reduce carbon.
