Answer:
No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.
Explanation
telomerase is not responsible for causing deregulation while oncogenes cause deregulation .
Telomeres length shorten after the cell division which stops them to divide again and cell die.
Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could prevent senescence.
The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.
Answer:
The maintainance of the lytic and the lysogenic cycle is done by the Cro and the lambda repressor proteins when the number of bacteria is higher than the number of viruses that is the mode of infectivity or MOI the virus under goes the lytic cycle. This is done by the cleaving of the proteins.
So high nutrient concentration in the gut promotes the growth of the E coli that forms a protease that cleaves the Cro protein and causes the activation of the lysis in the bacteria. So in the high nutrient concentration the bacteria is itself responsible for its lysis.
Many act as decomposers, breaking down the dead bodies of plants and animals and recycling the nutrients they hold. ... The fungal decay makes these nutrients and carbon dioxide available to green plants for photosynthesis, and it completes an important cycle of raw materials in the ecosystem.
Answer: Explain why two different enzymes are needed for the synthesis of glycogen from glucose phosphate. This is because enzymes are substrate specific, in that each enzyme only catalyzes one substrate. This is because enzyme activity increases with concentration, or availability of the substrates.
