Which of the following not an enzyme mediated process
1) G1
and G2
phases of meiosis
2) S-phase of mitosis
3) Pachytene of meiosis-I
4) None of the above

4) None of the above

Explanation:

Enzymes are known for mediating biological or chemical processes.

Meiosis and mitosis both are part of a biological process called cell cycle or cell division.

The cell cycle is mediated by enzyme cyclins and cyclin-dependent kinases (CDK). cyclin-CDK in G1 phase helps to prepare the cell for S phase. cyclin-CDK also drives Pachytene of meiosis-I

During S-phase of mitosis, ubiquitin ligase helps in mitotic spindle assembly.

Hence, the correct answer is "4) None of the above"

is this a psat question, if so do not cheat try your best.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
