Fofino [41]

Answer:

<h2>Interphase : divided into three phases, i) G1 phase, ii) S phase and iii) G2 phase.</h2><h2>Mitotic phase: i) prophase, ii) metaphase, iii) anaphase and v) telophase.</h2>

Explanation:

interphase : divided into three phases, i) G1 phase, ii) S phase and iii) G2 phase.

G1 phase: cell decide whether to divide or not and prepare itself for replication of DNA and arrange replication machinery.  otherwise it goes to G 0 phase.

S phase: DNA replication occurs in this phase.

G2 phase: cell duplicates all their contents and prepares for mitotic phase.

Mitotic phase:

i) prophase- chromosome condensation occurs,

ii) metaphase - chromosome arranges in meta-plate and spindle binds to each chromosomes  at centromere.

iii) anaphase- chromosome separates from sister chromatids.

iv) telophase- chromosome moves to each ends and formation of nuclear membrane begins.

cytokinesis:  there is division of cytoplasm and forming two daughter cells.

Answer:  

Uncompetitive inhibitor.

Explanation:  

Enzymes are the biological catalysts that catalyze the biological process and metabolic activity of the body. Without enzymes, all the biological activity becomes very slow. Enzyme provides suitable speed for the biological process. All enzymes are made up of protein. The uncompetitive inhibitor is the type of enzyme that only disturbs or affects multi-substrate enzymes and joins to enzymes only after one substrate has bound.

In meiosis 1 what happens during anaphase?
icang [17]

Anaphase I begins when the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle. Notice that in anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.
