Cell Continuity
Cell Continuity
Cell continuity is the ability of cells to divide and survive from one generation to the next.
3 steps to form a new cell
— Produce materials it will need
— Grows larger
— Reproduces to form a new cell
Ø When dividing = Chromatin forms a numbers of clearly distinguishable Chromosomes
Ø Chromosomes are in pairs in diploid cell, called homologous pairs.
Ø Homologous chromosomes are pairs of chromosomes that posses the same genes, in the same positions.
Ø Diploid is symbolised as ‘2n’ and total no. of chromosomes in cell is given as 2n=46 in humans
Ø In diploid cells, 1 chromosome from the homologous pair comes from the mother and the other comes from the father.
