2.5 Cell Division
2.5.3 State that interphase is an active period in the life of a cell when many metabolic reactions occur, including protein synthesis, DNA replication and an increase in the number of mitochondria and/or chloroplasts.
2.5.3 State that interphase is an active period in the life of a cell when many metabolic reactions occur, including protein synthesis, DNA replication and an increase in the number of mitochondria and/or chloroplasts (1).
State means to give a specific name, value or other brief answer without explanation or calculation.
-
The cell specialises to a particular function in a process called differentiation.
-
Through gene expression and protein synthesis there is a specialisation of cell structure and function.
-
During this interphase the cell carries out this specialist function.
-
The length of the interphase varies from one type of cell to another.
-
G1 follows cytokinesis. The cell is involved in the synthesis of various proteins which allow the cell to specialise.
-
S-phase involves the replication of DNA molecules which takes place prior to the phases of mitosis.
- G2 preparation for the phases of mitosis which involves the replication of mitochondria and in the case of plants, the chloroplast.
