Which statement indicates that different parts of the genetic information are used in different kinds of cells, even in the same organism?
(1) the cells produced by a zygote usually have different genes.
(2) as an embryo develops, various tissues and organs are produced.
(3) replicated chromosomes separate during gamete formation.
(4) offspring have a combination of genes from both parents.

Explanation:

The genetic material (DNA) in organisms contains portions that hold the information needed for a cell's functioning. i.e. it directs all the living processes e.g reproduction, movement, excretion etc.

A cell carries all the DNA coding for the proteins needed by it. However, all these genes will not be expressed at once, some genes are turned on in some cells and off in others, instead cells continually divide and differentiate in the process. Cell differentiation is the act by which cells change their function or phenotypical type. This process occurs as a result of change in gene expression. For example, a developing embryo will produce various organs and tissues based on the differentiation of cells directed by the expression of certain information encoded by the genes on the genetic material (DNA).

Note that, all cells contain the same DNA but the expression of certain genes on it determines the types of cell that will be made.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
