If every cell in the body gets the same DNA, how do the cells of an embryo make different structures and take on different roles

The options are not given, here are the options.

A. Different transcription factors are active in different cells

B. Different transcription factors are encoded in the DNA.

C. Genes are spliced differently in different cells.

D. Translation is regulated so that different cells may make more of certain proteins.

E. Some cells lack ribosomes while others use them.

F. cells delete a set of unused genes from their chromosomes.

The correct options are;

A. Different transcription factors are active in different cells

C. Genes are spliced differently in different cells.

D. Translation is regulated so that different cells may make more of certain proteins.

Explanation:

Every cell in the body have the same DNA but different function because a single cell in the body divides many times into several cells and these cells have the same DNA , DNA is the genetic information needed to make a person and it is stored in over 20,000 human genes found in almost all the cells in the body.

For the gene to be expressed into information, it must be made into protein and the protein goes out and perform some specific functions.

And for a cell to work, alot of proteins must be made to perform different functions.

Different transcription factors are active in different cells which make cells to perform different roles and functions.

Genes are spliced differently in different cells to make different proteins performing different task.
