Question

what does DNA molecule contain?Name the functional segment of DNA. In which form is the DNA present in a cell when the cell is not dividing?

Answer 1

Answer:

DNA is made up of molecules called nucleotide . Each nucleotide contain phosphate group, a sugar group and a nitrogen base. The four type of nitrogen base are adenine(A) thymine (T) guanine ( G ) and cytosine ( C ) . The oder of these base is what determines DNA' s instructions , or genetic code.

The functional segment of DNA is genes.

DNA is present in both dividing and non dividing cells. In non dividing cell, the chromatin threads contain DNA which later condense to form chromosomes during dividing phase . DNA is a genetic material present in all cells.
