How does DNA send it's instructions to the other parts of the cell?

Tatiana [17]

Answer:Through mRNA, the DNA is able to transmit its messages out to other parts of the cell. (Learn more about mRNA here.) Information from the DNA is coded into mRNA which leaves the nucleus of the cell DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies (the white region) and is used by ribosomes (outlined in green). hope this helps have a great night ❤️❤️❤️
