Question

why does the information in dna have to be copied onto rna?dna is unable to leave the nucleusdna doesnt contain uracilthere are three different types of rnarna contains ribose sugar

Explanation:

DNA is located in the nucleus. Proteins are synthesized in the cytoplasm. DNA cannot leave the nucleus. RNA, which can move out of the nucleus, carries the genetic information from DNA to the ribosomes in the cytoplasm for protein synthesis. The other options (DNA not containing uracil, three types of RNA, RNA having ribose sugar) are facts about DNA and RNA but do not explain why DNA information is copied to RNA for the purpose of protein synthesis (the main reason for the copying).

Answer:

DNA is unable to leave the nucleus.
