DNA Is Housed Within the Nucleus, but the MRNA Code

question 29

Multiple Choice

DNA is housed within the nucleus, but the mRNA code needs to leave in order to be translated into a protein. How does the mRNA code leave the nucleus if the nucleus is surrounded by the nuclear envelope?

• A) The nuclear envelope dissolves in order to allow the mRNA code to leave.
• B) The nuclear envelope contains pores that allow the mRNA to exit through.
• C) A vesicle will bud off from the nuclear envelope containing the mRNA.
• D) The mRNA will be coded into a protein within the nucleus. Then the protein leaves the nucleus.
