Answer 2

Hello. You forgot to add the model needed to answer a question. The model is attached below:

Answer:

Noncoding sequences are removed from a newly synthesized RNA molecule

Explanation:

Step 2 of the process shown in the figure below refers to the formation of the pre-mRNA, which is the first molecule formed in the transcription process. The pre-mRNA is not ready for use and will need to go through some biochemical processes that will transform it into an mRNA molecule ready to be used.

The most important process that occurs right now is the removal of non-coding sequences from the pre-mRNA. These sequences can be considered "garbage" and will have no use in the protein formation process.
