2. How does RNA differ from DNA

• RNA is single-stranded while DNA is double-stranded

• RNA has the base Uracil instead of Thymine

• RNA contains ribose sugar instead of deoxyribose sugar

• RNA can leave the nucleus while DNA can't

• All the above are true

What molecule of RNA is made from DNA in the nucleus?

• tRNA

• rRNA

• mRNA

4. What is the name of the process that makes a mRNA from DNA?

• Transcription

• Translation

5. What is the name of the process that takes mRNA and codes for the proteins?

• Transcription

• Translation

6. What is the correct sequence of events in protein synthesis?

• Protein --> RNA --> DNA

• DNA --> RNA --> Protein

• DNA --> protein --> RNA

• RNA --> DNA --> Protein

Answer explanation

DNA is locked inside the nucleus. It hold the recipe for making a protein. It first makes a messenger called mRNA to get the code out of the nucleus. The mRNA leaves the nucleus and attaches to a ribosome (kitchen). The mRNA tells the cell what amino acids (ingredients) to string together to make the protein. The tRNA bring the amino acids in order. DNA --> RNA --> Protein
