Question

In 3–4 sentences, construct a summary of the process of gene expression, starting with DNA and ending with proteins. Please make your answer simple, yet coherent, and intended for 9th grade.

Answer 1

Gene expression is the process by which the information in DNA is used to make proteins, which are crucial for many functions in living organisms. It starts when a gene on the DNA is copied into a molecule called messenger RNA (mRNA) through a process called transcription. The mRNA then travels out of the nucleus to the ribosome, where another process called translation occurs, creating a protein by linking together amino acids in a specific order according to the instructions in the mRNA. This means that the DNA, mRNA, and proteins all work together to help cells function properly.
