Which molecule directs the synthesis of a polypeptide at a ribosome? Which of the following identifies the process shown at point Z?
Understand the Problem
The question is asking which molecule directs protein synthesis at a ribosome and identifies a cellular process depicted in a provided diagram. It refers to the roles of different molecules such as RNA, DNA, and other related processes.
Answer
RNA directs synthesis; Translation at point Z.
The molecule that directs the synthesis of a polypeptide at the ribosome is RNA. The process at point Z is translation.
Answer for screen readers
The molecule that directs the synthesis of a polypeptide at the ribosome is RNA. The process at point Z is translation.
More Information
Messenger RNA (mRNA) is the type of RNA that carries genetic information from the DNA to the ribosome, where it is translated into a protein.
Tips
A common mistake is confusing transcription with translation. Remember, transcription is making RNA from DNA, while translation is synthesizing proteins from RNA.
