2. Requires RNA to send messages out to organelles
Answers may vary
What type of bonds form between the nitrogenous bases of DNA?
Weak Hydrogen Bonds
What is the role of the anticodon in the process of translation?
The anticodon binds to a codon on mRNA.
What are the 2 main steps (processes) of protein synthesis
Transcription and Translation
At a point in the cell cycle, chromosomes have aligned near the middle of a cell. Which sequence of events will the cell need to complete to produce two identical daughter cells?
anaphase → telophase → cytokinesis
