Nucleic acids and proteins
Nucleic acids and proteins are examples of important types of biomacromolecules. These include DNA, mRNA, tRNA and rRNA. Understanding their structures and functions, including the processes involved in the creation and secretion of proteins is important in biology. Certain proteins will need to be transported outside the cells that produce them. Understanding the secretion process and the role of the organelles involved is essential.
This resource revises nucleic acids and proteins and within nucleic acids and proteins there are 4 key concepts:
- The structure and function of nucleic acids
- Transcription and translation
- Protein structure and function
- The protein secretory pathway.
To determine if this resource will benefit you, start by answering the following questions.
- What are the similarities and differences in DNA and RNA structure and functions?
- How are proteins created from a gene?
- What is meant by ‘hierarchy of structure’ of a protein?
- How do enzymes work?
The answers to these questions are provided on the following pages. Use this resource to refresh your memory, reinforce your understanding of these concepts, and prepare more effectively for university-level learning.
