"Construct an explanation of how the structures of DNA and RNA lead to the expression of information within the cell via the processes of replication, transcription, and translation. "
Learning objective:
DNA and RNA are long molecules made of smaller pieces called nucleotides. DNA and RNA store genetic information that tells your cells how to work and grow. DNA and RNA are found in all living things.
DNA & RNA: The Building Blocks of Life
DNA: Deoxyribonucleic Acid is the genetic material found in almost all living organisms. RNA: Ribonucleic Acid is a molecule that helps create proteins in the body. Nucleotides: Nucleotides are the building blocks of DNA and RNA; each one contains one sugar, one phosphate, and one nitrogenous base.
Concepts:
Humans have about 3 billion base pairs of DNA in their genome. The human genome has more genes than any other organism. RNA can do many things that DNA cannot do, such as make proteins and transport genetic information.
Fun facts:

Work together in pairs: Q: What is the main difference between DNA and RNA that allows them to perform different functions within the cell?
Brain break: Create a drawing of a dragon using only one color and only three shapes (triangle, square, and circle). Make sure to include details such as eyes, wings, and scales.
What is the difference between DNA and RNA?
- DNA is double-stranded, while RNA is single-stranded.
- DNA is found inside the nucleus, while RNA is found in the cytoplasm.
- DNA is made of sugar and phosphate, while RNA is made of sugar and nitrogen.
- DNA is responsible for storing genetic information, while RNA is responsible for reading that information.
What are the four nitrogenous bases found in DNA?
- Thymine, Cytosine, Adenine, Guanine
- Cytosine, Adenine, Guanine, Uracil
