What is the building block of life? | Protein |
What is the code for building proteins? | Genes |
What was the question and still is? | What is the process by which we make protein and how is it related to our genetic material? |
What happened in the 1940s? | Basic building block of DNA is a sugar paired with a phosphate and 1 of 4 bases. |
What does DNA mean? | Deoxy Ribose Nucleic Acid |
What a sugar paired with 1 phosphate and one of 4 bases called? | Nucleotide |
