• Gregor Mendel and Charles Darwin

• Rosalind Franklin and Maurice Wilkins

• Barbara McClintock and Thomas Hunt Morgan

Multiple Choice

Which of the following explains the concept of the 'Central Dogma of Genetics' ?

• Gene expression is a two step process of protein synthesis

• Genes are unrelated to proteins, allowing them to change

• The flow of information goes from DNA to RNA to Protein to RNA and out of the cell

• Francis Crick explained the central dogma of not knowing why we have RNA

Multiple Select

Which of the following are steps involved in protein synthesis?

• Transcription from DNA to RNA

• Replication from DNA to DNA

• Reverse transcription from RNA to DNA

Multiple Choice

During a biology class, Ms. Serrano noticed that Michael had a scab on his hand. Shakira and London were curious about how the scab formed. They wondered what role genes play in this process. Can you help them understand?

• Genes provide instructions for making proteins that aid in scab formation

• Genes regulate blood flow to the wound area

• Genes produce antibodies to fight off infection at the wound site

• Genes control hormone production that influences scab formation
