Understanding DNA and RNA

What is the primary genetic material found in all organisms?

• DNA

• Proteins

• Carbohydrates

• RNA

What is the process of copying DNA called?

• Replication

• Transcription

• Translation

• Mutation

What does the Central Dogma of molecular biology describe?

• The replication of DNA

• The transformation of bacteria

• The genetic engineering process

• The flow of genetic information from DNA to RNA to protein

What is genetic engineering primarily concerned with?

• Modifying organisms by manipulating their DNA

• Mapping the human genome

• Discovering new antibiotics

• Studying the history of genetics

What did the Avery-MacLeod-McCarty experiment demonstrate?

• DNA is the hereditary material

• Proteins are the hereditary material

• RNA is responsible for protein synthesis

• Viruses can inject DNA into bacteria

Which experiment conclusively proved that DNA is the genetic material?

• Avery-MacLeod-McCarty experiment

• Frederick Griffith experiment

• Watson and Crick's model

• Hershey-Chase experiment

What rule did Erwin Chargaff discover?

• The double helix structure of DNA

• The process of DNA replication

Who are credited with the discovery of the structure of DNA?

• Avery, MacLeod, and McCarty

• Hershey and Chase

• Watson and Crick

• Franklin and Wilkins

What are histones?

• Enzymes that replicate DNA

• Proteins around which DNA is wrapped in eukaryotic chromosomes

• Segments of DNA that code for proteins

• Bacterial DNA loops

What is the significance of plasmids in bacteria?

• They protect bacteria from viruses

• They can carry additional genes and be exchanged between bacteria

• They assist in the replication of bacterial DNA

• They are the main source of genetic material
