DNA history, DNA and RNA. Team #4

Which molecule is primarily responsible for storing genetic information in living organisms?

• RNA

• DNA

• Protein

• Carbohydrate

The discovery of the double helix structure of DNA is credited to:

• Franklin

• Sanger

• Watson and Crick

• Chargaff

Chargaff's rules state that in DNA:

• Adenine always bonds with Cytosine.

• Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C).

• All bases bond with each other equally.

• RNA has a higher concentration than DNA.

The process of making a complementary RNA copy from a DNA template is called:

• Replication

• Transcription

• Translation

• Mutation

Which type of RNA carries the genetic code from DNA to ribosomes for protein synthesis?

• Transfer RNA (tRNA)

• Messenger RNA (mRNA)

• Ribosomal RNA (rRNA)

• All of the above

Unlike DNA, RNA molecules are typically:

• Single-stranded

• Double-stranded

• Made up of Ribose sugar

• All of the above

Mutations in DNA can occur due to

• Errors during replication

• Exposure to environmental factors

• All of the above

The process of using the genetic code in mRNA to build a specific protein is called:

• Transcription

• Replication

• Translation

• Mutation

The Human Genome Project aimed to:

• Sequence the entire human DNA

• Sequence the entire human DNA

• Develop gene therapy techniques

• Create genetically modified organisms

DNA fingerprinting is a technique used for:

• Gene editing

• Creating clones

• Identifying individuals based on their unique DNA patterns

• Studying gene expression
