DNA Structure and Function Assessment

The video tutorial introduces DNA as the biological blueprint of life, discovered in 1953. It explains how genetic information is inherited from parents and stored in DNA, which is composed of nucleotides forming a double helix structure. The tutorial also includes a hands-on activity to simulate DNA replication, encouraging students to explore the process practically.

When was the structure of DNA discovered?

• December 25, 1945

• January 1, 1960

• March 15, 1950

• February 28, 1953

What does each species have in one of its cells?

• A special enzyme

• A code for its development

• A unique protein

• A distinct carbohydrate

How is genetic information inherited?

• Entirely from the mother

• Entirely from the father

• Half from the mother and half from the father

• Randomly from either parent

What are the building blocks of DNA called?

• Lipids

• Nucleotides

• Carbohydrates

• Amino acids

Which of the following is NOT a nucleotide in DNA?

• Adenine

• Cytosine

• Thymine

• Guanine

What shape does the DNA structure form?

• Double helix

• Circular loop

• Single strand

• Triple helix

What does each daughter cell receive during DNA replication?

• A different genetic code

• No genetic information

• Identical genetic information to the mother cell

• Half of the genetic information

What additional information does DNA contain besides genetic information?

• Instructions for cell function

• Cellular waste products

• Environmental data

• Nutritional information

What materials are suggested for the practical activity?

• Wood and nails

• Plastic and scissors

• Paper and glue

• Cardboard and adhesive tape
