Imagine you're in a DNA lab with Priya, Noah, and Liam. Which of the following is NOT a component of the DNA or RNA nucleotides you're examining?

• Sugar

• Phosphate

• Amino Acid

• Nitrogen Base

Ethan and Anika are exploring the world of DNA. Can you help them find the correct base pairing for DNA?

• A ↔ G, C ↔ T

• G ↔ C, A ↔ T

• U ↔ C, G ↔ T

• A ↔ U, C ↔ G

Imagine you're a tiny scientist inside a cell, why is mRNA your trusty assistant in the cell's bustling lab?

• It adds amino acids to a growing protein chain.

• It is responsible for adding ribose sugars to DNA.

• It brings a transcript (copy) of DNA to a ribosome.

• It stores information in the nucleus.

Imagine you're on a treasure hunt with Ava, David, and Hannah! Which of the following represents the correct order of structures from the tiniest treasure to the grandest prize?

• Gene, Chromosome, Nucleotide, DNA Strand

• Chromosome, Nucleotide, DNA Strand, Gene

• Nucleotide, Gene, DNA Strand, Chromosome

• DNA Strand, Nucleotide, Chromosome, Gene

Imagine you're in a science adventure with Liam and Sophia, exploring the wonders of the cell! The diagram to the right shows the magical process of protein synthesis. What process does the picture represent in this cellular journey?

• DNA replication

• Transportation

• Transcription

• Translation

Where would you find the secret recipe to make a protein?

• In tRNA

• In DNA

• In ribosomes

• In other proteins

Why is the 3D shape of proteins like a secret superpower in the cell?

• Just like a superhero's costume, the shape of a protein determines its function in the cell and the organism. Ask Samuel, he knows!

• Grace thinks the shape of a protein decides what kind of carbohydrate it will become. Is she right?

• Abigail believes the shape of a protein can change based on what the cell needs it to do. What do you think?

• Does the shape of a protein change the DNA sequence that it will code for? Maybe ask Samuel!

Imagine you're a detective, solving the mystery of how proteins work! The function of a protein is like its superpower, determined by its _________, which is like the secret code made up of _____

• DNA, shape

• Shape, amino acids

• Amino acids, DNA

• Amino acids, shape

In a magical garden, Priya and Liam are observing pea plants. They notice that being tall (T) is like having a magical power, dominant over being short (t). If a super tall plant (TT) marries a tiny short plant (tt), what magical genotypes will their offspring have?

• TT only

• tt only

• Tt only

• TT and tt
