• TGAACT

• TCAAGT

• AGTTCA

• ACTTGA

What is the name of the sugar molecule found in DNA?

• ribose

• deoxyribose

• uracil

• dechlorane

Molecules 'A', 'B', and 'C' bonded together make up which molecule?

• Sugar

• Protein

• Amino Acid

• Phosphate group

• Nucleotide

Which of the following is NOT a component of DNA?

• nucleotides

• sugar molecules

• nitrogen bases

• phosphate group

• amino acids

The traits of an organism depend on what part of the DNA molecule?

• The type of sugar molecule

• The phosphate-sugar chain

• The shape of the DNA molecule

• The order of the nitrogen bases

DNA sequence is ACAGTGC. How would this be coded on mRNA?

• TGTCACG
• UGUCACG
• GUGACAU
• CACUGUA

This molecule carries genetic information from the nucleus to the ribosomes in the cytoplasm.

• rRNA
• tRNA
• mRNA
• DNA

What does Letter C indicate?

• Polypeptide Chain
• Anticodon
• Codon
• Amino Acid

What process is occurring in the diagram?

• Transcription
• Translation
• Replication
• Mitosis

Does the order of amino acids matter when making a protein?

• No, as long as it uses the right amount of each amino acid, the order does not matter

• No, a specific gene might code for a different amino acid chain each time

• Yes, a different order would give the protein a different shape

• Yes, two of the same amino acids cannot be linked together
