100

This is what DNA stands for.

What is Deoxyribonucleic Acid?

100

This enzyme unzips DNA during replication.

What is helicase?

100

This does RNA stand for.

What is Ribonucleic Acid?

100

This process copies DNA into RNA.

What is transcription?

100

Translation occurs at this organelle.

What is the ribosome?

200

This is the shape of DNA.

What is a double helix?

200

This enzyme adds complementary nucleotides.

What is DNA polymerase?

200

This sugar is found in RNA.

What is ribose?

200

Transcription occurs in this part of the cell.

What is the nucleus?

200

A three-base sequence on mRNA is called this.

What is a codon?

300

These are the three parts of a DNA nucleotide.

What are phosphate, deoxyribose sugar, and nitrogen base?

300

This term describes replication where each new DNA molecule has one original strand.

What is semi-conservative replication?

300

This nitrogen base replaces thymine in RNA.

What is uracil?

300

This enzyme builds the RNA strand.

What is RNA polymerase?

300

The start codon is this sequence.

What is AUG?

400

This base pairs with guanine.

What is cytosine?

400

Put these steps in order:
• Helicase unwinds DNA
• DNA polymerase adds nucleotides
• Two identical DNA molecules form

What is: helicase unwinds → DNA polymerase adds nucleotides → two identical DNA molecules form?

400

Name two differences between DNA and RNA.

(Examples: single vs double stranded, ribose vs deoxyribose, uracil vs thymine.)

400

If the DNA template strand is TAC GGA CTT, this is the mRNA sequence.

What is AUG CCU GAA?

400

Translate this sequence: AUG GCU UAC UGA.

What is Methionine – Alanine – Tyrosine – Stop?

500

If a DNA strand reads ATC GGA TTA, this is the complementary strand.

What is TAG CCT AAT?

500

If the strand is TAC GCA TTT, this is the new complementary strand.

What is ATG CGT AAA?

500

This type of RNA brings amino acids to the ribosome.

What is tRNA?

500

During transcription, adenine pairs with this base.

What is uracil?

500

If a base is deleted from DNA, this type of mutation may occur.

What is a frameshift mutation?
