DNA Structure
DNA stands for this.
What is deoxyribonucleic acid?
The stage of the cell cycle where DNA is replicated.
What is interphase (S phase)?
The two main nucleic acids found in cells.
What are DNA and RNA?
This process copies DNA into mRNA.
What is transcription?
Gene expression is the process by which genes make this.
What are proteins?
This shape describes the structure of DNA.
What is a double helix?
This process produces two genetically identical cells.
What is mitosis?
This sugar is found in RNA but not DNA.
What is ribose?
This process uses mRNA to assemble amino acids.
What is translation?
Turning genes on or off is called this.
What is gene regulation?
These molecules make up the sides of the DNA ladder.
What are sugar and phosphate?
Chromosomes line up at the equator of the cell in this phase.
What is metaphase?
This nitrogen base replaces thymine in RNA.
What is uracil?
This type of RNA carries amino acids to the ribosome.
What is tRNA?
A mutation that changes one nucleotide.
What is a point mutation?
These nitrogen bases pair together in DNA.
What are A–T and C–G?
This process divides the cytoplasm.
What is cytokinesis?
The basic building block of nucleic acids.
What is a nucleotide?
This cell structure reads mRNA to build proteins.
What is the ribosome?
This mutation shifts the reading frame.
What is a frameshift mutation?
This type of bond holds complementary bases together.
What are hydrogen bonds?
Uncontrolled cell division can lead to this disease.
What is cancer?
DNA stores instructions for making these.
What are proteins?
A three-base sequence on mRNA.
What is a codon?
Environmental agents that cause mutations.
What are mutagens?
