DNA Replication & Process Review

What is DNA replication?

• The process of making proteins

• The process of cell movement

• The process of copying DNA before a cell divides

• The process of breaking down DNA

During DNA replication, what happens to the two strands of DNA?

• They break into random pieces

• They merge into one strand

• They separate and each one serves as a template for a new strand

• They disappear and reform later

Where does DNA replication mainly occur?

• In the cytoplasm

• In the mitochondria

• In the ribosomes

• In the nucleus

Why is DNA replication important before cell division?

• To produce extra energy

• To help the cell move

• So that each new cell gets a complete set of instructions

• To create more proteins

Which process copies DNA into mRNA?

• Translation

• Transcription

• Replication

• Transformation

Which process uses mRNA to build proteins?

• Replication

• Transcription

• Transformation

• Translation

Where does transcription occur?

• In the cytoplasm

• In the nucleus

• On ribosomes

• In the mitochondria

Where does translation occur?

• In the nucleus

• In the cell membrane

• In the mitochondria

• In the cytoplasm on ribosomes

During DNA replication, which rule is followed to create a new strand?

• Codon rule

• Genetic code

• Base pairing rule

• Transcription rule

Why do daughter cells need a complete copy of DNA?

• To build the cell wall

• To have all genetic instructions for cell function

• To create more energy

• To digest food
