DNA Replication

Why is it crucial that living things are able to replicate their DNA?

• Each cell must have its own DNA
• Less copies of DNA are needed when a new cell is created
• A cell needs multiple copies of DNA
• Only muscle cells need DNA

Which of the following units are repeatedly joined together to form a strand of DNA?

• Amino Acids

• Nucleotides

Why does DNA replicate?

• To create a duplicate copy in case the original gets damaged

• New cells will have a copy of the DNA

• To create a new copy to replace the damaged original
