DNA replication

All of the following are components of the cell theory, except..

• All living things are made up of cells

• All cells contain DNA

• New cells come from preexisting cells

• Cells are the basic unit of life

What is the difference between a prokaryotic cell and an eukaryotic cell?

• Prokaryotic cells have a nucleus

• Prokaryotic cells are more complex

• Eukaryotic cells have a plasmid

• Eukaryotic cells have a nucleus

What is meant by semiconservative replication?

• One strand from the parent DNA is maintained in the new copy

• A whole new DNA molecule duplicates, leaving the parent strand intact

• There is a mosaic pattern in each strand

• Newly replicated DNA molecule is different from the parent strand

What does the following picture represent?

• Nucleoside

• Nucleotide

DNA is synthesized in the ... direction, and read in the ... direction.

• 5' to 3, 5' to 3'

• 3' to 5', 3' to 3'

• 5' to 3', 3' to 5'

Which of the following best represents the Central Dogma?

• Maintaining genetic material

• Phenotype to genotype

• Loss of genetic material

• Genotype to phenotype

Select all that are true about DNA Polymerase

• Synthesize 5' to 3' direction only

• Can synthesize RNA

• Synthesize 3' to 5' direction only

• Cannot initiate synthesis de novo

Where does DNA replication starts?

• ORI

• Ribosome

• ORC

• MCM helicase

Why can't DNA Polymerase initiate synthesis de novo?

• It actually can

• It needs a primer

• DNA strands are antiparallel

• mRNA is not processed
