DNA Structure and Replication Quiz

List an enzyme used during DNA replication.

Where is DNA mainly located in a cell?

• Cytoplasm

• Cell membrane

• Nucleus

• Ribosome

What was DNA named after its location in the cell?

• Amino acid

• Fatty acid

• Nucleic acid

• Carboxylic acid

Draw a double stranded segment of DNA, showing both strands, including at least 5 bases on each strand (make sure to match them), label where the sugar and phosphate would be and include 5' and 3' in your diagram.

One vital function of (a)   is the ability to make copies of itself so that genetic information can be passed from cell to cell and on to the next (b)   . The process that enables this to occur is called (c)   and occurs in both (d)   and (e)   cells.

• DNA
• generation
• DNA replication
• prokaryotic
• eukaryotic

What structures serve as the cell's structural units of information?

• Chromosomes

• Ribosomes

• Mitochondria

• Lysosomes

Okazaki fragments are short segments of DNA that are formed on the (a)   during DNA replication. Since DNA can only be built in one direction (from 5' to 3'), the lagging strand is synthesized in small pieces as the DNA (b)   . Each Okazaki fragment is created when DNA polymerase adds (c)   to the exposed template strand. Once all the fragments are made, another enzyme connects them to form a (d)   DNA strand.

• lagging strand
• unwinds
• nucleotides
• continuous

Which structure is common to both prokaryotic and eukaryotic cells?

• Chloroplast

• Ribosomes

• Nucleus

• Golgi apparatus

Which structure is unique to eukaryotic cells?

• Nucleoid

• Ribosomes

• Nucleus

• Cell wall

Which organelle is responsible for energy production in eukaryotic cells?

• Golgi apparatus

• Mitochondria

• Lysosome

• Vacuole
