Heredity Code Quiz

What is the function of DNA replication?

• To repair damaged DNA

• To create new cells

• To pass on genetic information from parent to offspring

• To produce proteins

What is the structure of a DNA molecule?

• Double helix

• Single strand

• Triple helix

• Circular

Which enzyme unwinds the DNA for replication?

• RNA primase

• DNA polymerase

• DNA helicase

• Topoisomerase

What is the purpose of RNA primers in DNA replication?

• To initiate DNA polymerase

• To unwind the DNA

• To remove RNA primers

• To repair damaged DNA

What is the difference between the leading and lagging strands in DNA replication?

• The leading strand is replicated in the 3' to 5' direction, while the lagging strand is replicated in the 5' to 3' direction

• The leading strand is replicated in the 5' to 3' direction, while the lagging strand is replicated in the 3' to 5' direction

• The leading strand is replicated in fragments, while the lagging strand is replicated continuously

• The leading strand is replicated continuously, while the lagging strand is replicated in fragments

Where does DNA replication occur in prokaryotes?

• Endoplasmic reticulum

• Mitochondria

• Nucleus

• Cytoplasm

What did Gregor Mendel study in his experiments?

• Patterns of inheritance in bacteria

• Patterns of inheritance in animals

• Patterns of inheritance in humans

• Patterns of inheritance in pea plants

What is the genotype of an organism?

• Its recessive traits

• Its genetic makeup

• Its observable characteristics

• Its dominant traits

What is the law of segregation?

• Dominant genes mask recessive traits

• Offspring inherit one allele from each parent

• Genes for different traits are sorted independently

• Alleles for a trait separate during meiosis

What is the law of independent assortment?

• Genes for different traits are sorted independently

• Alleles for a trait separate during meiosis

• Offspring inherit one allele from each parent

• Dominant genes mask recessive traits
