12 Questions
What is the significance of Mendel's Law of Segregation in genetics?
It explains how alleles segregate during gamete formation.
Why did Mendel focus on the F2 generation to determine the ratio of dominant to recessive traits?
The F2 generation had a higher number of offspring for statistical accuracy.
What distinguishes a heterozygous organism from a homozygous organism?
Heterozygous organisms have two different gene copies, while homozygous organisms have two identical gene copies.
What made Mendel's study with garden peas stand out compared to his initial work with mice and honeybees?
Garden peas allowed for controlled crosses and clear trait observations.
In Mendel's experiments, what did the term 'recessive' signify?
Traits that are hidden in the F1 generation but reappear in the F2 generation.
What fundamental concept in genetics does Mendel's choice of garden peas as an experimental organism demonstrate?
The significance of controlled experiments in studying inheritance.
What is the significance of the semiconservative mechanism of DNA replication?
It ensures the exact duplication of genetic material in cells.
Which enzyme is primarily responsible for mediating DNA replication?
RNA polymerase
How does gene editing differ from gene cloning?
Gene editing alters specific genes within an organism, whereas gene cloning inserts foreign DNA into a host.
What is the primary role of plasmids in recombinant DNA technology?
Serving as carriers for foreign DNA fragments
What experimental evidence supported the existence of complementary base pairing in DNA?
Research by Watson and Crick in understanding Chargaff's rule
Which discovery provided a physical representation for genes and facilitated further genetic studies?
Watson and Crick's elucidation of DNA structure
Explore Mendel's choice of garden peas for genetic experiments, his terminology for trait forms, and the concepts of dominant and recessive traits across generations. Learn how he calculated the ratio of dominant to recessive traits using Punnett squares.
