Question

question 11
which of the following is found in eukaryotic genes but not prokaryotic genes?
○ operons
○ repressors
○ introns
question 12
the genetic makeup of an organism and its physical appearance are its ____ and ____, respectively.
○ genotype; phenotype
○ gender; sex
○ phenotype; genotype

Explanation:

Question 11

• Operons are mainly found in prokaryotic genes for coordinated gene regulation.
• Repressors are present in both prokaryotic and eukaryotic gene regulation.
• Introns are non - coding regions in eukaryotic genes that are spliced out during RNA processing, and prokaryotic genes generally lack introns.

• Genotype refers to the genetic makeup (the set of genes) of an organism.
• Phenotype refers to the physical appearance or observable characteristics of an organism, which is determined by the genotype and environmental factors.
• "gender; sex" is incorrect as they are related to biological sex and social constructs of gender, not genetic makeup and physical appearance.
• The order "phenotype; genotype" is reversed as genotype is the genetic makeup and phenotype is the physical appearance.

Answer:

C. introns
