question 82

Multiple Choice

DNA polymerase catalyzes elongation of DNA chains

• A) in the 5' to direction through the addition of a deoxyribonucleotide complementary to the primer.
• B) in the to 5' direction through the addition of a deoxyribonucleotide to the OH of the primer strand.
• C) in the 5' to direction through the addition of a ribonucleotide to the OH of the primer strand selecting a purine or pyrimidine base complementary to the template strand.
• D) in the to 5' direction through the addition of a deoxyribonucleotide to the OH of the primer strand selecting a purine or pyrimidine base complementary to the template strand.
• E) in the 5' to direction through the addition of a deoxyribonucleotide to the OH of the primer strand selecting a purine or pyrimidine base complementary to the template strand.

Definitions:

Speciation

The evolutionary process by which populations evolve to become distinct species, primarily through genetic divergence and reproductive isolation.

Evolutionary Processes

The natural mechanisms that lead to changes in genetic composition of populations over successive generations.

Cladogenesis

An evolutionary splitting event where a single lineage divides into two distinct lineages, leading to increased biodiversity.

Anagenesis

The gradual evolution of a species to a new form, without branching or diversification into multiple species.
