Explanation:
The founder effect is a type of genetic drift that occurs when a small group of individuals becomes isolated from a larger population, establishing a new population with a different allele frequency. This can lead to reduced genetic variation and increased prevalence of certain traits. Examples: high frequency of polydactyly in Amish community.
Explanation:
Entomology is the study of insects. Ichthyology is fish, herpetology reptiles and amphibians, ornithology birds. Insects are the most diverse group of animals.
Explanation:
During DNA replication, the lagging strand is synthesized discontinuously in short segments called Okazaki fragments. After the RNA primers are removed and replaced with DNA by DNA polymerase I, the fragments remain separated by nicks in the sugar-phosphate backbone. DNA ligase is the enzyme that catalyzes the formation of phosphodiester bonds between these fragments, sealing the nicks and creating a continuous DNA strand.
