BIOL 110 Study Guide - Midterm Guide: Okazaki Fragments, Dna Ligase, Dna Replication
Document Summary
During prophase i, when homologous chromosomes pair and line up, they may swap genetic material called crossing over . Linked genes- genes located on same chromosome, tend to be inherited together. Closer the genes are, higher probability to be inherited together. Linkage map- shows sequence of genes along chromosome. Central dogma- dna codes for the synthesis of proteins through transcription and translation. Dna template strand is used to make mrna. **m rna is complementary to dna template and same as the coding strand of dna** Transcription occurs in the nucleus rrna- combines with proteins to form ribosomes. **anticodons are complementary to mrna** translating- making the protein ; 3 stages- iniation, elongation, termination. Population- group of organisms that are members of the same species. Species- group of potentially interbreeding individuals that ccan produce fertile of spring. Bottleneck efect- event that decimates a population and leaves only a few surviving individuals. Founder efect- when a few individuals become geographically separate.
