Document Summary

A gene can be fined as a region of dna that can be expressed to produce a final functional product, either a polypeptide or an rna molecule. Briefly explain how information flows from gene to protein. Describe and draw the processes of transcription and translation. Explain what it means to say that the genetic code is redundant and unambiguous. Include the following terms in a description of transcription: rrna, rna polymerase, the promoter, the terminator, the transcription unit, initiation, elongation, termination, introns, and exons. Include the following terms in a description of translation: trna, ribosomes, imitation, elongation, termination. A new era of biology began in 1859 when charles darwin published the origin of species. The origin of species focused biologists" attention on the great diversity of organisms. Darwin noted that current species are descendants of ancestral species. Evolution can be defined by darwin"s phrase descent with modification. Evolution can be viewed as both a pattern and a process.
