How does complementary base pairing facilitate DNA replication and the processes of transcription and translation? Give your answers in the appropriate thread During DNA replication the double stranded structure of DNA allows each original strand to serve as a template for the formation of a complementary new strand. Before replication begins, the two strands that make up parental DNA are hydrogen-bonded together by complementary paired bases. During the process of transcription the DNA serves as a template for production of an RNA molecule. A portion of DNA unwinds and unzips at the pint of attachment of RNA polymerase. A strand of mRNA is

Unformatted text preview: produced when complementary bases join in the order dictated by the sequence of bases in template DNA. During translation tRNA molecules bring amino acids to the ribosome where polypeptide synthesis occurs. Each ribosome has a binding sits for mRNA as well as the binding sites for two tRNA at a time. The amino acids bind to one end of the tRNA, therefore the entire complex is designated at tRNA amino acids. At the other end of each tRNA is a specific anticodon a group of three bases complementary to an mRNA codon. The tRNA attach to the ribosome at the amino acid site where each anitcodon pairs by hydrogen bonding with codon....
