1. Complementary DNA and/or RNA molecules pair with each other by hydrogen bonding during replication, transcription, or translation. Which of the following pairs of molecules are complementary? (Select all that apply) * tRNA and mRNA Template DNA and tRNA mRNA and template DNA Coding DNA and mRNA Feedback Correct! tRNA is complementary to the mRNA. This is how the tRNA is able to place the appropriate amino acid is the growing polypeptide chain during translation. Correct! mRNA and template DNA are complementary. RNA polymerase creates the mRNA strand by reading the template and placing the complementary nucleotide in the 5'­3' direction during transcription. 2. During DNA replication the parent strands ______ and DNA polymerase______. * 1/1 separate, creates the new DNA strands separate, seals the DNA backbone serve as primers, creates the new DNA strands serve as primers, seals the DNA backbone Feedback Correct! During DNA replication the parent strands separate and DNA polymerase creates the new DNA strands. 3. The following sequence is one strand of the DNA that makes up the SNCA gene that codes for alpha­synuclein, a protein found in the brain. 5' ATGCGGTGACGG 3’ Which of the following is the complementary second DNA strand? *
