DNA and RNA Name: Biology 5.0 Date: Period: Comparing DNA and RNA Transcription and Translation Practice Read each term or phrase in the left-hand column of the following table. If the term or phrase applies to DNA, place a check mark in the column labeled DNA. If it applies to RNA, place a check mark in the column labeled RNA. If it applies to both nucleic acids, place a check mark in both columns. Place the terms in the Venn Diagram. Term or Phrase: Nucleotides Deoxyribose Ribose Single-stranded Double-stranded Nitrogen bases Thymine Uracil Double Helix Replication Transcription Messenger More than one form Found in the nucleus Leaves the nucleus Does not leave the nucleus DNA DNA RNA RNA Transcription and Translation Practice: Example: A certain gene has the following sequence of nucleotides: GACAAGTCCACAATC Write the sequence of the mRNA molecule that is transcribed from this gene. Using the amino acid charts, write the amino acid sequence of the polypeptide translated from the mRNA. Practice: 1. Transcribe each of the following sequences from DNA to mRNA. Then translate each mRNA sequence into amino acids: a) A G C T C A T G C C A G b) T C A G A T C A A G T C c) C A G T C T G A A T C A d) T A C A G T C C A G T A C G G 2. Given the sequence A T G G C G A A T C A C G T C A C T T G A a) Write the sequence of nucleotides for the complementary strand of DNA. b) Write the mRNA sequence transcribed from the complementary strand. c) What is the tRNA sequence that would be used to translate this sequence? d) Convert the message into an amino acid sequence.
