Double helix In DNA, adenine pairs with __________________. Thymine A nucleotide is made up of what 3 parts? Phosphate, sugar, and base What does DNA stand for? Deoxyribonucleic acid If there is 40% of cytosine, how much Adenine is there? 10% Adenine What is the purpose of replication? To copy DNA What stage of the cell cycle does replication take place in? Synthesis Where does replication take place? Nucleus What is the enzyme that binds nucleotides together? Polymerase If a template strand is AATTCC, what is the pairing strand? TTAAGG What is the purpose of transcription? To make an RNA message Where does transcription take place? nucleus Which type of RNA brings amino acids to the ribosomes? tRNA What type of RNA makes up a part of the ribosome? rRNA Transcribe AATTCC UUAAGG Transcription uses the whole DNA strand or one gene? One gene The purpose of translation is to make protein Where does translation take place? ribosome A chain of amino acids makes protein A set of 3 nucleotides is called a codon Find the amino acid for GUC Val A mutation where one nucleotide is substituted for another Point mutation A mutation where a nucleotide is added to the sequence Addition or Insertion Mutation A mutation in which a nucleotide is removed from the sequence Deletion What type of mutation? DNA 1: AATTCCGG DNA 2: AATACCGG Point What type of muation? DNA 1: AATTGGCC DNA 2: AATTGCC Deletion
