- Evidence of Evolution: Universal Genetic Code All organisms use DNA to store genetic information (with the exception of some viruses). They all use the same four bases (G, A, C,…

- Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. Bacteria, fungi, cats, plan…

- Species that have a common ancestor have similar DNA and RNA. The more closely they are related, the more similar their DNA is. Using the "tree of life" above, determine which o…
- What does the universal genetic code imply?
- Whales and dolphins have 20 nucleotide differences on the gene coding for fat production. Whales and hippos have 80 nucleotide differences on the same gene. What does this demon…
- Which of these statements allows scientists to calculate the approximate time since speciation of two species occurred?
- Which from the list are characteristics that a multicellular organism MUST have?
- Which of these characteristics is shared by both eukaryotes and prokaryotes?
- What molecule is the universal genetic code made up of?
- What accounts for differences between organisms?
- What are the four bases of DNA?
- What nucleotides are used in RNA?
- DNA and RNA contain sequences that allow proteins to be constructed by ribosomes. Three-nucleotide-long sequences called codons correspond to amino acids. Almost every organism …
- You are studying three kinds of bacteria. A gene for a segment of their ribosomes, the 16S gene, can be compared in order to determine how the bacteria are related. If bacteria …

- This is a standard version of the genetic code. You have a segment of DNA that reads ATCGTCAAT. What sequence of amino acids would it code for?
- There are 4 DNA nucleotide bases. There are 3 nucleotides in a codon. How many possible codons are there, and how does it relate to there being about 20 natural amino acids?
