[6A] Which of these substances is found in DNA molecules?

• Glucose

• Uric Acid

• Nitric Acid

• Deoxyribose

[6B] Colonies of genetically engineered E.Coli bacteria produce human insulin that diabetics can use. Bacteria are able to produce proteins because both bacteria and humans-

• are both prokaryotes

• similar nucleotides are present in both

• are closely related

[6C] A model of a biological process in shown. What is the purpose of this process?

• To replicate the DNA of an organism before cell division

• to assemble nucleotides in an mRNA chain along a DNA template

• To synthesize amino acids used to unzip strands of DNA and copy the genetic code

• to translate the genetic code into a specific sequence of amino acids

[6D] Human bone, muscle, and nerve cells all contain the same number of chromosomes with the same complement of genes. What enables these cells to preform specialized activities?

• The ability of some cells to remove unnecessary DNA sequences

• The regulation of gene expression within each cell type

• The mutation of genes within each cell type

• The use of different methods of cell division

[6E] A point mutation in a gene leads to the transcription of a different mRNA codon than before. If the original codon was CGU, the mRNA codon that would most likely lead to the synthesis of an altered protein is-

• AGA

• AGU

• CGC

• CGG
