What is the relationship among DNA, a gene, and a chromosome?
a. A chromosome contains hundreds of genes which are composed of protein. b. A chromosome contains hundreds of genes which are composed of DNA. c. A gene contains hundreds of chromosomes which are composed of protein. d. A gene is composed of DNA, but there is no relationship to a chromosome. e. A gene contains hundreds of chromosomes that are composed of DNA. 14. DNA has two functions: it can self-replicate and it can make non-DNA molecules. DNA is capable of this because; a. It has two strands held together by easily broken electrostatic attractions. b. Its nucleotides will form base pairs with both ribose and deoxyribose nucleotides. c. Both DNA and proteins can be synthesized directly at the DNA template. d. Its replication is semi-conservative. e. Replication and gene expression are spontaneous and require no enzymes. 15. A particular triplet of bases in the coding sequence of a DNA is 3’AGT5′. What is the corresponding triplet in the complementary strand of DNA? a. 5’AGT3′ b. 5’U
