SOLUTION SET
◉ Deoxyribose :: 5-carbon sugar found in DNA. Answer:
◉ Phosphate group :: connects sugars to form the DNA backbone.
Answer:
◉ Sugar-phosphate backbone :: alternating chain of sugars and
phosphates in DNA. Answer:
◉ Phosphodiester bond :: covalent bond linking the 3′ carbon of one
sugar to the 5′ carbon of the next. Answer:
◉ 5′ end :: end of DNA with a free phosphate group. Answer:
◉ 3′ end :: end of DNA with a free OH group. Answer:
◉ Antiparallel :: DNA strands run in opposite directions (5′→3′ and
3′→5′). Answer:
◉ Complementary base pairing :: specific pairing of bases (A-T, G-C).
Answer:
, ◉ Hydrogen bonds :: weak bonds that hold base pairs together. Answer:
◉ Transformation :: uptake of foreign DNA by a cell. Answer:
◉ Cotransformation :: two genes taken up together because they are
close on DNA. Answer:
◉ Linkage :: genes located near each other on a chromosome. Answer:
◉ Gene mapping :: determining gene order based on recombination or
cotransformation. Answer:
◉ Circular chromosome :: DNA arranged in a loop in bacteria. Answer:
◉ Chromatin :: DNA and protein complex in eukaryotic cells. Answer:
◉ Histones :: proteins DNA wraps around. Answer:
◉ Nucleosome :: DNA wrapped around histone proteins. Answer:
◉ Chromosome :: condensed structure of DNA containing genes.
