Key qConcepts
• Inherited q traits qare q affected qby qgenes.
• Genes q are q composed q of q the q chemical q deoxyribonucleic q acid q (DNA).
• DNA qreplicates q to q form q (usually q identical) q copies q of q itself.
• DNA qcontains qa qcode qspecifying qwhat qtypes qof qenzymes qand qother qproteins
qare qmade qin qcells.
• DNA qoccasionally qmutates, q and qthe qmutant qforms qspecify qaltered qproteins.
• A qmutant qenzyme qis qan q"inborn qerror qof qmetabolism" qthat qblocks qone qstep
qin qa qbio- qchemical qpathway qfor qthe qmetabolism qof qsmall qmolecules.
• Traits qare qaffected qby qenvironment qas qwell qas qby qgenes.
• Organisms qchange qgenetically qthrough qgenerations qin qthe qprocess qof
qbiological qevolution.
• Because qof qtheir qcomm.on qdescent, qorganisms qshare qmany qfeatures qof qtheir qgenetics
and qbiochemistry.

1.1. (a) qfalse; q(b) qtrue; q(c) qtrue; q(d) qfalse.
1.2. The qimportance qof qthe qnucleus qin qinheritance qwas qimplied qby qits
qprominence qin qfer- qtilization. qThe qdiscovery qof qchromosomes qinside qthe
qnucleus, qtheir qbehavior qduring qcell qdivision, qand qthe qobservation qthat qeach
qspecies qhas qa qcharacteristic qchromosome qnumber qmade qit qlikely qthat
qchromosomes qwere qthe qcarriers qof qthe qgenes. qMicro- qscopic q studies
q showed q that q DNA q and q proteins q are q both q present q in q chromosomes, qbut
qwhereas qnearly qall qcells qof qa qgiven qspecies qcontain qa q constant qamount qof
qDNA, qthe qamount qand qkinds q of qproteins qdiffer qgreatly qin qdifferent qcell
qtypes.
