, The Genetic Code of Genes
and Genomes
Key Concepts
• Inherited s traits sare s affected sby sgenes.
• Genes s are s composed s of s the s chemical s deoxyribonucleic s acid s (DNA).
• DNA sreplicates s to s form s (usually s identical) s copies s of s itself.
• DNA scontains sa scode sspecifying swhat stypes sof senzymes sand sother sproteins sare
smade sin scells.
• DNA soccasionally smutates, s and sthe smutant sforms sspecify saltered sproteins.
• A smutant senzyme sis san s"inborn serror sof smetabolism" sthat sblocks sone sstep sin
sa sbio- schemical spathway sfor sthe smetabolism sof ssmall smolecules.
• Traits sare saffected sby s environment sas swell sas sby sgenes.
• Organisms schange sgenetically sthrough sgenerations sin sthe sprocess sof
sbiological sevolution.
• Because sof stheir scomm.on sdescent, sorganisms sshare smany sfeatures sof stheir sgenetics
and sbiochemistry.
Key sTerms
1. complementary sbase spairing
2. antiparallel
3. central sdogma
4. transcri s tion
5. ribosome
6. transfer s RNA s (tRNA)
7. proteome
8. substrate
9. alkaptonuria
10. phenylketonuria
11. pleiotropic seffect sor spleiotropy
12. prokaryote

1.1. (a) sfalse; s(b) strue; s(c) strue; s(d) sfalse.
1.2. The simportance sof sthe snucleus sin sinheritance swas simplied sby sits sprominence
sin sfer- stilization. sThe sdiscovery sof schromosomes sinside sthe snucleus, stheir
sbehavior sduring scell sdivision, sand sthe sobservation sthat seach sspecies shas sa
scharacteristic schromosome snumber smade sit slikely sthat schromosomes swere sthe
scarriers sof sthe sgenes. sMicro- sscopic s studies s showed s that s DNA s and s proteins
s are s both s present s in s chromosomes, sbut swhereas snearly sall scells sof sa sgiven
sspecies scontain sa s constant samount sof sDNA, sthe samount sand skinds s of
sproteins sdiffer sgreatly sin sdifferent scell stypes.
