Q:l Definel thel wobblel hypothesisl andl explainl whyl itl isl importantl forl thel
degeneracyl inl coding.
Answer:
thel wobblel hypothesisl allowsl forl flexiblel base-pairingl rulesl inl thel thirdl
positionl ofl al codon.l Inl severall cases,l thel firstl twol basesl arel thel samel forl
al specificl aminol acid,l andl thel thirdl positionl canl bel anyl ofl thel fourl bases.l
Becausel therel arel onlyl 40l tRNAsl tol encodel aminol acidsl forl 60+l codons,l
thel wobblel hypothesisl allowsl forl somel degeneracyl inl thel coding,l wherebyl
onel tRNAl canl recognizel severall codonsl tol encodel onel aminol acid.
Q:l Thel (1)_____l elementl isl al cis-actingl elementl thatl isl locatedl (2)____l
froml thel sitel ofl transcriptionl initiation
Answer:
Pribnow;l upstream
Q:l Truel orl False:
Al silencerl elementl isl alwaysl locatedl closel tol thel genel thatl itl affects,l butl
anl enhancerl elementl canl bel farl away.
, Answer:
False
Q:l Whatl isl thel enzymel thatl contributesl tol thel growthl ofl al nucleotidel
chainl andl alsol helpsl inl thel proofreadingl process
Answer:
Polymerasel (RNAl orl DNA)
Q:l Inl thel processl ofl RNAl splicingl ___l arel removedl froml thel pre-mRNAl
andl ____l arel rejoinedl tol makel al maturel mRNA.
Answer:
introns;l exons
Q:l Howl doesl alternativel splicingl enhancel thel diversityl ofl thel geneticl
code?
Answer:
Alternativel splicingl meansl thatl differentl combinationsl ofl intronsl canl bel
splicedl outl ofl al singlel mRNAl producingl multiplel differentl maturel mRNAs.l
Therefore,l severall proteinsl canl bel encodedl froml thel samel nucleotidel chain.
