QUESTION 24 Which of the following clusters of terms accurately describes DNA as it is generally viewed to exist in prokaryotes and eukaryotes? double-stranded, parallel, (A + T)(C+G)= variable, (A+G)(C+T)=1.0 double-stranded, antiparallel, (A + T)/(C+G)= variable, (A + G)(C+T)= 1.0 double-stranded, antiparallel, (A + T)(C+G)= variable, (A + G)(C+T)= variable double-stranded, parallel, (A + T)/(C+G) = 1.0, (A+G)(C+T)= 1.0 single-stranded, antiparallel, (A+ T)(C+G) = 1.0. (A+G)(C+T)=1.0 QUESTION 25 on anzume which has the property of: 3:18 PM
QUESTION 38 During bacterial translation initiation, the mRNA binds to the ribosome large subunit is oriented by its Shine-Delgamo sequence through base-pairing with the RNA component of the ribosome subunit requires helicase activity for binding to the ribosomal subunit is oriented so that the AUG start codon is in the A site only binds f-Met tRNA after the entire ribosome has been assembled QUESTION 39 When examining the genetic code, it is apparent that: more than one amino acid matches a particular codon the code is ambiguous in that the same codon can code for two or more amino acids since there are only 20 amino acids and 64 codons, this means that 44 codons do not enoode any amino acids more than one codon can code for a particular amino acid AUG is a terminating codon 1.667 points 1467 Sex Mo PM
