A.the unlikelihood that a folded RNA template could directly interact with hydrophobic amino acids B.the unlikelihood that a folded RNA template could discriminate between amino acids of a similar size C.the unlikelihood that a folded RNA template could form a cavity specific enough to fit only one given amino acid D.the unlikelihood that a folded RNA template could directly interact with hydrophilic amino acids
© 2014 Pearson Education, Inc. The hypothesis that the genetic code consisted of groups of three nucleotides rather than groups of two nucleotides supports which of the following conclusions? A.Some codons must code for multiple amino acids. B.Every amino acid has at least one unique corresponding codon. C.Every amino acid has only one corresponding codon. D.All codons encode an amino acid.
© 2014 Pearson Education, Inc. Which one of the following statements about the processes of transcription and translation is FALSE? A.The synthesis of mRNA occurs in the 5 to 3 direction. B.The synthesis of proteins occurs in the 5 to 3 direction. C.The DNA template is read in the 3 to 5 direction during mRNA synthesis. D.A transcribed mRNA and its non-template DNA strand are both oriented the same way with respect to the template DNA strand.

Objective: What are the steps involved in protein synthesis?
Making of Proteins. DNA Replication DNA molecule produces two new complementary strands. Each strand of the double helix of DNA serves as a template for.
Protein Synthesis Occurs in 2 steps – Step 1: Transcription Taking DNA and transcribing it into RNA – Step 2: Translation Taking RNA and translating it.
