Wobble hypothesis indicates that:a. fatty acids are degraded 2 carbons at a time.O b. 16S-ribosomal RNA recognizes Shine-Dalgarnosequence of the mRNA and thus initiates proteinsynthesis.O C.DNA replication is semi-conservative.d.the 5'base of anticodons may recognize 1, 2 or 3bases in the codons and thus only 31 differenttRNA molecules can recognize 61 codons.e. DNA replication proceeds bidirectionally.

As per the central dogma of molecular biology, genetic information is stored in the DNA. The genetic…
