Answer #1

1. The given statement is FALSE
The central dogma of life:
DNA ---> RNA ---> Protein
RNA is produced from DNA by transcription.
The mRNA is used as the template for the polypeptide synthesis by translation machinery. The primary RNA undergoes post-transcriptional modifications to produce mature mRNA. Only the mature mRNA codes for proteins.

2. The given statement is TRUE
The Peptidyl transferase activity located in the large ribosomal subunit is responsible for the peptide bond formation between two amino acids. It is a ribozyme.

1. Select all the of the statements below that apply to both eukaryotic and bacterial gene expression? Bacteria and eukaryotes can have 70S ribosomes. Bacteria and eukarytoes may have genes organized and regulated within operons. Bacteria and eukaryotes have 70S ribosomes in their cytoplasm. Initiation of translation in bacteria and eukaryotes occurs when the ribosomal subunit binds to the 5' guanine cap. Bacterial and eukaryotic mRNA is modified prior to translation.
