1) if onion cells are isotonic to 0.5% NaCl solution. What will be happened if the onion cells are placed in a 0.3% and 0.8% NaCl solutions? 2) In “Chardakov method for water potential measurement” experiment, you find that 0.30 M solution has not been changed by water loss or […]

A double-stranded fragment of viral DNA, one of whose strands is shown below, encodes two polypeptides called vir-1 and vir-2. Adding this double stranded DNA fragment to an in vitro transcription and translation system yields peptides of 10 residues (vir-1) and 5 residues (vir-2). 5′-AGATCGGATGCTCAACTATATGTGATTAACAGAGCCTGCGGCATAAACT-3′ (a) What are the nucleotide […]
