Some simple eukaryotic genes can be transcribed and translated by prokaryotes like E. coli. However, some eukaryotic genes cannot be expressed by prokaryotes. Which of the following might be a reason for this failure? A. Prokaryotes are not able to cut out the introns nor are they able to O splice the exons together from the eukaryotic gene. B. the prokaryotic genetic code is sometimes different from eukaryotic code. C. Eukaryotic genes often have unique nucleotide bases which are not...

8. Which of the statements about the organization of complex multicellular organisms is false? Only some cells are in direct contact with the environment. Exterior cells receive environmental signals directly, whereas interior cells receive environmental signals indirectly Exterior cells are highly differentiated, whereas interior cells are not differentiated. Interior cells cannot grow as fast as exterior cells without mechanisms to transfer nutrients between cells. Signals transferred from exterior cells to interior cells can activate or repress gene expression in the...
