The ribosome of the bacterium e. coli includes the ribosomal protein l4 (rpl4). the rpl4 gene carries the instructions for making rpl4 protein. which of the following arguments provides support for the claim that e. coli has a common ancestor with all other organisms?
rough er is called rough because it has ribosomes attached to its surface. the double membranes of smooth and rough er form sacs called cisternae. protein molecules are synthesized and collected in the cisternal space/lumen. when enough proteins have been synthesized, they collect and are pinched off in vesicles.
the answer is a-paleontologist
hope this : )
c. codominantexplanation; codominance is a phenomenon where alleles of a particular gene pair in a heterozygous are fully expressed. the results is a an offspring with a phenotypes which is neither recessive nor dominant. an example of codominance is the abo blood group system. an individual with ab blood, which means that both the a allele and the b allele are equally expressed.
