There are some exceptional free living organisms from the tree of life that lack rRNA O True False

I'm lederberg experiment ecology colonies grow in a sense of bacteriophage when transferred by replica plotting onto 2 plates with bacteriophage they observed some colonies resistant to bacteria phage what did the observation allow them to conclude

5. Molecular Evidence. Cytochrome c is a protein located in the mitochondria of cells involved with cellular respiration. Compare each organism's Cytochrome CDNA sequences with the ancestor cell and each other. Circle or highlight the differences (mutations) present in the cytochrome CDNA sequences from ancestor cell.

Will Beta-lactam antibiotics disrupt cell wall formation in Domain Archaea? • A. No as Archaea do not have a 1,4 glycosidic bond • B. No as Archaea do not have a D-ala D-ala in their peptide side-chain • C. Yes, they will target the 1,3 glycosidic bond D. No as Archaea do not contain NAM in their backbone O E. Yes, they inhibit peptide side-chain cross-linking
