Answer:
Traditionally, all prokaryotic cells were called bacteria and were classified in the prokaryotic kingdom Monera. ... One fundamental difference is that bacterial cells lack intracellular organelles, such as mitochondria, chloroplasts, and a nucleus, which are present in both animal cells and plant cells.
C) DNA is made of 4 types of nucleotides
Not all organisms have 46 chromosomes (23 homologous pairs). Not all organisms have nuclei (e.g. bacteria do not have nucleus)
First, crossing-over and the subsequent rearrangement of alleles on homologous chromosomes leads to gametes with a new mix of genetic material. Second, when the gametes fuse, new combinations of alleles result.
