y gUles for reproduction. Cell division cnables DluQlng organisms to develop from a single cell. The cells division also repairs, and replaces cells that die. When bacteria are placed in a medium that provides all of the nutrients that an necessary for their growth, the population exhibits four stages of growth that are representative of a typical bacterial growth curve. In the lag phase, the cells are metabolically active and increase only in cell size. In log phase, in which cell numbers increase in a logarithmic fashion and each cell generatio occurs in the same time interval. In the log phase continues until nutrients are depleted. In the stationa phase, which the size of a population of bacteria remains constant even though some cells.continue to divide and others begin to die. 5. List the differences between a bacterial chromosome/genome a nd eukaryote chromosomes and genomes? In prokaryotes such as bacteria possess a single chromosome composed of double-stranded DNA in a loop and I believe that the DNA is located in the nucleoid of the cell and is not associated with protein. A chromosome is a singular piece of DNA. Sister chromatids are identical copies of a chromosome. Genome is a full set of chromosomes. Chromosomes consist of chromatin in which the chromatin makes up chromosomes and the chromatin is the complex of DNA. In other words, genome is the full set of all chromosomes in an organism and Chromosome is coiled up DNA. I believe that the only difference is that they are much thinner and longer. Bacterial chromosome is linear in shapeExplanation / Answer
Prokaryotes have single circular chromosome where as eukaryotes have many linear chromosomes. Mostly prokaryotes contain one copy of each gene where as mostly eukaryotes have two copy of each gene. Prokaryotes have their DNA condensed into nucleoids via some architectural proteins where as eukaryotic chromosomes are condensed into nucleus via Histone proteins. Prokaryotes have plasmid to encode nonessential genes whereas eukaryotes don't have plasmid DNA. Prokaryotes have no introns in their DNA where as eukaryotic chromosomes have large amount of introns in their chromosomes.
