Web6.15: Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. WebA student uses a microscope to observe a cell that has a cell wall, a plasma membrane, and circular DNA. What kind of cell is this student observing? Prokaryotic DNA is circular, while eukaryotic DNA is helical. Which statement best describes the difference between prokaryotes and eukaryotes with regard to DNA? colour starts with t

23.1B: Characteristics of Eukaryotic DNA - Biology …

WebIn eukaryotes, cytoplasm specifically means the region outside the nucleus but inside the plasma membrane. DNA is the genetic material of the cell. Ribosomes are molecular machines that synthesize proteins. Despite these similarities, prokaryotes and eukaryotes differ in a number of important ways. WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. WebJan 26, 2024 · Prokaryotic cells are much smaller than eukaryotic cells because they don’t have to fit as many organelles inside. Prokaryotes typically measure 0.2 – 2.0µm in diameter, whereas eukaryotic cells are 1 – 100 µm in diameter. Types of Organisms There are only two types of prokaryotic organisms on Earth, and those are bacteria and archaea. dr terri wilson
