Join us as we explore the fascinating world of cells! In this video, we’ll compare prokaryotic and eukaryotic cells, highlighting their key differences in structure, function, and complexity. From the simplicity of prokaryotes like bacteria to the intricate organization of eukaryotes such as plants...
Unlike prokaryotic cells, eukaryotic cells or bacteria are distinct types of organisms since their cells possess a nucleus. An additional outstanding...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask ...
Describe the functions of the cell membrane. What are the functions of a phospholipid? What kind of cells are the Schwann cells? Where are they located and what is their function? What is the role of epidermal cells in a plant? 1. What is the significance of a basement membrane? 2. Ho...
In contrast, plants harbour three distantly related homologues, which seem to have non-redundant functions either in meiosis or in somatic cells and are indispensable for viability. Moreover, plants possess a homologue of the subunit B of the archaebacterial topoisomerase VI, not present in other...
Animals are eukaryotic and usually multicellular (although see Myxozoa), which separates them from bacteria, archaea and most protists. They are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae,...
Endosymbiotic association between different bacteria around 1.6 – 2.0 billion years ago give rise to the first proto-eukaryotic cell, which gradually gives rise to eukaryotes. Ecology (Habitat) of Bacteria Bacteria are evolved to adapt and survive in any kind of ecological niches; from normal toex...
1). Phages are naturally-existing viruses that specifically kill bacteria, including MDR strains, while eukaryotic cells are not infected. Unlike antibiotics, phages are highly specific to the bacterial species, or even to the bacterial strain. Fig. 1: Transmission electron microscopy (TEM) image ...
Ribosomes are found in all prokaryotic and eukaryotic cells. The purpose of ribosomes is to synthesize proteins needed by the cell. They consist of a large subunit and a small subunit and are the sites of translation, or the conversion of mRNA informatio
In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process of cell division. ...
Thus, it is not surprising that as much as 1% of all prokaryotic and eukaryotic genes were estimated to encode helicases (Gorbalenya and Koonin, 1993). Download: Download full-size image Fig. 1. Schematic representation of NTP-dependent helicase activities. (A) Unwinding of a nucleic acid ...
