In biology, what is a cell membrane and its functions? What is an organism called when it is made of only one cell? What are all the secretory cells in the body? What do plant cells have that animal cells do not
What are the degradations involved in cell division? What are the cell organelles that contain their own DNA and ribosomes? In what ways do prokaryotic and eukaryotic cell division differ? What are the branches of cell biology? Which of the following is a cellular characteristic of all eu...
_ which have cells that include a bare minimum of essential components: genetic material (i.e., DNA), a cell membrane to keep the whole thing together, cytoplasm (the gel-like matrix forming the majority of the cell's mass) and ribosomes, which manufacture proteins....
The Earth is home to a wide variety of living beings. It is estimated that about 8.7 million species of living beings are currently on the Earth of which 1.2 million species are known to us. These biotic components have total biomass of about 545.8 gigatons, of which 12.8 % is bacterial ...
Proteins are known to perform an astonishing array of functions thanks to their ability to cooperate and modulate each other’s properties. Inside cells, proteins can assemble into large multi-subunit complexes to carry out complex cellular functions. The correct assembly and maintenance of the functi...
· In the cytoplasmic side of the endoplasmic reticulum, proteins are first produced/synthesized by ribosomes (ribosomes located on the surface of rough endoplasmic reticulum). Once they are produced, these proteins move into the lumen of the endoplasmic reticulum where a given set of enzymes ...
The mechanism of memory remains one of the great unsolved problems of biology. Grappling with the question more than a hundred years ago, the German zoologist Richard Semon formulated the concept of the engram, lasting connections in the brain that resul
Prokaryotic cells have the same four components found in all cells in the natural world: DNA, a cell membrane, cytoplasm and ribosomes. Their cytoplasm contains all of the enzymes needed for glycolysis, but the absence of mitochondria and chloroplasts means that glycolysis is really the only meta...
the COVID-19 virus genome is then released inside the host cell and the virus replicates its polyproteins 1a and 1ab that are coded byopen reading framegenes (ORF-1aandORF-1b)[14]. This helps to hijack the host’s cellular machinery and take control of the host ribosomes, for their...
Which organism does not obey the ''Cell Theory'' in biology? What cellular structure assembles amino acids into polypeptides? A) Golgi bodies B) mitochondria C) ribosomes D) centrioles E) lysosomes What are all the secretory cells in the body? What does the mitochondria do in a cell?
