2.Cytoplasm: It consists of the jelly-like cytosol present inside the cell, along with the cellular structures suspended in it.3.DNA or RNA: It is the genetic material of the cell. The majority of prokaryotic DNA is found in the nucleoid and consists of a single large loop known as a ...
Many researchers today believe that the first cells or unicellularprokaryoticorganisms did not arise from any precursor cell. They were formed from a biological force still unknown to the human race today. Though highly disputed, this theory still violates the cell theory. Mitochondria and chloroplasts...
for example, contains thousands of ribosomes, some of which are free in the cell, and some of which are stuck onto a cell structure called the endoplasmic reticulum. It is not just the components of a prokaryotic ribosome that is necessary for its function but the shape of the ribosome...
In a prokaryotic cell, DNA is found where? Which best describes the first organisms on Earth: a. simple prokaryotes b. multicellular prokaryotes c. simple eukaryotes d. archaea with simple DNA Describe two applications of transgenic organisms ...
Because the carboxylic acid group on the amino acid in the enzyme's active site must be in its protonated state, meaning bonded to a hydrogen atom, pepsin works best at pH $1.8$ . The carboxylic acid group is protonated at low pH, allowing it to catalyse the chemical reaction of ...
A student nurse practitioner asks her preceptor about the origins of different tissues, and their cellular origins during the process of development. Which of the following statements by the preceptor best describes the process of cell differen...
Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. The pH of distilled water is $7$ when it is in ...
Which of the following best describes osmosis? A) movement of water into a solute. B) diffusion of water from a greater to a lesser water concentration. C) diffusion of water from a greater to a lesser water concentration across a selectively permeable me ...
All of the following describes organisms in the domains Bacteria and or Archaea except: O Cell wall O Single-celled O Prokaryotic O Multicellular What type of organelles do prokaryotes have, if any? Name all the kingdoms that contain prokaryotic cells. ...
Which of the following describes transcription factors? a) Control of gene expression b) Regulation of DNA duplication c) ATP into cAMP d) Synthesis of glycogen Describe some of the general ways in which (specific) transcription factors are regulated and how they, in turn, can regulate ...
