Without ribosome, a cell would not be able to produce proteins. <u>Ribosomes are the essential cell organelles that are found in both prokaryotic and eukaryotic organisms</u>. They play an important role in protein synthesis. As protein is an important biomolecule it can be used for several cellular processes.

Further Explanation:

Ribosomes are also called protein factories of the cell because it plays an essential role in the synthesis of protein. Both prokaryotic and eukaryotic cells contain ribosomes. 70s ribosome is found in the prokaryotic cell whereas 80s ribosome is present in the eukaryotic cell.

Ribosomes are composed of RNA molecules. They are found in the different locations of the cell. Some are located in the free-floating forms in the cytosol. The ribosomes found in the cytosol synthesize soluble proteins that are used inside the cell, whereas ribosomes found on the endoplasmic reticulum synthesizes secretory and membrane proteins. Ribosomes are the cluster of ribosomal RNA and protein.

During the process of protein synthesis, mRNA gets bind with the smaller ribosomal subunits in both prokaryotes and eukaryotes to form an initiation complex. It plays a vital role in the catalyzing the formation of the peptide bond between amino acids so that the amino acids are joined together to form a protein. The subunits of ribosomes are reassociated with others during the initiation of protein synthesis. Transfer RNA gets binds with larger subunits of ribosomes.

Hence, each mRNA molecule is translated by several ribosomes during protein synthesis in a direction; such as a reading of mRNA can be done from 5’3’ end. And the polypeptides are synthesized from the N-terminus of amino acids to C-terminus of amino acids. A complete structure of mRNA-poly-ribosome is called polysomes.

Which has a greater biotic potential- humans or mice? Why?

Ganezh [65]

Nice because : Biotic potential is the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.

Each daughter cell resulting from mitotic cell division has exactly the same genetic composition. Select one: True False

sveta [45]

Answer: True

Explanation: The importance of mitotic cell division is to produce two daughter cells that are genetically identical. The genetic materials of the parent cell are arranged and moved towards the two spindle poles with the help of the spindles so that there will be an even distribution of the parent cell's genetic materials between the resulting two daughter cells.

What are the 3 different shapes, or structures, or carbon base molecules?

ddd [48]

Answer:

Carbon based molecules have 3 main structures which are

straight chain

branched chains

rings

Explanation:

The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.

Which region in the United States has the fewest thunderstorms per year?

Serga [27]

Answer:

Pacific Northwest

Explanation:

In the United States, the Pacific Northwest is the region that receives the least thunderstorm in a year. This is because of the location of the region. The region consists of states like Washington, California, Alaska, Hawaii, and Oregon. This region has few thunderstorms due to the nature of the region. The coldness of the pacific ocean means that there is more colder air on the earth. This suppressed the hot air. Thus, conventional rainfall; with thunder is less common. The other factor is the dryness of the region. The dry region has a lower humidity. This lesson the chance of charges air between the two fronts.
