In an analogy between a factory and a cell, tRNA is like the 'delivery truck' that carries the necessary parts (amino acids) to the assembly line (ribosomes). It plays a crucial role in protein synthesis by translating the instructions from DNA and mRNA into a physical protein structure.
In the analogy between a factory and a cell, tRNA might be considered the 'delivery truck' that carries the necessary parts (amino acids) to the assembly line (ribosomes). DNA provides the instructions (genes), mRNA conveys these instructions to the ribosomes, and then tRNA transports the correct amino acids to the ribosomes based on the information in the mRNA. Each tRNA molecule contains an anticodon that matches a specific codon (set of three nucleotides) on the mRNA, allowing it to carry and add the corresponding amino acid to the growing polypeptide chain. This process of translation 'reads' the language of mRNA and translates it into the language of proteins. In other words, tRNA plays an essential role in the synthesis of proteins within a cell, facilitating the transfer of information from DNA and mRNA to a physical, functional protein structure.

The North Atlantic Treaty Organization (NATO) is an international military alliance that has 28 member states, including Europe, America, Britain and France as its member. NATO was established in 1949 and has its headquarters in Brussels, Belgium and Haren. The main purpose of NATO is to keep its members safe especially Europe by providing defence in response to an attack by any external party.
uncontrolled cell divosion is the answer
solid and liquid
solid
Answer:
gas
Explanation:
In gas there are weak attraction forces present between the particles.
Properties of gases:
Molecule of gases randomly move everywhere and occupy all available space.
Gases don't have definite volume and shape and take the shape and volume of container in which it present.
Their densities are very low as compared to the liquid and solids.
Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.
The very weak inter molecular forces are present between gas molecules.
Properties of Liquid:
Liquid have definite volume but don,t have definite shape.
Their densities are high as compared to the gases but low as compared to the solids.
In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
