What is a ribosome made of?
A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
What is the structure of a ribosome?
A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits. The large subunit sits on top of the small subunit, with an RNA template sandwiched between the two.
What is function of ribosome?
Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).
How does a ribosome work?
During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
Which of the following is a function of ribosome?
(i) It helps in manufacture of protein molecules. (ii) It helps in manufacture of enzymes. (iii) It helps in manufacture of hormones. (iv) It helps in manufacture of starch molecules.
What is the function of a ribosome in protein synthesis?
The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.
What is the process of ribosomes making proteins?
What is the function of the ribosome in protein synthesis?
Where do ribosomes function?
Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum. Their main function is to convert genetic code into an amino acid sequence and to build protein polymers from amino acid monomers.
What are the function of ribosome?
What is an important function of ribosome?
Which process do ribosomes perform?
The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids. The ribosome translates each codon, or set of three nucleotides, of the mRNA template and matches it with the appropriate amino acid in a process called translation.
What role do ribosomes play in protein synthesis?
How does a Soxhlet extractor work?
Soxhlet extractor needs the desired compound to be soluble in the solvent at a high temperature. One cycle of the soxhlet extraction method involves extraction following the evaporation of the solvent.
How do you extract a Soxhlet sample?
Apparatus Used For Soxhlet Extraction Method PROCEDURE: First of all, rinse all the glass apparatus by petroleum ether and dry it in the oven at 102°c and after removing it keep in the desiccator. Weigh 5 gram of grounded and dried sample and place it in the thimble.
How many times can we use the Soxhlet extraction method?
One cycle of the soxhlet extraction method involves extraction following the evaporation of the solvent. And theoretically, we can perform this cycle as many times as we want to get the maximum yield of the desired compound.
What are the disadvantages of Soxhlet extraction?
The most significant drawbacks of Soxhlet extraction are: long extraction times (e.g. up to 24–48 h), large amount of solvent usage (300–500 mL per sample), and the need for evaporation after sample extraction.
