The following features occur during protein synthesis: (a) Movement of mRNA from the nucleus into the cytoplasm, where it binds to the ribosomes (b) Formation of tRNA-amino acid complex (c) Transcription of specific segments of DNA into mRNA molecules in the nucleus (d) Binding of N-terminal amino acid, methionine tRNA to the 'P' site of the ribosome. The tRNA anticodon 'pairs with AUG on mRNA' (e) Formation of peptide bond between first and second amino acids at the A site (f) Release of the complete polypeptide chain from mRNA and the ribosomes (g) Migration of dipeptide to form a tripeptide and then a polypeptide The correct order of events is:

Following are the stages in the cellular synthesis of a protein. I. Movement of mRNA from the nucleus to cytoplasm. II. Linking of adjacent amino acid molecules. III. Transcription of mRNA from a DNA template. IV. Formation of the polypeptide chain. V. Attachment of the mRNA strand to a ribosome. In which order do these stages take place?

Essential amino acids are those which our body and, therefore, we taken them from diet . These are usually seven in number and are .

One test tube contains some acid and another test tube contains an equal quantity of water. To prepare a solution, 20 grams of the acid is poured into the second test tube. Then, two-thirds of the so-formed solution is poured from the second tube into the first. If the fluid in first test tube is four times that in the second, what quantity of water was taken initially? (a) 40 grams (b) 60 grams (c) 80 grams (d) 100 grams

Proteins are high molecular mass complex biomolecules of amino acids. The important proteins required for our body are enzymes, hormones, antibodies, transport proteins, structural proteins, contractile proteins etc. Except for glycine, all alpha -amino acids have chiral carbon atom and have L-configuration. The amino acids exists as dipolar ion called zwitter ion, in which a proton goes from the carboxyl group to the amino group. A large number of alpha -amino acids are joined by peptide bonds forming polypeptides. The peptides having very large molecular mass (more than 10,000) are called proteins. The structure of proteins is described as primary structure giving sequence of linking of amino acids, secondary structure giving manner in which polypeptide chains are arranged and folded, tertiary structure giving folding, coiling or bonding polypeptide chains producing three dimensional structures and quaternary structure giving arrangement of sub-units in an aggregate protein meolecule. Which of the following alpha -amino acid does not form optical isomers?
