Proteins have primary structure. If you are given a method to know which amino acid is at either of the two termini (ends) of a protein, can you connect this information to purity or homogeneity of a protein?

When proteins having amino acids with some non protein part called prosthetic group they are called as

Aminoacids, as the name suggests, have both an amino group and a carboxyl group in their structure. In addition, all naturally occurring aminoacids (those which are found in proteins) are called L aminoacids. From this, can you guess from which compound can the simplest aminoacid be made?

Can you describe what happens when milk is converted into curd or yoghurt, from your understanding of proteins.

Enzymes are proteins. Proteins are long chains of aminoacids linked to each other by peptide bonds. Amino acids have many functional groups in their structure. These functional groups are, many of themat least, ionisable. As they are weak acids and bases in chemical nature, this ionization is influenced by pH of the solution. For many enzymes, activity isinfluenced by surrounding pH. This is depicted in the curve below, explain briefly.

Read the paragraph and answer the questions given below: With the help of RNA, the genes present in the form of DNA participate in the functioning of cell and thereby control the structure and functioning of the body. Information about protein synthesis is stored in the DNA and synthesis of appropriate proteins as per synthesized by DNA through the RNA. This is called 'Central Dogma'. mRNA is produced as per the sequence of nucleotides on DNA. Only one of the two strands of DNA is used in this process. The seqience of nucleotides in mRNA being produced is always complementary to the DNA strand used for synthesis. Besides, there is uracil in RNA instead of thymine of DNA. This is process of RNA synthesis is called 'transcription'. How is a specific protein synthesised in the cell?

Read the paragraph and answer the questions given below: With the help of RNA, the genes present in the form of DNA particioate in the functioning of cell and thereby control the structure and functioning of the body. Information about protein synthesis is stored in the DNA and synthesis of appropriate proteins as per synthesized by DNA through rthe RNA.

Paragraph based Questions : Read the paragraph and answer the, questions given below: Sulphuric acid is present in the acid rain and materials coming out of mines . You know that erosion of metals present in statues, bridges and buildings occurs due to it. Sulphuric acid is a source of energy for some species of bacteria like Acidophilum spp. and Acidobacillus ferrooxidans Hence. these bacteria can control the soil pollution occurring due to acid rain water soluble salts of uranium are present in the wastes produced during electroplating and in effluent released in the environment from the atomic energy Plant. Geobacter convert these salts of uranium into insoluble salts and thereby prevent those salts from mixing with groundwater sources. Sulphuric acid is the source of energy for which bacteria?
