In evolution the studies can be made at molecular level. For example, the proteins present in the blood of man and ape are similar. The base sequence in nucleic acids and amino acids sequence in proteins of related organism is alike. These are the examples which are specifically referred to in

The base sequence for a nucleic acid segment is given as GAG AGG GGA CCA. From this, it can be concluded that it is a segment of a

Passage-III : The binary compounds of oxygen with other elements are called oxides. They are classified either depending upon their acid - base characteristics or on the basis of oxygen content. a ) Normal oxides : These oxides which contain oxygen atoms as permitted by the normal oxidation number, i.e., -2. Normal oxide may be acidic, basic, amphoteric or neutral. b) Polyoxides : The oxides which contain oxygen atoms different than those permitted by the normal oxidation number of -2. i) Peroxides : Two oxygen atoms are linked to each other and oxygen has -I oxidation number. They contain (O-O)^(2) unit. ii) Superoxides : These oxides contain (O-O)^(-1) units, i.e., each O-atom has oxidation number -1//2 . c ) Suboxides : These contain low content of oxygen than expected. d) Mixed oxides : These oxides are made of two simpler oxides. Which pair of species is referred to as suboxides?

Numerous forms of the periodic table have been devised from time to time. A modern version which is most convenient and widely used is the long or extended from of periodic table. The aufbau principle and the electronic configuration of atoms provide a theoretical foundation for the periodic classification. The horizontal rows are called periods. There are altogether seven periods. The first period consists of 2 elements. The subsequent periods consists of 8, 8,18, 18 and 32 elements respectively. The seventh period is incomplete and like the sixth period would have maximum of 32 elements. Elements having similar outer electronic configurations in their atoms are grouped in vertical columns. These are referred to as groups or families. According to the recommendations of IUPAC, the groups are numbered 1 to 18 replacing the older notation of groups 0, IA, IIA, ....VIIA, VIII, IB.....VIIB. Each successive period in the periodic table is associated with the filling up next higher principal energy level following aufbau sequence. The number of elements in each period is twice the number of atomic orbitals available in the energy level that is being filled. All the elements are classified into four blocks, i.e., s-block, p-block, d-block, and f-block depending on the type of atomic orbitals that are being filled with electrons. An element belongs to group 17 with atomic number is 17. What is the atomic number of the element belonging to same group and present in fifth period?

Proteins can also be classified based on their shapes and solubility in water. (i) Fibrous proteins are long and stringy, and are in soluble in water. Their primary role in structural materials of animal tissues. Eg : Collagens, Elastins, Keratins, and Fibrins. (ii) Globular proteins are compact and spherical and are soluble in water example enzymes, hormones, antibodies, transport proteins respiratory proteins. Which of the following belongs to collagen

When we concept that one mole of a substance contains the same numbers of elementary entities or one mole of any other substance, we don’t actually need to know what that number is. Sometimes however we will need to work with the actual number of elementary entities in a mole of substance. This number is called Avogadro.s number. N_(A)=6.022137xx10^(23) molecules The unit mol^(-1) which we read as per mole signifies that a collection of N_(A) molecular level entities is equivalent to one mole at the macroscopic level. For example a mole of carbon contains 6.02xx10^(23) atoms of C. A mole of oxygen gas contains 6.02xx10^(23) molecules of O_(2) . The number of atoms present in 8 g of ozone is

All titration which involves the direct titration of Iodine with a reducing agent are grouped under lodimetry. Iodimetry is employed to determine the strength of reducing agent such as sodium thio sulphate I_(2) + 2Na_(2)S_(2)O_(3) rarr 2I^(-)+S_(4)O_(6)^(-) If iodine is liberated as a result of chemical reaction involving oxidation of an idodide ion by a strong oxidizing agent in neutral or acidic medium the liberated iodine is then titrated with reducing agent. This titration is called lodometry. Todometry is used to estimate the strength of oxidizing agent. For example the estimation of Cu^(++) with thiosulphate. Cu^(+ +) +I^(-) Cu_(2)I_(2)+I_(2) , I_(2) +S_(2)O_(3)^(-) rarrS_(4)O_(6)^(-) +I^(-) Starch used as indicator near the end point which form blue colour complex with I_(3)^(-) . The blue colour disappears when In the reaction, 2CuSO_(4) +4KI rarr Cu_(2)I_(2) + 2K_(2)SO_(4)+I_2 the ratio of equivalent weight of CuSO_4 to its molecular weight is:

Which of the following refers to particularly stable arrangements of amino acid residues in a protein that rise to reoccuring patterns ?

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?
