Coacervates were large colloidal aggregates named by 1. Haldane 2. Oparin 3. Preyer 4. Bondi

The important gas which was absent during the origin of life on Earth:

In some chemical reactions, it is found that a large number of colliding molecules have energy more than threshold energy value, yet the reactions are quite slow. Explain.

Sequence of substances appearing during the origin of life would have been

After the addition of the last amino acid to a growing polypeptide chain during the process of protein synthesis, one of the termination codons reaches the appropriate site on the ribosomal surface and then the following envents take place (i) Release of t-RNA molecule from the ribosome. (ii) Dislodging of polypeptide chain from the t-RNA (iii) Dissociation of ribosomes into large and small subunits. The correct sequence of these events:

Cells of certain species of animals have six pairs of chromosomes. How many molecules of DNA will remain in the nucleus of these animals during G_(2) -phase

DNA replication takes place in Or DNA molecule of each chromosome become double in Or DNA and histone proteins are synthesized during the following phase of cell cycle.
