Science Define :

The ribosome keeps on moving from one end of mRNA to other end by the distance of one triplet codon. This is called Translocation.

As per the message on mRNA, amino acids are supplied by the tRNA. For this purpose, tRNA has 'anticodon' having complementary sequence to the codon on mRNA. This is called Translation.

The code for each amino acid consists of three nucleotides. It is called as Triplet codon.

The process of RNA synthesis is called as Transcription.

Information about protein synthesis is stored in the DNA and synthesis of appropriate proteins as per requirement is necessary for body. These proteins are synthesized by DNA through RNA. This is called Central Dogma.

The living organism can transfer the characters which it has acquired, to the next generation. This is called Ancestry of acquired characters.

The time passed since the death of a plant or animal can be calculated by measuring the radioactivity of C-14 and ratio of C-14 to C-12 present in their body. This is carbon dating method.

Degenerated ог underdeveloped useless organs of organisms are called as vestigial organs.

Formation of new species due to changes in specific characters of several generations of liv- ing organisms as a response to natural selection is called as evolution.

Heredity is the transfer of biological characters from one generation to another via genes.
