The process of synthesis of mRNA according to the nucleotide sequence present on the DNA is called transcription. 1

The process of bringing tRNA possessing anticodon, that is complementary to the codon on mRNA for protein synthes is called translation. 2

The process of movement of the ribosome from one end of mRNA to the other end, by the distance of one triplet codon is called translation. 2

A sudden and drastic change that occurs in genetic material is called mutation. 2

Degenerated or underdeveloped useless organs of organisms are called as vestigial organs. 5

Large number of organisms get buried due to disasters like flood, earthquake, volcano, etc. Remnants and impressions of such organisms remain preserved underground. These are called as fossils. 5
