Which of the following is present in maximum amount in atmosphere?
Occurrence of higher number of endemic species in South America and Australia is due to
DNA is the genetic material that carries genetic information regarding corresponding amino acid sequence of proteins. Accumulation of differences in their genomes parallels divergent evolution of species, while conservation of DNA sequences leads to convergent evolution. The more recent the divergence of two species from a common ancestor, the more preserved sequences of DNA and amino acids should be. Synthesis of RNA using the DNA template strand is referred to as transcription. The primary transcript, the original product of transcription, is then processed into different types of RNA. Thus, sequence of DNA strand determines the nucleotide sequence of RNA. Therefore, molecular systematics studies DNA sequence to decipher the phylogenetic relationship between different organisms.
