Question

Difference between conserved and nonconserved dna sequences

Answer 1

Conserved sequence:

A base sequence in a DNA molecule (or an amino acid sequence in a protein) that has remained essentially unchanged, and so has been conserved, throughout evolution

NON CONSERVED SEQUENCE:

In order to identify non conserved residues in naturally occurring PHBH enzymes, the DDBJ database was searched; 92 PHBH sequences were found, including of 36 sequences from α-proteobacteria, 15 from β-proteobacteria, 31 from γ-proteobacteria, 8 from actinomycetes, 1 from acidobacteria and 1 from a Bacillus strain. The longest sequence contained 410 residues and the shortest sequence contained 389 residues. Most α-proteobacterial PHBH enzymes comprised 389–393 residues, while β-proteobacteria enzymes generally consisted of 407 or 410 residues and most γ-proteobacteria enzymes contained 394 or 395 residues
