Question

the statement is true or false and then explain why.

In a comparison between the DNAs os related organisms such as humans and mice, identifying the conserved DNA sequences facilitates the search for functionally important regions.

Answer 1

The above statement is TRUE.

The system for controlling genome activity in the two species are very alike, which have been preserved through time to time.

They have been detected certain difference in the DNA and different patterns of gene expression that are not shared.

The researchers have compared various processes involved in gene expression, such as gene transcription and chromatin modifications and also repeated this in different tissue and cell type from both human and mice.

Discovered that human and mice transcriptome cobtains both preserved and divergent elements.

For example- TATA the repetitive regions and Homeoboxes which involved in regulating embryonic development in a wide range of species.

CONSERVED SEQUENCES

Conserved sequences are also called as biological significance.

In evolutionary biology and genetics, the conserved sequences of DNA or RNA or amino acids that occur in different ir same species over generations.

The translation and transcription related sequences, whichare found conserved in the genome at multiple places.

Certain RNA components in ribosomes are found to be highly conserved over various species.
