Question

Why is the outdated term "junk dna" a misnomer for noncoding regions of the human genome? Why is the outdated term "junk dna" a misnomer for noncoding regions of the human genome? The conservation of "junk dna" sequences in diverse genomes suggests that they have important functions. So-called "junk dna" is transcribed into rrna and trna. Most areas of the human genome once called "junk dna" actually do code for protein?

Answer 1

Dna is In cellls

Step-by-step explanation:

Answer 2

Answer;

-The conservation of "junk DNA" sequences in diverse genomes suggests that they have important functions.

Explanation;

-The term junk DNA refers to regions of DNA that are noncoding. DNA contains instructions (coding) that are used to create proteins in the cell. However, the amount of DNA contained inside each cell is vast and not all of the genetic sequences present within a DNA molecule actually code for a protein.

-Some of this noncoding DNA is used to produce non-coding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA. However, other DNA regions are not transcribed into proteins, nor are they used to produce RNA molecules and their function is unknown.
