The genes that code for proteins and the genes for RNA products such as rRNA and tRNA constitute a surprisingly small portion of the genomes of most multicellular eukaryotes. The majority of most eukaryotic genomes consist of non-coding regions, sometimes described as "junk DNA." However, recent evidence shows that even this so-called "junk DNA" can play important roles. Which of the following is not a type of non-coding DNA?

Explanation:

1. DNA contain both coding ( exon) as well as non-coding (intron) sequences. The coding sequence codes for mature RNA and then translated  into protein.  

2.The coding sequence of DNA are  known as exons. DNA also contain non coding sequences, which are not transcribed into any RNA or then protein.  

3.These non-coding sequences are known as introns. These introns are removed during RNA splicing. The process of joining of exons and removal of introns is known as RNA splicing.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
