WebExpert Answer. 17) Introns is also a part of DNA and do contain its complementary bases. So, the answer is (A). 18) Group, I &II introns are self- …. Which of the following is NOT … WebIntrons are actually noncoding DNA segments (in other words, they do not code for proteins), so splicing them out actually helps produce a functional protein rather than potentially disrupt protein function. However, this doesn't mean introns are useless either; in fact, they are actually very important for regulating gene expression.

WebNov 26, 2015 · 3 Answers. Sorted by: 6. While Ankur's answer is correct, it must be noted that not all non-coding RNAs are introns. An intron must be excised from an mRNA, which therefore means that any non-coding RNA that is not part of an mRNA cannot be an intron. For example, rRNA and tRNA are all examples of non-coding RNAs that are not … WebOct 1, 2024 · In certain cases, introns were shown to function as internal promoters (Furger et al., 2002, Morello et al., 2002, Samadder et al., 2008). This review focuses on introns that do not function as binding sites for transcription factors, and elevate expression only when present in the transcribed region. norm reeves richland hills

It is essential that all of the intron-encoded RNA sequences are completely and precisely removed from a pre-mRNA before protein synthesis so that the exon-encoded RNA … WebPrinciple of genetics mentions.
