What kind of a molecule is a microRNA?
microRNA is a "non-coding RNA" molecule. This means that it does not translate into a protein. These are sometimes also called "non-messenger" RNA molecules.
CGT base triplet on DNA is copied into mRNA as?
microRNA
Why are women healthier than men?
Women are not necessarily healthier than men. Women on average do live 5-10 years longer than men because women have the XX chromosomes and men have the XY chromosomes. This matters because the X chromosome contains microRNA (small strands of ribonucleic acid). MicroRNA tells our genes what or what not to do. MicroRNA also plays a role in our body's immune system which can help ward off infections and cancer. A lot of this microRNA is contained in the X chromosome, basically doubling women's chances.
What are examples of microRNA?
microRNAs are small single stranded RNA molecules in the cytoplasm of cells. They are found in plants as well as animals.
Which type of RNA makes protein?
1. mRNA - provides 'template' for protein 2. tRNA - carries amino acids 3. microRNA/siRNA - regulate protein production
What are the bases on the mRNA strands are called?
A 3-base sequence of nitrogen bases on a molecule of mRNA is called a codon.
What many different RNA exist?
4 different RNAS exist. There is mRNA, tRNA, rRNA, and as of this past year microRNA. Although these are the only known ones there may be numerous more.
How mi RNA differ from si RNA?
MicroRNA are usually 22 nucleotides long, and are post-transcriptional regulators. Small interfering RNAs are usually 20-25 nucleotides long, and are mostly involved with the disruption of gene expression. siRNA is also double-stranded.
How does the process of RNA interference work?
Certain small RNA molecules fold into loops. The Dicer enzyme cuts them into microRNA (miRNA). The strands then separate. An miRNA piece attaches to a cluster of proteins to form a silencing complex. The silencing complex binds to and destroys an mRNA molecule that contains a base sequence complementary to the miRNA. In this way, it blocks gene expression.
How do you write 'works' in French?
"works" as in "(road)works" is "travaux" (masc.) "works" as in "she works" (the verb) is "travaille".
