To the extent that the cumulative long-term obligation to provide pension benefits of the participating governments in a cost-sharing plan (their total pension liability) is larger than the value of the assets available in the pension planâs trust to pay pension benefits, there is a net pension liability.
One common homework and test question asks you to name the three types of RNA and list their functions. Here's the answer. Answer: There are actually several types of ribonucleic acid or RNA, but most RNA falls into one of three categories: 1  mRNA or Messenger RNA. 2  mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. 3  mRNA carries genetic information from the nucleus to the cytoplasm of a cell.
Although the functions of each type of RNA are different, one type of RNA is called messenger RNA, or simply mRNA. mRNA is created when the DNA recipe is copied in the first step of the central dogma. The information found in mRNA can be interpreted by using two other forms of RNA in the second step of the central dogma. mRNA is translated into protein at a cellular structure known as the ribosome. A second type of RNA helps form the structure of a ribosome. This type of RNA is called ribosomal RNA, or rRNA.
