Serving a Three-Day Notice to Pay or Vacate. A landlord has several options when giving a tenant a three-day notice to pay or vacate: 1  The landlord, or landlordâs agent, can personally give the notice directly to the tenant.  The landlord can mail a copy of the notice to the tenant through registered or certified mail.
A nucleic acid that contains the genetic instructions used in the development and functioning of all modern living organisms. DNA's genes are expressed, or manifested, through the proteins that its nucleotides produce with the help of RNA. Messenger RNA (mRNA) transcribes genetic information from the DNA found in a cell 's nucleus, and then carries this information to the cell's cytoplasm and ribosome. 2  Transfer RNA (tRNA) is found in a cell's cytoplasm and is closely related to mRNA as its helper.
RNA is very similar to DNA, but differs in a few important structural details: RNA is single stranded, while DNA is double stranded. Also, RNA nucleotides contain ribose sugars while DNA contains deoxyribose and RNA uses predominantly uracil instead of thymine present in DNA. RNA is transcribed from DNA by enzymes called RNA polymerases and further processed by other enzymes. RNA serves as the template for translation of genes into proteins, transferring amino acids to the ribosome to form proteins, and also translating the transcript into proteins.
