WebRNA molecules are produced in the nucleus of human cells from DNA by a process called transcription, but they are found in the cytoplasm too. DNA is present only in the nucleus of the cell. Three Primary Types of RNA. Ribosomal RNA (rRNA), transfer RNA (tRNA), and messenger RNA (mRNA) are the main types of RNA. Web31 aug. 2024 · Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein. These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic.
