Transcription
Before RNA can be used in protein synthesis, it must be made from DNA in a process called transcription. During transcription, segments of the DNA molecule serve as a template. The template is used to produce a complementary RNA strand -
RNA to cytoplasm
Since the DNA is transcribed into mRNA in the nucleus, and protein synthesis takes place in the cytoplasm, the mRNA has to exit the nucleus to the cytoplasm.mRNA will be "tagged" by proteins to give export signals to go to the nuclear pore complex where it's bound export proteins then attaches to export receptors and the whole complex is released into the cytoplasm. -
RNA attaching to ribosome
Ribosomal RNA, a molecular component of a ribosome, the cell's essential protein factory. ribosomal RNA does not make protein, It makes polypeptides that go to make up proteins. -
Translation
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA. an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated. Translation occurs in a structure called the ribosome, Then a transfer RNA (tRNA) molecule carrying the amino acid methionine binds to what is called the start codon of the mRNA sequence. -
Codon Cart
the code carried by RNA is made up of just four nucleotides represented by the letters: A, U, G, and C. The code is read in three-letter increments, called codons, one at a time. Each codon corresponds to an amino acid. there are more codons than amino acids so each amino acid has more that one codon -
Amino Acid Chains
Amino acids are the building blocks of all biological proteins. Amino acids link together via peptide bonds in a particular order as defined by genes. Genes are translated by RNA to amino acid chains; the length and order of the amino acid chain then dictates the three-dimensional structure of a polypeptide or protein.
