A DNA subunit composed of a phosphate group, a five-carbon sugar, and a nitrogen-containing base is called a(n) _____. RNA is synthesized from DNA, and enters the ribosome where protein translation and synthesis occurs. Protein synthesis is the process by which new proteins are generated. When the process occur in cells, it is called protein biosynthesis. Protein biosynthesis is the process whereby biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. Protein synthesis is accomplished through a process called translation. In translation, RNA and ribosomes work together to produce proteins. Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide. TRANSCRIPTION. DNA carries the genetic instructions , or code, to produce proteins. The code is actually the sequence of bases in DNA. For example ATAGCGA. is a. We'll go over the steps of transcription and translation and the roles that ribosomes, DNA, and RNA play. Music Credit: Adrian Holovaty, OverClocked ReMix. Protein Synthesis 1. PROTEIN SYNTHESIS 2.
