, thymine, guanine, and cytosine. The genetic information is the sequence of nucleotides in the DNA. What is the process of transcription? - answerTranscription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA. This takes place in the nucleus. The genetic material serves as a template. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. What is the process o...

BIO1A03 - TEST 2 QUESTIONS AND ANSWERS RATED A what components are required for translation initiation/elongation/release factors mRNA aminoacyl tRNA synthases tRNA ribosome (ribosomal RNA + ribosomal subunit) what is the role of tRNA - transfer amino acids from the cytoplasm to a growing polypeptide strand in a ribosome - each tRNA molecule has a different shape and therefore translates a specific mRNA codon into a specific amino acid what is the structure of tRNA - made up of a single RNA st...

What is the Central Dogma of molecular biology? The central dogma of molecular biology explains that DNA encodes RNA through a process called transcription and RNA encodes protein through a process called translation. Describe how the information in DNA is used to produce specific proteins and can ultimately determine the characteristics of an individual organism. because of your DNA the certain RNA strand is coded from genes resulting in how your protein works. Describe the structure of DNA a...
