Replication, Transcription, and Translation are the three main processes used by all cells to maintain their genetic information and to convert the genetic information encoded in DNA into gene products, which are either RNAs or proteins, depending on the gene.
What are the 3 parts of the central dogma?
What is the Central Dogma?From existing DNA to make new DNA (DNA replication?)From DNA to make new RNA (transcription)From RNA to make new proteins (translation).21 Jul 2021
What two processes make up the central dogma?
These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein.
What is the first step of translation?
Translation is generally divided into three stages: initiation, elongation, and termination (Figure 7.8). In both prokaryotes and eukaryotes the first step of the initiation stage is the binding of a specific initiator methionyl tRNA and the mRNA to the small ribosomal subunit.
Is gene expression the same as the central dogma?
Thus, during expression of a protein-coding gene, information flows from DNA → RNA → protein. This directional flow of information is known as the central dogma of molecular biology. For either type of gene, the process of going from DNA to a functional product is known as gene expression.
What are the main stages of translation?
Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
What occurs during translation?
What happens during translation? During translation, a ribosome uses the sequence of codons in mRNA to assemble amino acids into a polypeptide chain. The correct amino acids are brought to the ribosome by tRNA. The decoding of an mRNA message into a protein is a process known carries out both these tasks.
What is the central dogma of viruses?
As obligate intracellular parasites, viruses are completely dependent upon a host cell for their replication. The Central Dogma of Molecular Biology states that DNA is replicated to create more DNA, DNA is transcribed into mRNA, and mRNA is translated by ribosomes to create proteins.
