In the central dogma of molecular biology, the genetic information is schematically shown to flow from DNA to DNA (by replication) and from DNA to mRNA (transcription) to protein (translation). In the latter, the genetic code from the mRNA is read as a trinucleotide codon, i.e. a set of three adjacent nucleotides.
DNA replication is the process of producing an exact copy of a polynucleotide strand such as DNA. The flow of genetic information will be from DNA to DNA by complementary base pairing in terms of adenine-thymine (AT) and guanine-cytosine (GC) base pairing. The enzymes involved in the process are DNA polymerases. Conversely, the flow of genetic info...
Protein biosynthesis is the biological process of creating protein molecules. The first step is amino acid synthesis. Amino acids may be produced from carbon sources, e.g. glucose. Nevertheless, not all amino acids need to be synthesized. Some of them can be obtained from dietary sources. After amino acid synthesis, transcription is the next step. ...
Three RNAs are involved in biological translations. They are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). 1. mRNA is the RNA produced from transcription. It is comprised of a 5′ cap, 5’UTR region, coding region, 3’UTR region, and poly(A) tail. The copy of a DNA segment for gene expression is located in its coding region. It ...
Codon, in biology, refers to the set of three adjacent nucleotides in mRNA. It is also called a triplet. It complementary base pair with the anticodon of aminoacyl-tRNA. Examples: 1. Guanine-Cytosine-Cytosine (GCC) is the codon for the amino acid alanine. 2. Guanine-Uracil-Uracil (GUU) codes for valine. 3. Cytosine-Uracil-Adenine (CUA) codes for le...
Anticodon refers to the sequence of three adjacent nucleotides located on tRNA. It complementary-base -pairswith the codon of mRNA. For example, the anticodon for glycine is CCC (Cytosine-Cytosine-Cytosine) that binds to the codon GGG (Guanine-Guanine-Guanine) of mRNA.
Prior to initiation, a pre-translation step occurs. Called bio-activation, the amino acid binds to the corresponding tRNA by a covalent bond.
The major steps of translation in prokaryotes and eukaryotes are the same (i.e. initiation, elongation, translocation, and termination) and in both cells occurs on the ribosome. Translation in prokaryotes, though, occurs on 70S-type of ribosomes whereas translation in eukaryotes occurs on 80S-type of ribosomes. Because prokaryotes lack membrane-bou...

Retrieved from Iupui.edu website: https://www.biology.iupui.edu/biocourses/N100/2k3ch13dogma.htmlApr 7, 2019 · Translation refers to the process of creating proteins from an mRNA template. The sequence of nucleotides on the RNA is translated into the amino acid sequence of proteins and this reaction is carried out by ribosomes.
In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.
Jul 30, 2022 · Translation begins when an initiator tRNA anticodon recognizes a codon on mRNA. The large ribosomal subunit joins the small subunit, and a second tRNA is recruited. As the mRNA moves relative to the ribosome, the polypeptide chain is formed.
Aug 31, 2020 · 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.
