What are the 4 steps in the process of translation?
The four steps of translation are:
- Activation or charging of tRNA.
- Initiation – recognition of start codon, binding of ribosomal subunits to mRNA and formation of initiation complex with Met-tRNA at the P site.
- Elongation – peptide bond formation and growing of polypeptide chain.
What are the steps of interphase?
Interphase is defined by three stages: the first gap phase (G1), the synthesis (S) phase, and the second gap (G2) phase.
How do you translate a protein sequence?
Translation and Open Reading Frame Search Regions of DNA that encode proteins are first transcribed into messenger RNA and then translated into protein. By examining the DNA sequence alone we can determine the sequence of amino acids that will appear in the final protein.
What is interphase write its steps and features?
Interphase refers to the phase of the cell cycle in which a cell copies its DNA to prepare for mitosis. This phase is also referred to as the ‘daily living’ or the metabolic phase of the cell. Furthermore, in this stage, a cell gets nutrients and then metabolizes these nutrients.
What happens during the 3 stages of interphase?
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
What are the G0 G1, S and G2 phases of interphase?
There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. Some cells that do not divide or replicate stops at G1 or G0; G0 and G1 are sometimes the same thing.
How is DNA translated into mRNA?
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).
What are the steps of translation and protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
