What are the three stages of translation Pogil?
What are the three stages of translation? Initiation, elongation, termination. Define each of the terms used in your answer to part A as they are used in everyday language.
What is synthesized during translation?
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.
Where in the cell does transcription take place Pogil?
nucleus
b. Where in the cell does transcription take place? In the nucleus.
What enzyme is required for transcription?
RNA polymerase
Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site.
Why is a molecule called transfer RNA?
Transfer RNA (tRNA) does this by carrying an amino acid to the protein synthetic machinery of a cell called the ribosome….Transfer RNA.

What are two things that occur during termination?
Describe two things that occur during termination? The stop codon signals for a protein known as a release factor to bind to the ribosome and adds a water molecule to the end of the amino acid chain. This reaction hydrolyzes the polypeptide chain from the tRNA, allowing the protein to exit the ribosome.
What are the 4 steps in transcription?
Transcription involves four steps:
- Initiation. The DNA molecule unwinds and separates to form a small open complex.
- Elongation. RNA polymerase moves along the template strand, synthesising an mRNA molecule.
- Termination. In prokaryotes there are two ways in which transcription is terminated.
- Processing.
How is the template strand read?
RNA polymerase synthesizes an RNA strand complementary to a template DNA strand. It synthesizes the RNA strand in the 5′ to 3′ direction, while reading the template DNA strand in the 3′ to 5′ direction. The template DNA strand and RNA strand are antiparallel.
