Translocation is the process by which the ribosome slides down the mRNA so a new cycle of elongation can begin.
What is the function of RNA polymerase quizlet mastering biology?
What is the function of RNA polymerase? It adds nucleotides to the 5′ end of the growing mRNA molecule. It proceeds slowly along the DNA strand, requiring about a minute to add two nucleotides to the growing mRNA molecule. It unwinds the double helix and adds nucleotides to a growing strand of RNA.
What is mastering biology?

What is Pearson’s MyLab and mastering?
Pearson MyLab & Mastering is an interactive educational system designed to accompany textbooks published by Pearson Education. When this tool is added to a Canvas course, instructors and their students can use Pearson’s interactive instructional materials, including homework, quizzes, and multimedia tutorials.
Which of the following is the site of transcription?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA (mRNA) molecule.
What is the process called that converts the genetic information?
It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
What is the function of RNA polymerase mastering biology?
What is the function of RNA polymerase? It unwinds the double helix and adds nucleotides to a growing strand of RNA.
What is the role of RNA polymerase It creates the DNA strand?
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.
How does RNA polymerase know where to start transcribing a gene into mRNA quizlet?
How does RNA polymerase know where to start transcribing a gene into mRNA? RNA polymerase starts when the enzyme attaches to a certain nucleotide sequence called a promoter at the beginning of a gene. Transfer RNA acts to translate the message to RNA polymerase.
What is the function of structure e?
What is the function of Structure E? stabilization of the phospholipids. – (Cholesterol helps to stabilize the structure of the plasma membrane.)
How do you master in biology?
- Make learning a daily routine.
- Flesh out notes in 24-48 hour cycle. ”
- Study to understand, not just to memorize words.
- Learn individual concepts before integrating it together.
- Use active study methods.
- You need to test yourself frequently to truly gauge how much you comprehend.
What is the difference between an F+ donor and an HFR donor?
What is the difference between an F+ donor and an Hfr donor? The Hfr donor has an F factor integrated into its main chromosome, but the F+ donor does not.
What is mastering by Pearson?
Mastering® is the teaching and learning platform that empowers you to reach every student. When combined with educational content written by respected scholars across the curriculum, Mastering helps deliver the learning outcomes that students and instructors aspire to.
What can teachers see on Pearson?
Teachers can also view progress and usage data for all assignments. The Data tab of Pearson Realize provides class and student data, including mastery, overall progress and time on task. Teachers can also view data for individual students in the class mastery by standards report, progress report, and usage report.
Is there an app for Pearson MyLab?
The Pearson eText Pearson eText app for your device works on most iOS and Android smartphones and tablets. The Pearson eText app lets you read and study your book flexibly on your mobile device, whether on a smartphone or a tablet.
What are the 3 stages of transcription?
It involves copying a gene’s DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.
What are the 4 steps of transcription?
The major steps of transcription are initiation, promoter clearance, elongation, and termination.
Where is the site of translation?
Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.
What are the 3 processes of 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).
What is the process that converts the genetic information stored in DNA to RNA copy?
Transcription is the process by which a DNA template is used for the manufacture of several different types of RNA.
What is the process of conversion of DNA into RNA?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.
What determines which base is added to an RNA strand during transcription mastering biology?
In RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where the first base is the coding base in the template strand of the DNA and the second base is the base that is added to the growing mRNA strand.
Which of the following events occurs during the process of transcription mastering biology?
Which of the following events occurs during transcription? A molecule of RNA is formed based on the sequence of nucleotides in DNA. During transcription, RNA nucleotides line up with their complementary DNA partners, transcribing the information in DNA into RNA.
What is the difference between DNA polymerase and RNA polymerase?
DNA polymerase catalyses the replication of DNA and produces new DNA strands, whereas, RNA polymerase catalyses transcription, i.e. synthesis of RNA from DNA.
What is the function of DNA polymerase and RNA polymerase?
DNA and RNA polymerase are the two enzymes responsible for the synthesis of DNA and RNA molecules from the genetic material inside the nucleus. DNA polymerase is used in DNA replication while RNA polymerase is involved in transcription.
