Which Answer Best Describes Rna Processing

Answer RNA processing is the term collectively used to describe the sequence of events through which the primary transcript from a gene acquires its mature form. RNA processing is the addition of a 5 cap and a poly-A tail to an mRNA.

It enables the RNA ribonucleic acid polymerase molecule to bind to the promoter site and initiate the transcription.

. During RNA processing an _____ is added to the 5 end of the RNA. A gene is a structural protein that defines a heritable trait. A The promoter is a site at which only RNA polymerase will bind.

A primary transcript is often much longer than the final RNA molecule that leaves the nucleus. The enzyme that synthesizes RNA is RNA polymerase RNA pol. Exons are cut out before mRNA leaves the nucleus.

Drag the correct labels under the diagrams to identify the events of RNA processing. Group of answer choices an enzyme that removes the sugar Group of answer choices an enzyme that removes the sugar A. At 5 end of mRNA a cap of 7-methylguanosine m 7 G or 7 Me G is added.

This process helps protect the mRNA from premature degradation. RNA Processing In prokaryotes no RNA processing is necessary. Ribozymes may function in RNA splicing.

The sigma factor is a molecule that is used for the initiation of transcription process in bacterial cells. The processing steps are. It carries the map of the gene sequence in the form of codons to the cytoplasm for translation of the protein.

Which of the following best describes a DNA molecule. ÐAddition of a 5 Õ 7-methyl guanosine cap capping. Which of the following is NOT true of RNA processing.

There are several enzymes in the replication process such as helicases ligases DNA polymerase RNA. Choose the nucleotide sequence of the RNA strand that would be complementary to the following strand. A gene is a segment of DNA that contains the information for transcription of an RNA.

Newly synthesized mRNA is called pre-mRNA. The newly formed RNA also known as the primary transcript is processed again after it has been transcribed. Which of the following statements best describes the promoter of a protein-coding gene.

RNA splicing can be catalyzed by spliceosomes. D The promoter is a nontranscribed region of a gene. Before the RNA leaves the nucleus the introns are removed and the exons are joined together producing an mRNA molecule with a continuous coding sequence.

In prokaryotic cells the core enzyme has five subunits 2α 1β 1β and 1Ω and possesses 5I 3I polymerase activity that elongates the growing RNA strand. The sigma factor itself does not bind to the RNA polymerase. Made of amino acids.

A gene is the unit of heritage mutation recombination and function. What is spliced together during mRNA processing. O An RNA molecules is transcribed from a DNA template.

This process is called RNA splicing. Processing of eukaryotic mRNA. Nucleotides may be added at both ends of the RNA.

Which statement best describes the job or function of the messenger RNA. It is the recognition site for the binding of a specific transcription factor. Ðthe nascent RNA is usually the mRNA.

Which of the following statements best describes the significance of the TATA box in the promoters of eukaryotes. In eukaryotes the nascent RNA is called primary transcript-RNA Ð needs to be processed Ðand transported to the cytoplasm for translation to occur. It is quite different from the mRNA that takes part in protein synthesis.

C The promoter is part of the RNA molecule itself. Introns are removed from pre-mRNA and the exons are joined together. B The promoter is a site found on RNA polymerase.

Which statement best describes a physical change 12 1 answer Does the following statement describe a function of DNA a function of RNA a function of both DNA and RNA or. O Exons are removed from pre-mRNA and the introns are joined together RNA is reverse-transcribed to make DNA. Post-transcriptional modification - splicing 5 prime cap and poly-A tail Complete the Concept Map to describe the process of protein synthesis.

Which best describes DNA polymerase. Question 36 Which statement best describes RNA processing in eukaryotic cells. At 3-end a tail consisting of 80-200 adenine nucleotides called Poly A tail is added.

Sigma factor binds to RNA polymerase to increase its processivity. D The promoter is a nontranscribed. Biology questions and answers.

A gene is an RNA which codes for translation of a protein.
