Which of these occurs during transcription?

Which of these occurs during transcription?

Terms in this set (5) During transcription, RNA nucleotides line up with their complementary DNA partners, transcribing the information in DNA into RNA. Which of the following is a correct statement about mRNA? mRNA moves from the nucleus to the cytoplasm following RNA processing.

What happens in transcription quizlet?

What happens during transcription? During transcription, RNA polymerase binds to DNA and separates the DNA strands. RNA polymerase then uses one strand of DNA as a template from which nucleotides are assembled into a strand of RNA. During translation, the cell uses information from messenger RNA to produce proteins.

Which occurs during transcription Brainly?

Answer Expert Verified During transcription, mRNA is synthesized using DNA as a template. This process usually takes place in the cell nucleus and is carried out with the help of an enzyme called RNA polymerase. mRNA plays the role of a messenger hence the term messenger RNA or mRNA in short.

Which describes something that occurs during translation?

Which describes something that occurs during translation? In translation, messenger RNA (mRNA) is decoded in the ribosome decoding center to produce a specific amino acid chain, or polypeptide, describes something that occurs during translation.

Which best describes a promoter?

Solution: The promoter is a nontranscribed region of a gene. The promoter is the regulatory region of a protein-coding gene at which RNA polymerase must bind to initiate transcription—it is not transcribed into the RNA.

What is created between 2 amino acids during translation?

Peptide bond is a strong chemical bond that is formed between the amino group and carboxyl group of the molecules. Two amino acids are linked through the peptide bond during the process of translation. The formation of peptide bond during translation requires energy in the form of ATP. Thus, the answer is peptide bond.

What are the 4 steps of translation?

Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide). Amino acids are brought to ribosomes and assembled into proteins.

What are the 5 steps of translation?

The multi-step translation process professional translators use

  • Step 1: Scope out the text to be translated.
  • Step 2: Initial translation.
  • Step 3: Review the accuracy of the translation.
  • Step 4: Take a break.
  • Step 5: Refine translation wording.

How is a protein made step by step?

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.

What is the correct order for protein synthesis?

The correct sequence of events in protein synthesis is transcription, then translation.

What are the 9 steps of protein synthesis?

Terms in this set (9)

  • DNA unravels, exposing code.
  • mRNA comes in.
  • transcription (copying genetic code from DNA)
  • mRNA exits nucleus, goes to ribosome.
  • translation (gives message to ribosome)
  • tRNA brings in specific amino acids (anticodons)
  • protein synthesis begins.
  • peptides.

What are the two phases of protein synthesis?

Protein synthesis can be divided broadly into two phases – transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a template molecule called messenger RNA (mRNA).

What triggers protein synthesis?

Protein ingestion and resistance exercise both stimulate the process of new muscle protein synthesis (MPS) and are synergistic when protein consumption follows exercise. In healthy persons, changes in MPS are much greater in their influence over net muscle gain than changes in muscle protein breakdown (MPB).

What is the goal of transcription?

The goal of transcription is to make a RNA copy of a gene’s DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.

What are the steps of 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.

What are the 3 basic steps of transcription?

Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure 2.

What is transcription example?

Each gene on a chromosome can be thought of as the instructions for making a particular protein in a cell. Examples of these other kinds of RNA are transfer RNA (tRNA) and ribosomal RNA (rRNA), which are both critical to the process of protein synthesis. …

What is the end result of transcription?

Explanation: Transcription results in production of RNA , it can be mRNA , rRNA and tRNA.

What is the main result of transcription?

The individual nucleotides that are read off of the DNA template strand are transcribed into the nucleotides of the corresponding RNA, so the final result is a single-stranded polymer, namely the mRNA, whose nucleotides correspond exactly to the complementary nucleotides on the DNA strand with the exception that …

Is DNA directly involved with transcription?

Is DNA directly involved in Transcription? Is DNA directly involved in Translation? no, DNA remains in the nucleus and this process doesn’t occur in the nucleus. Which types of RNA are involved in Translation?

What is the result of RNA transcription?

As opposed to DNA replication, transcription results in an RNA complement that includes the nucleotide uracil (U) in all instances where thymine (T) would have occurred in a DNA complement. Only one of the two DNA strands serve as a template for transcription.

Is RNA synthesized 5 to 3?

The RNA is always synthesized in the 5′ → 3′ direction (Figures 10-10 and 10-11), with nucleoside triphosphates (NTPs) acting as substrates for the enzyme.

What is the process of RNA transcription?

Transcription is the process in which a gene’s DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the main transcription enzyme. RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule.

What happens to RNA after translation?

Messenger RNA (mRNA) mediates the transfer of genetic information from the cell nucleus to ribosomes in the cytoplasm, where it serves as a template for protein synthesis. Once mRNAs enter the cytoplasm, they are translated, stored for later translation, or degraded. All mRNAs are ultimately degraded at a defined rate.

What happens if mRNA fails to be translated?

Answer and Explanation: An mRNA strand will go to the ribosome where it is translated into a protein. If mRNA fails to be translated then the ribosomes will be unable to create proteins.

What happens to mRNA after processing is complete?

The process of removing the introns and rejoining the coding sections or exons, of the mRNA , is called splicing. Once the mRNA has been capped, spliced and had a polyA tail added, it is sent from the nucleus into the cytoplasm for translation.

What destroys mRNA?

Histone mRNA degradation begins when a string of uridine molecules are added to the tail end of the molecule — a process known as oligouridylation. This signals a complex of proteins known as the exosome to begin degrading the mRNA. These processes are repeated until the mRNA is completely broken down.
