Which is the correct order of events when a protein is made in the process of translation?
During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein.
Which is the main event of translation termination?
Translation ends in a process called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. Stop codons are recognized by proteins called release factors, which fit neatly into the P site (though they aren't tRNAs).
What is the central dogma hypothesis of genetics quizlet?
The central dogma of molecular biology describes the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA → RNA → protein. Transcription is the synthesis of an RNA copy of a segment of DNA.
Is the process of decoding DNA into messenger RNA?
In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
Which is the correct order of events when a protein is made in the process of translation quizlet?
The correct sequence of events in translation is: A. initiation, termination, elongation.
What is the correct order of events during transcription?
Transcription takes place in three steps: initiation, elongation, and termination.
Which process occurs immediately before translation?
What must happen before translation can occur? messenger RNA must be transcribed from DNA in the nucleus.
How is DNA replication transcription and translation related?
The Central Dogma of Molecular Biology states that DNA makes RNA makes proteins (Figure 1). The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
What is the central dogma of DNA replication?
The central dogma states that the pattern of information that occurs most frequently in our cells is: From existing DNA to make new DNA (DNA replication?) From DNA to make new RNA (transcription) From RNA to make new proteins (translation).
What happens first in DNA replication?
The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).
Where does DNA replication occur?
interphase nuclei DNA replication occurs in the interphase nuclei of eukaryotic cells. DNA replication occurs before mitosis at the S-stage (synthesis) of the cell cycle.
What is the process of decoding DNA called?
In biology, translation refers to the process in which a genetic code from the mRNA is decoded by the ribosome in order to produce proteins.
What is the correct sequence of events in transcription and translation?
Answer and Explanation: The correct answer is (A) Initiation, Elongation, Termination. Transcription produces a molecule of mRNA from a gene sequence in DNA.
What are the 4 steps of DNA transcription?
The major steps of transcription are initiation, promoter clearance, elongation, and termination.
What are the steps of DNA transcription?
Transcription occurs in the three steps—initiation, elongation, and termination—all shown here….The steps are illustrated in Figure 2.
- Step 1: Initiation. Initiation is the beginning of transcription. …
- Step 2: Elongation. Elongation is the addition of nucleotides to the mRNA strand. …
- Step 3: Termination.

Which process occurs immediately before translation quizlet?
What must happen before translation can occur? messenger RNA must be transcribed from DNA in the nucleus.
Does replication or transcription happen prior to cell division?
Differences. DNA replication occurs in preparation for cell division, while transcription happens in preparation for protein translation. DNA replication is important for properly regulating the growth and division of cells.

During what phase of the cell cycle is DNA replicated?
S phase S phase is the period during which DNA replication occurs.
What happens during the start of DNA replication?
DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand.
How does semi-conservative replication work?
According to the semiconservative replication model, which is illustrated in Figure 1, the two original DNA strands (i.e., the two complementary halves of the double helix) separate during replication; each strand then serves as a template for a new DNA strand, which means that each newly synthesized double helix is a …
Why is DNA replication semi-conservative?
DNA replication is a semi-conservative process, because when a new double-stranded DNA molecule is formed: One strand will be from the original template molecule. One strand will be newly synthesised.
What does semi-conservative mean in DNA?
Definition of semiconservative : relating to or being genetic replication in which a double-stranded molecule of nucleic acid separates into two single strands each of which serves as a template for the formation of a complementary strand that together with the template forms a complete molecule.
Where does semi-conservative replication occur?
Semiconservative replication describe the mechanism of DNA replication in all known cells. DNA replication occurs on multiple origins of replication along the DNA template strand (antinsense strand).
What is translation and transcription?
Transcription is the synthesis of RNA from a DNA template where the code in the DNA is converted into a complementary RNA code. Translation is the synthesis of a protein from an mRNA template where the code in the mRNA is converted into an amino acid sequence in a protein.
Which of the following is the first step in DNA replication?
The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).
What are the steps of replication of DNA in a cell?
There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
What is DNA replication and how does it work?
Definition. DNA replication is the process by which the genome's DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.
During which phase of the cell cycle does DNA duplication or replication take place?
S phase S phase is the period during which DNA replication occurs.
Is replication of DNA Semiconservative?
DNA replication is a semi-conservative process, because when a new double-stranded DNA molecule is formed: One strand will be from the original template molecule.
