What is the correct product of transcription from this DNA?
DNA transcription produces a single-stranded RNA molecule that is complementary to one strand of DNA.
Answer and Explanation: The product of transcription is: D) RNA.
The product of transcription is RNA, which can be encountered in the form mRNA, tRNA or rRNA while the product of translation is a polypeptide amino acid chain, which forms a protein. Transcription occurs in the nucleus in eukaryotic organisms, while translation occurs in the cytoplasm and endoplasmic reticulum.
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
In transcription, a portion of the double-stranded DNA template gives rise to a single-stranded RNA molecule. In some cases, the RNA molecule itself is a "finished product" that serves some important function within the cell.
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.
Where does transcription occur? Transcription occurs in the nucleus. What is the end product of transcription? mRNA containing the sequence of a specific protein.
In transcription, only one strand of DNA is used as a template. First, the double helix of DNA unwinds and an enzyme, RNA Polymerase, builds the mRNA using the DNA as a template. The nucleotides follow basically the same base pairing rules as in DNA to form the correct sequence in the mRNA.
The end result is a polypeptide whose amino acid sequence mirrors the sequence of codons in the mRNA.
Answer and Explanation: The molecule produced by RNA polymerase during transcription is messenger RNA. During transcription DNA unzips to expose the genetic code. RNA polymerase reads the DNA to create a complementary message of DNA called messenger RNA (mRNA).
What happens to DNA after transcription?
The DNA template stays in the nucleus after transcription because the process of transcription, which involves the synthesis of RNA from a DNA template, occurs within the nucleus.
DNA replication is the semi-conservative synthesis of the cellular double-stranded DNA (parental molecule) to produce two double-stranded daughter molecules. Each one of the daughter molecules contains one parental strand, and one newly synthesized strand (Fig. 1, below).
Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
What is transcription? 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. Transcription takes place in the nucleus!
Transcription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA (mRNA).
Transcription takes place in three steps: initiation, elongation, and termination.
Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand.
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Replication creates identical DNA strands, while transcription converts DNA into messenger RNA (mRNA). Translation then decodes mRNA into amino acids, forming proteins essential for life functions.
- 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. Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop (termination) sequence in the gene.
What is the process of transcription?
DNA transcription is the process by which the genetic information contained within DNA is re-written into messenger RNA (mRNA) by RNA polymerase. This mRNA then exits the nucleus, where it acts as the basis for the translation of DNA.
Answer and Explanation:
At the end of this event, the mRNA is released into the cytoplasm and comes in contact with the ribosome machinery to facilitate protein production. The protein that was generated undergoes a chain of post-translational modifications which marks the completion of gene expression.
Transcription: DNA to mRNA
DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).
The final product of translation is proteins. During translation, the information encoded in messenger RNA (mRNA) is used to synthesize a specific protein. Ribosomes, along with transfer RNA (tRNA) molecules carrying amino acids, read the mRNA sequence in groups of three nucleotides called codons.
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
