Which best describes a difference between transcription and dna replication
What is the difference between replication and transcription quizlet?
First, replication is the duplication of two strands of DNA, whereas transcription is the formation of a single identical DNA from the two stranded DNA.
What is the difference between DNA replication and translation?
By the replication of DNA, the complementary strands of DNA are synthesized by semi-conservative mode, while during the protein synthesis, the DNA transfers its message of language in the form of mRNA. By replication of DNA, two new strands are formed, by the process transcription-translation proteins are synthesized.
What is the main difference between transcription and translation?
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.
What is the best description of DNA replication?
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA? molecule.
What is the difference between DNA transcription for DNA synthesis and DNA transcription for protein synthesis?
Transcription for DNA synthesis occurs with both the “sense” and the “antisense” strands, while transcription for protein synthesis occurs with only the “sense” strand.
What is transcription in DNA replication?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). … This complex initiates transcription, and the RNA polymerase begins mRNA synthesis by matching complementary bases to the original DNA strand.
What two best describes DNA strands?
The two complementary DNA strands that compose a double-stranded piece of DNA are described as being antiparallel to each other. The term antiparallel means that while the two strands are physically parallel to one another, they run in opposite directions— much like the right and left lanes of a street.
What is translation and transcription?
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 point 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).
How does DNA replication quizlet?
dna replication – the dna molecule unwinds, and the two sides split. then new nucleotides are added to each side until twp identical sequences result. in prokaryotic cells, replication starts at a single site. in eukaryotic cells, replication starts at many sites along teh chorosome.
Where does DNA transcription occur?
nucleus
The process of Transcription takes place in the cytoplasm in prokaryotes and in nucleus in eukaryotes. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA.
Which statement best describes Strand characteristics as it relates to DNA replication?
What best describes strand characteristics as it relates to DNA replication? The leading strand is built continuously and the lagging strand is built in pieces. During DNA replication, which nucleotide will bind to an A nucleotide in the original or parental DNA strand?
What is transcription in DNA quizlet?
Transcription: Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
What happens during transcription and translation quizlet?
is the synthesis of polypeptide which occurs under the direction of mRNA. The cell translates the base sequence of an mRNA molecule into the amino acid sequence of an mRNA molecule into the amino acid sequence of polypeptide. is the synthesis of RNA under the directions of DNA (template).
What is transcription in biology quizlet?
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!
Does transcription make DNA?
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene’s DNA sequence. … Eukaryotic transcripts need to go through some processing steps before translation into proteins.
What is transcription of DNA quizlet nutrition?
-The transcription of DNA occurs when transfer RNA enters the cytoplasm. -The translation of DNA occurs in the nucleus of cells. -The transcription of DNA occurs in the nucleus of cells. The transcription of DNA occurs in the nucleus of cells.
What happens to DNA molecule after transcription?
After transcription, the DNA molecule reassociates to form its original structure. After transcription, the two strands of DNA pairs. And the formed RNA provides the site for protein synthesis i.e translation.
What is difference between RNA and DNA?
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
