what is one significant difference between transcription and dna replication?
136
Transcription copies the DNA into RNA, while replication makes another copy of DNA. Both processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in gene expression and the other involved in cell division.

Though the function of both polymerases is to synthesise nucleic acid, both are functionally different. The DNA polymerase has polymerization as well as proofreading activity while the RNA polymerase only has the polymerization activity. ... The end process of synthesis is also different in both.

Originally Answered: Can you tell the difference between the original and the replicated strand? The DNA replication it is a semiconservative process, as the name suggests the replicated DNA will be made of a newly synthetized strand while the original one it is made of both the old strands .

Formation of pre-messenger RNA The mechanism of transcription has parallels in that of DNA replication. ... Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand.

The non-template DNA strand, which runs in the 5' to 3' direction is referred to as the coding strand since it contains the same nucleotide sequence in the mRNA strand. Therefore, the main difference between template and coding strand is their ability to be transcribed by RNA polymerases. Reference: 1.

DNA replication is the process of producing two identical copies of DNA, in which each template for the synthesis of a new complementary daughter strand. The central enzyme involved is DNA polymerase, which catalyzes the joining of deoyribonucleoside 5'-triphosphates (dNTPs) to form the growing DNA chain.

Transcription uses one of the two exposed DNA strands as a template; this strand is called the template strand. The RNA product is complementary to the template strand and is almost identical to the other DNA strand, called the nontemplate (or coding) strand.

In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.

The cellular processes of DNA replication and transcription involve DNA and RNA synthesis, respectively. DNA synthesis uses dNTPs as substrates, while RNA synthesis uses NTPs as substrates. ... Nucleic acid synthesis is catalyzed by either DNA polymerase or RNA polymerase for DNA and RNA synthesis respectively.

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.

In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled. Hence, this is the main difference between replication and duplication of DNA.

DNA Polymerase synthesizes a DNA strand and used in DNA replication while RNA Polymerase is used during transcription to synthesize the MRNA strand. In contrast with the DNA polymerase, RNA polymerases do not necessarily require the so called primer to start the process and they actually have no proofreading systems.

DNA replication is kind of like mitosis, where DNA is copied and has a "clone" of itself. It is useful for biological inheritance and is the basis of all of it. Protein synthesis makes proteins, while DNA replication makes DNA . DNA replication occurs in the nucleus and produces two identical sets of DNA.

Replication occurs in the S phase of cell cycle while Transcription occurs in G1 and G2 phases of cell cycle. Enzymes involved in replication are DNA helicase, DNA polymerase, gyrase (in eukaryotes) and in transcription RNA polymerase, Transcriptase plays a major role.

Transcription occurs in the nucleus of the cell. Translation occurs in the cytoplasm of the cell. Replication occurs in the nucleus of eukaryotic cells.

Summary of Differences Between DNA and RNA DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable.
