what are the differences between dna replication and transcription?
15311
Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production of new nucleic acids- DNA or RNA.

1. DNA polymerase synthesizes DNA while RNA polymerase synthesizes RNA. 2.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.

What is the difference between transcription and translation? Transcription is the synthesis of RNA from DNA. Occurs in the nucleus. Translation is the synthesis of a protein from RNA.

1. DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Transcription is the process of synthesis of RNA using DNA as a template. ... To make RNA copies of individual genes.

The synthesis of RNA molecules using DNA strands as the templates so that the genetic information can be transferred from DNA to RNA. Similarity between replication and transcription: 1- Both processes use DNA as the template. 2- Phosphodiester bonds are formed in both cases.

What is the difference in what they do? DNA stores and transmits genetic information. RNA acts as a template for making proteins. DNA is found in the nucleus only.

Gene expression is the bio-process by which DNA is "transformed" into protein, whereas DNA replication is the bio-process by which the double-helix DNA system is duplicated. ... Gene expression also is source of great errors, such as in splicing, a process by which the mRNA is "edited."

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. ... Transcription only occurs when a gene is turned on.

"DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. ... The two basic differences between RNA and DNA are: RNA is usually single stranded, while DNA is usually double stranded. RNA doesn't contain cytosine, while DNA doesn't contain adenine."

DNA plymerase:replicate whole DNA chromosome - synthesize daughter strands from the parental strands. RNA polymerase:transcribe messenger RNA from DNA strand. DNA plymerase and RNA polymerase -both adds one nucleotide at a time to the 3' end of strand and proceed the synthesis of strand from5' to 3' direction .

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.

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

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.

What are the differences between DNA and RNA? While the sugar for DNA is deoxyribose, the sugar for RNA is simply ribose. DNA is double stranded, while RNA has a single strand. ... Transcription is the process by which DNA is copied into mRNA.

DNA transcription produces a single-stranded RNA molecule that is complementary to one strand of DNA. Transcription, however, differs from DNA replication in several crucial ways. Unlike a newly formed DNA strand, the RNA strand does not remain hydrogen-bonded to the DNA template strand.

Go with Brian's excellent answer! Plus, DNA replication occurs within the nucleus. While transcription, the beginning phase of protein synthesis also takes place within the nucleus. Then, the process of translation completes the synthesis of proteins, outside the nucleus, within the cell's cytoplasm.

RNA is created by transcription, or making a copy of DNA. RNA polymerase is the protein that makes the copy of DNA. Ribosomal RNA (rRNA) is part of the ribosome, or protein builders, of the cell. Ribosomes are responsible for translation, or the process our cells use to make proteins.
