What is the process of replication transcription and translation?
In humans, the nucleus of each cell contains 3 × 109 base pairs of DNA distributed over 23 pairs of chromosomes, and each cell has two copies of the genetic material. 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 happens in both transcription and translation?
Both processes occur in the cytoplasm in prokaryotes. The factor controlling these processes is RNA polymerase in transcription and ribosomes in translation. In transcription, this polymerase moves over the template strand of DNA, while in translation, the ribosome-tRNA complex moves over the mRNA strand.
What is the purpose of replication transcription and translation?
Making a Protein, Part 2: Translation
| Location | Purpose | |
|---|---|---|
| Replication | Nucleus | Duplicate a full strand of DNA |
| Transcription | Nucleus | Use a strand of DNA to build a molecule of mRNA |
| Translation | Cytoplasm | Use mRNA to build an amino acid chain |
Where do replication transcription and translation occur in the cell?
In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm.
What comes first transcription or translation?
Cell uses the genes to synthesize proteins. This is a two-step process. The first step is transcription in which the sequence of one gene is replicated in an RNA molecule. The second step is translation in which the RNA molecule serves as a code for the formation of an amino-acid chain (a polypeptide).
What are two differences between transcription and translation?
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 difference between replication and transcription?
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.
How are transcription, translation and replication related to each other?

What happens to RNA messenger RNA during transcription?
Three Types of RNA Messenger RNA (mRNA): copies the DNA of a gene in a process called transcription. Ribosomal RNA (rRNA): takes the mRNA code and translates it into a protein in a process called translation. Transfer RNA (tRNA): brings one specific amino acid to the rRNA.
How is the promoter involved in the transcription process?
The promoter basically “tells” the RNA polymerase where to start the transcription process. Transcription is initiated with the binding of RNA polymerase to the promoter site. The RNA polymerase then uncoils the DNA and separates the two strands. One of the strands is used as the template strand for transcription.
What happens to the instructions after DNA replication?
–The instructions are transferred from a gene (segment of DNA) to an RNA molecule. –This process is called transcription. –WAIT!!!! What is RNA??? RNA (Ribonucleic acid) Type of nucleic acid (made of nucleotides). Single stranded. Has a sugar called ribose (hence the name). Contains Nitrogen bases cytosine, guanine, adenine, and uracil.
