Why are transcription and translation two separate but necessary steps for protein synthesis?

∙ 8y ago
The three types of RNA are all needed to perform protein synthesis.
- mRNA is needed to bring the code that is needed to be translated. Once transcribed within the nucleus, it moves out to the cytoplasm to be translated.
- tRNA is needed to bring the anticodon and amino acid to be combined to form proteins. It attaches to the codon on the mRNA.
- rRNA, combined with proteins forms the two parts of the ribosomes, which is where the tRNA and mRNA attach to begin translation.

∙ 12y agomRNA act as a template which contain information about protein in form of codons. mRNA is messenger RNA that transfers message about protein from DNA in nucleus to cytoplasm where it is converted to protein via process called Translation.

∙ 13y agoTranscription is the process in which the code on DNA is copied and creates a strand of messenger RNA (mRNA). This is necessary because the mRNA needs to take the genetic information to the ribosome so that the proteins can be made. The DNA can not leave the nucleus of a eukaryotic cell because it could get damaged. The mRNA goes from the nucleus to the ribosome, but it is okay if it gets degraded because it is only a copy.

∙ 8y agoProtein synthesis requires DNA codes that use RNA through transcription to make proteins in translation.
In transcription RNA will be made. Transcription is the process of RNA being created from DNA in 3 steps; initiation, elongation and termination. This process is to create RNA and uses the enzyme RNA polymerase.
Translation is the process of mRNA being used to make proteins in the ribosome. mRNA will attach to the ribosome which will assemble amino acids into a polypeptide chain.
Any mistake can cause a mutation which can be no problem or fatal.

Where do transcription and translation occur in prokaryotic cells?
It occurs in the cytoplasm of the cell. Transcription and translation occur in prokaryotes at the same time because of the lack of nuclear membrane.RNA polymerase transcribes through the terminator sequence, causing the polymerase to fall off the DNA and release the transcript.
What must happen to the DNA before transcription can take place?
It must unwind and separate for transcription to occur
What must happen to DNA strands before transcription can begin?
DNA strands must unwind and the two strands must separate prior to transcription beginning. Once transcription is complete, the two strands join back together.
Describe the transcription process in terms of the three regions of the gene?
Transcription takes place in three separate regions of the gene: the nucleus, DNA structure and the mRNA (or messenger ribonucleic acid).
How are the end result of transcription and replication different?
The difference between transcription and DNA replication is that transcription uses uracil.

What are two differences between transcription and translation?
Transcription is writing a word using letters from a different language.e.g. 'μήλο' becomes 'Milo'. As you can see the word has been rewritten with letters from the English alphabet, but is only readable by people who know Greek and English (because to read the word you must know the English to Greek letter transcriptions)Translation is writing the English version of a worde.g. 'μήλο' becomes 'Apple'. As you can see the word is now written in English, and is only readable by people who know English

What is DNA to RNA to protein called?
Okay, so here's how it works. DNA is read by an RNA polymerase, which "builds" the RNA to be complementary to a portion of the DNA strand. The RNA that is formed here is mRNA. tRNA is a separate thing of its own. Each tRNA molecule has a certain amino acid attached to it. As a ribosome "reads" the mRNA, tRNA molecules' anticodons bond temporarily to the codons of the mRNA, and the ribosome puts together the amino acids (from the tRNA molecules), forming a protein. So, indirectly, yes.

How you have 28?
It is necessary to separate 27 from 29
What is the difference between analysis and synthesis?
Analysis: The procedure by which we break down an intellectual or substantial whole into parts or components. Synthesis: To combine separate elements or components in order to form a coherent whole.
What is the scientific word for breaking down?
It is analysis, as opposed to synthesis - which is putting together.
How are the end result of transcription and replication different?
The difference between transcription and DNA replication is that transcription uses uracil.
How is dehydration synthesis and hydrolysis similar?
dehydration synthesis is when water is formed when combining two molecules. hydrolysis is adding water to make one molecule into two separate molecules.
When does chromatin replicate?
during S (DNA synthesis) phase of the cell cycle
