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

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 two processes are necessary to build or separate macromolecules?
The two processes necessary to build or separate macromolecules are dehydration synthesis and hydrolysis. Dehydration synthesis involves removing water molecules to bond monomers together and form a larger macromolecule. Hydrolysis involves adding water molecules to break down a macromolecule into individual monomers.
How does RNA polymerase unwind the DNA double helix during transcription?
During transcription, RNA polymerase binds to a specific region of the DNA called the promoter. It then unwinds the DNA double helix by breaking the hydrogen bonds between the base pairs, allowing one of the DNA strands to serve as a template for the synthesis of RNA. This process is facilitated by the enzyme's helicase activity, which helps separate the two DNA strands and create a single-stranded template for RNA synthesis.
How are the end result of transcription and replication different?
The difference between transcription and DNA replication is that transcription uses uracil.
What must happen to DNA strands before transcription can begin?
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.

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

Does all transcription reports have a diagnosis heading?
No, not all transcription reports have a separate diagnosis heading. The structure of a transcription report can vary depending on the content and formatting preferences of the healthcare facility or provider. Some reports may include the diagnosis within the body of the report rather than as a separate heading.

What must happen to the DNA before transcription can take place?
Before transcription can take place, the DNA in the cell nucleus must be unwound and separated into two strands by enzymes. This process exposes the genetic information that will be transcribed into mRNA.
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
Why does chemiosmosis require a membrane?
Chemiosmosis involves the movement of ions across a membrane, which creates an electrochemical gradient that drives ATP synthesis. The membrane is necessary to separate the high and low concentration of ions, allowing for the generation of the proton gradient that powers ATP production.
Describe the transcription process in terms of the three regions of the gene?
Transcription is divided into three regions: the promoter, which signals the start of transcription; the coding region, where the gene sequence is transcribed into RNA; and the terminator, which signals the end of transcription. During transcription, RNA polymerase binds to the promoter region, unwinds the DNA, reads the coding region to synthesize RNA, and stops at the terminator region to release the newly formed RNA transcript.
