What code tells a cell to stop making a protein?
A codon at the end of RNA signals the end of transcription. This is encoded by the codon sequence UAA, UGA, or UAG.
What are the steps involved in the process of transcription?
DNA unwinds/"unzips" as the Hydrogen Bonds Break.The free nucleotides of the RNA, pair with complementary DNA bases.RNA sugar-phosphate backbone forms. (by RNA Polymerase.)Hydrogen bonds of the untwisted RNA+DNA "ladder" break, freeing the new RNA
Describe the difference between a termination signal and a stop codon?
Termination signal is at the end of the part of the chromosome being transcribed during transcription of mRNA. While in a stop codon, also called termination codon, is a nucleotide triplet within messenger RNA that signals a termination of translation.
What signals a seed to awake?
The signals is the duration, intensity of light or the temperature
When your cells need energy they send signals to your brain how do these signals make you feel?
tired
What signals the termination of translation?
a terminator or transcription terminator disrupts the enzyme DNA polymerase. OLSEN BIO STUDENT
How does Transcription take place?
who? the transcription enzyme RNA polymerase, the promoter DNA and the terminator DNAwhere? in the cell nucleusInitiation The promoter, located in the DNA at the beginning of the gene becomes the binding site for the RNA polymerase. Elongation the RNA polymerase copies and peels away the copied DNA, after copied, the DNA joins back with its matching DNA strand while the newly made RNA leave the polymerase Termination the RNA polymerase reaches a special sequence of bases in the DNA template that signals the end of the gene.

What might geneticists learn about genes by studying RNA?
Molecular biologists have found that certain DNA sequences serve as promoters, bindings sites for RNA polymerases serve as starts and stops signals for transcription.
A DNA sequence that signals a gene's start is?
Promoters
What is a promoter in DNA?
A promoter is a sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it. A promoter is usually referred to as a "TATA (thymine, adenine, thymine, adenine) box" or a "CAAT (cytosine, adenine, adenine, thymine) box". As DNA polymerase makes its way down a section of DNA and comes across TATA box, or a CAAT box, that is the signal to begin transcription.
What is the terminator in mRNA synthesis?
a specific nucleotide sequence in DNA that signals a stop to transcription
