Would there be a problem if the RNA polymerase transcribed the wrong strand of DNA and the cell tried to make a protein?
Interesting question. I don't think there would be an issue, for the following reason:
Scientists actually deliberately put short sections of RNA made from the wrong strand of DNA in to cells sometimes. It's done because the short section of RNA from the wrong strand of DNA binds to the naturally made mRNA transcript. Ribosomes aren't able to translate double stranded RNA so if you put enough RNA from the wrong strand in you actually stop (or nearly stop) expression of the protein from that gene. From a lab experimental perspective, that's really useful. It's called small interfering RNA and the process overall is known as RNA interference (you can read about both on Wikipedia). I don't think RNA interference as a technique has a problem with cell death (which is generally what happens when cells are unhappy).
I suspect it would also be quite difficult for a cell to make a protein from the wrong strand of DNA, simply because transcription starts with the codon for methionine, which would be missing at the beginning of the transcript (you'd get the code for tyrosine instead). In fact, you'd have to wait till what would normally be a tyrosine codon in your 'right' DNA strand before you got a methionine and hence a 'start' codon.
What else can I help you with?
How is dna made into mRNA?
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.
Which protein would you need to complete the synthesis of a new strand of DNA?
You would need a DNA polymerase protein to complete the synthesis of a new strand of DNA. DNA polymerase is an enzyme that assembles new DNA strands by adding nucleotides one by one in the 5' to 3' direction.
What kind of macromolecule is DNA polymerase?
DNA polymerase is an enzyme that helps catalyze the polymerization of DNA bases (deoxyribonucleotides) into a DNA strand.
What protein does DNA polymerase remove as it adds nucleotides?
When the replication fork is moving towards DNA double strand in the direction 5'- 3', a "Single-strand Binding Protein" (or SSB) -a dnaB gene product- must be removed in order to allow DNA polymerase to add the following nucleotide.
What enzyme is responsible for decodingthe DNA strand into an mRNA?
The enzyme responsible for decoding the DNA strand into an mRNA is called RNA polymerase. It catalyzes the synthesis of mRNA during transcription by matching complementary RNA nucleotides with the DNA template strand.
How is RNA transcribed within a cell?
RNA is transcribed within a cell by a process called transcription. During transcription, an enzyme called RNA polymerase reads the DNA sequence and creates a complementary RNA strand. This RNA strand then serves as a template for protein synthesis.
How is DNA transcribed into mRNA?
DNA is transcribed into mRNA through a process called transcription. During transcription, an enzyme called RNA polymerase reads the DNA sequence and creates a complementary mRNA strand by matching nucleotides. This mRNA strand carries the genetic information from the DNA and serves as a template for protein synthesis.
The strand of DNA that is not transcribed is called the strand.?
The strand of DNA that is not transcribed is called the coding strand. This strand serves as the template for mRNA synthesis during transcription. The opposite strand, which is transcribed into mRNA, is known as the template strand.
How is dna made into mRNA?
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.
How many strands of RNA are transcribed from the two unzipped strands of DNA?
One strand of RNA is transcribed from each of the two unzipped strands of DNA during transcription. RNA polymerase synthesizes a complementary RNA strand to one of the DNA strands.
Which protein would you need to complete the synthesis of a new strand of DNA?
You would need a DNA polymerase protein to complete the synthesis of a new strand of DNA. DNA polymerase is an enzyme that assembles new DNA strands by adding nucleotides one by one in the 5' to 3' direction.
RNA polymerase is an example of a?
enzyme involved in transcription, which is the process by which DNA is transcribed into RNA. RNA polymerase is responsible for binding to a gene's DNA and synthesizing an RNA molecule complementary to the DNA template strand.
How is transcription catalyzed by the enzyme?
Transcription is catalyzed by the enzyme RNA polymerase, which binds to the DNA template and synthesizes a complementary RNA strand by adding nucleotides in a specific order. This process allows the genetic information stored in the DNA to be transcribed into RNA molecules for protein synthesis.
Name of the DNA strand which is copied to make mRNA?
The DNA strand that is copied to make mRNA is the template strand of the gene. This strand serves as a template for the RNA polymerase enzyme to synthesize a complementary mRNA strand during the process of transcription.
How does mRNA get the code for gene from DNA?
mRNA is basically instructions for the creation of a protein. (the m stands for messenger) proteins are made in the ribosomes and they are made from 'amino acids' and basically these mRNA's tell the amino acids how to align to make a specific protein.
What kind of macromolecule is DNA polymerase?
DNA polymerase is an enzyme that helps catalyze the polymerization of DNA bases (deoxyribonucleotides) into a DNA strand.
What protein does DNA polymerase remove as it adds nucleotides?
When the replication fork is moving towards DNA double strand in the direction 5'- 3', a "Single-strand Binding Protein" (or SSB) -a dnaB gene product- must be removed in order to allow DNA polymerase to add the following nucleotide.
