"mRNA" is an abbreviation for Messenger RNA. It carries the genetic code for protein to the rRNA (ribosomal RNA) and enzymes in the ribosomes where tRNA (transfer RNA) carries amino acids which are matched to the mRNA to form protein.
DNA is the originating molecule containing the master copy of the code. This is copied to the mRNA first.
The differences between DNA and RNA are that 1) RNA has uracil in place of thymine and 2) RNA uses ribose instead of the 2-deoxyribose in DNA. There are both double stranded and single stranded DNA and RNA in nature so this is not a defining difference.
It depends on what sort of organism it is as to where these compounds are in the cell but the process is similar. In the eukaryotes, there is an extra step that takes place in the nucleus where the mRNA is first cut and spliced.
What else can I help you with?
How is DNA replication affected by a lack of mRNA?
Not at all. mRNA is not involved in DNA replication as it is involved in transcription and translation.
DNA Transcription is the production of?
messenger RNA (mRNA)
A strand of mRNA has the bases guanine-adenine-uracil Which amino acid corresponds to these bases?
Asp
What is the difference between humans and archaea?
humans cells contain dna, but the cell of archaea do not
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
Difference between sense and anti sense strands of DNA?
The sense strand of DNA is the strand that has the same sequence as the mRNA that is transcribed from DNA. The antisense strand is the complementary strand of the sense strand, which is used as a template for mRNA synthesis. The mRNA is transcribed from the antisense strand and contains the same sequence as the sense strand.
How is mRNA differint from DNA?
The mRNA comes into the DNA when the DNA unzips. Then the mRNA attaches to one side of the DNA, copies it down, and leaves. Remember, AT CG
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
A DNA strand with the base sequence tgacgca codes for a strand of mrna the mrna will have what base sequence?
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
Where is the process of making mRNA from DNA called?
DNA to mRNA is transcription, whereas mRNA to tRNA is translation. The latter part is when proteins are made from ribosomes and instructions carried over by mRNA from the DNA.
What is made in transcription?
mRNA is made. Messenger (Ribose Nucleic-Acid). mRNA is a single strand of RNA made from the template strand of DNA. The mRNA is a exact copy of the coding or sense strand of DNA. The only difference between the produced RNA and DNA is the DNA has deoxyribose as its backbone sugar, and all Thymines have are replaced with Uracil.
What is the order of how a cell changes DNA messages to protein?
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein
What does transcriptase use to form DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
DNA sequence acgtt will give what mRNA base sequence?
The mRNA base sequence corresponding to the DNA sequence acgtt is ugcaa. The mRNA sequence is complementary to the DNA sequence, with thymine (T) in DNA being replaced by uracil (U) in mRNA.
What are the bases of mRNA coded for by this section of DNA before the mutation?
The bases of mRNA coded for by a DNA segment are complementary to the original DNA sequence. If the DNA sequences are ATCG, the corresponding mRNA bases will be UAGC.
What bridge between DNA and protein synthesis is needed?
Transcription is the bridge between DNA and protein synthesis. During transcription, a DNA sequence is copied into a messenger RNA (mRNA) molecule by the enzyme RNA polymerase. This mRNA molecule serves as a template for protein synthesis during translation.
What molecule carries the instructions for producing Mrna?
Instructions from DNA are carried to ribosomes by molecules of amino acids. These are carried by tRNA while mRNA carries information from the genes to ribosomes.
