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.
What happens when the cell is not in the presence of tryptophan?
RNA polymerase can transcribe mRNA
Where does mRNA travele to in a cell?
mRNA is usually targetted to ribosomes, which transcribe the sequence into a protein. Some mRNA molecules do not code for proteins but instead interract with DNA in the nucleus.
Which strand of DNA transcribes into mRNA?
The strand running in the 3'-5' end will be the one that RNA copies, as this is the direction of transcription
Where in the cell does mRNA transcribe genetic code?
Transcription is formation of RNA which takes place in nucleus .
A segment of DNA has the following sequence TTAAGGCC. Which sequence of bases would be found on the complementary strand of mRNA?
The complimentary strand of MRNA would be AAUUCCGG.

How do you transcribe DNA to complemetary RNA?
DNA dependent RNA polymerase is recruited by transcription factors on the promoter (TATA box) and starts transcribing mRNA from DNA by making a complimentary strand to the bottom strand in a 5' to 3' direction. Afterwards, the mRNA is capped with guanine-methyl, its introns are spliced out, and it's given a poly-A tail.
A segment of DNA has the following sequence ttaaggcc which sequence of bases would be found on the complementary strand of mrna?
TGCA
What sequence represents a dna strand that would compliment the following mrna strand cua ugc aug cca?
Gau acg uac ggc
How many strand of mRNA are transcribed from the two unzipped strands of DNA?
One mRNA strand is made.
How many strands does mRNA have?
a MRNA strand is a strand made up of messenger ribosenucleicacids
What would the DNA sequence have been for the following mrna strand cuc-aag-ugc-uuc?
mRNA forms a complementary sequence to the DNA it is transcribed from. Therefore, the DNA strand would be the complement (opposite base pair) from what is present in the mRNA. Also, remember that RNA uses uracil (U) in place of thymine (T). For the mRNA strand CUC-AAG-UGC-UUC, the complementary DNA strand would be GAG-TTC-ACG-AAG.
A protein contains 131 amino acids How many bases will there be on the mRNA strand corresponding to these amino acids and how do you know?
131*3=393 bases might be there on mRNA strand 3 codons of mRNA strand deduce an aminoacid of a protein, so here, mRNA strand bases are being asked.
What happens when the cell is not in the presence of tryptophan?
RNA polymerase can transcribe mRNA
What is formed when reverse transcriptase is used on strand of mrna?
A strand of DNA
What is formed when reverse transcriptase is used on of strand of mrna?
A strand of DNA
