What does reverse transcriptase use from DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
What is the complementary DNA sequence to AATCCGAT is?
In the cases of MRNA and DNA there are differences in the base pairs that make up the two compounds. In a situation in which Adenosine, Thymine, and Cytosine would need to be paired between DNA and RNA Guanine would be used on the RNA side.
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
What is the mRNA of DNA tac?
AUGremember the base pairing rules...the only differences in mrna is that Adenine binds with uracil because thymine does not exist in mRNAA=UT=AC=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 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
What is the difference between mRNA and DNA?
"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.
How is mRNA different from DNA?
Double stranded DNA contains all of the information that each and every Cell requires; the process called 'transcription' copies this information in the form of messenger Rna that is then transported, through the nuclear membrane, to the Ribosomes - located in the endoplasmic reticulum (ER) - where 'translation' - the production of proteins - takes place..
What is the order of actions by rna polymerase?
Binds to DNA, makes mRNA from DNA, detaches
What is used to carry the genetic code from DNA to the ribosomes?
The mRNA carries the genetic code needed to make a protein to the ribosome from DNA via microtubules.
Carries the message of DNA to ribosomes?
mRNA (messenger RNA) carries the instructions for protein synthesis from the DNA to the ribosomes.
