What are the differences between DNA and mRNA and how do they function differently within the cell?
DNA is the genetic material that carries the instructions for making proteins in the cell, while mRNA is a temporary copy of a specific gene that carries the instructions from the DNA to the ribosomes for protein synthesis. DNA is double-stranded and located in the cell's nucleus, while mRNA is single-stranded and found in the cytoplasm. DNA remains in the nucleus, while mRNA travels to the ribosomes to direct protein synthesis.
Which mrna base always pairs with what DNA base?
In the base pairing between mRNA and DNA, the mRNA base adenine (A) pairs with the DNA base thymine (T). Conversely, uracil (U) in mRNA pairs with adenine (A) in DNA, as uracil replaces thymine in RNA. Cytosine (C) pairs with guanine (G) in both DNA and mRNA, and guanine (G) pairs with cytosine (C).
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
Does the mrna model more closely resemble the DNA strand from which it was transcribed?
Yes, the mRNA model closely resembles the DNA strand from which it is transcribed, but with some key differences. mRNA is synthesized using one strand of DNA as a template and contains uracil (U) instead of thymine (T). Additionally, mRNA is typically single-stranded, whereas DNA is double-stranded. Overall, mRNA carries the genetic information necessary for protein synthesis, mirroring the coding sequence of the DNA template.
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
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 the order of how a cell changes DNA messages to protein?
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein
Did the mRNA model more closely resemble the DNA strand from which it was transcribed?
Yes, the mRNA model closely resembles the DNA strand from which it was transcribed, specifically in terms of the sequence of nucleotides. However, there are key differences: mRNA contains uracil (U) instead of thymine (T), and it is typically single-stranded rather than double-stranded like DNA. Additionally, mRNA is a complementary copy of the coding strand of DNA, reflecting the genetic information needed for protein synthesis.
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.
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.
