How does RNA polymerase know where to start transcribing a gene into mRNA?
The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.
What are the major steps of mRNA transcription?
mRNA is produced based on the DNA code. If the original (correct) sequence is AGC, then the correct mRNA sequence should be UCG.However, the mutated DNA sequence (ATC) now codes for the mRNA sequence UAG. So, the incorrect DNA sequence is spread through to create an incorrect mRNA sequence.
If the base sequence on one DNA strand is ATGGCCTAG what is the sequence on the strand of the helix?
The sequence on the strand of the helix is TACCGGATC.
What happens first during transcription?
RNA polymerase reaches the beginning of the gene
What determines protein structure?
The primary structure of proteins is the sequence of amino acids. The sequence is determined by DNA and genetics. RNA copies the code from DNA and it takes it over to the ribosomes. Then the amino acids are sequenced based on the "instructions."
If the sticky end of a nucleotide sequence is TTAA what is next?
If the sticky end of a sequence is TTAA, it can bind to a DNA molecule with the sequence AATT
How does Transcription take place?
who? the transcription enzyme RNA polymerase, the promoter DNA and the terminator DNAwhere? in the cell nucleusInitiation The promoter, located in the DNA at the beginning of the gene becomes the binding site for the RNA polymerase. Elongation the RNA polymerase copies and peels away the copied DNA, after copied, the DNA joins back with its matching DNA strand while the newly made RNA leave the polymerase Termination the RNA polymerase reaches a special sequence of bases in the DNA template that signals the end of the gene.

List the two nucleotide sequence that are complementary to the sticky end sequence on the human DNA?
It is GGCC and CCGG!

Which number should come at the end of the series 1 4 9 16?
The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.
What is the sequence of events that occurs from the end of one division to the end of the next division?
cell cycle
Finish sequence 1 5 17 53 161?
485 is not necessarily the end of the sequence, but it is the next number after those listed.

DNA molecule antiparallel Why?
The DNA molecule is anti-parallel. This is because the two strands are the opposite of one another, such that if one strand has the base sequence ATC, the opposite strand would have the base sequence TAG.
How would the following base sequence be coded for in mrna cag tgc acg?
Recall for any DNA sequence, there are actually two sequences because DNA is a double helix composed of two strands. By convention (a thankfully logical convention) we typically record the DNA sequence of the "sense strand" from the 5' end to the 3' end. The sense strand was chosen because the sense DNA sequence is exactly the same as the mRNA sequence except that it has T's where RNA has U's. Thus if the sequence you provided is the sense strand 5'-acagtgc-3', then the mRNA sequence would be 5'-acagugc-3'. However, if what you were asking for is what mRNA sequence would be transcribed from the given DNA sequence, that would depend if you'd given me the sequence 5' to 3' or 3' to 5'. If you've given me the sequence of the antisense strand, 3' to 5' (that is, if you're asking what would happen if an RNA polymerase landed at the left of the sequence and began moving right) the mRNA sequence would be ugucacg. If you've given me the sequence of the antisense strand 5' to 3', then the answer would be gcacugu. I'm sorry if I made this more complicated for you.... I have a feeling you were looking for a simpler answer than this.
How does RNA differantiate from DNA if it is double strnded?
the following points differentiates double stranded RNA And DNA : 1. the RNA is loop structure at the end and not that independent strands of the DNA. this loop is calles R-loop, t includes a sequence if repeated poly A tail. 2. it contains poly a tail at the end but DNA doesn't.
What is first located on a gene?
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
