a. If you knew the amino acid sequence of a peptide could you use that information to find the gene in a pool of genomic DNA. If so, how might you do this.
b. How does a cell recognize which strand is the sense strand? How does the RNA polymerase enzyme actually know where to start making a message. How about stopping?
(Detailed explanation please)

a)
--> The amino corrosive coded can tell the three base which together structure codon on mRNA to code for that specific amino corrosive. The mRNA succession would thus be able to help in realizing DNA arrangement by complementary to layout strand.
b)
-->The 3' end of layout strand have advertiser district which helps in acknowledgment of this site by RNA polymerase compound, the terminal region is available 5' downstream of format strand. The barrette GC and U is shaped in prokaryotes while in eukaryotes oligo arrangement polyadenylation and DNA restricting element are utilized for endonuclease action.

A peptide from a novel bacterial protein was isolated and sequenced. The amino acid sequence is NH2-Leu-Met-Pro-Tyr-Ser-Ala-Ala-Pro-Cys-Leu-Trp-Glu-Ala-Gly-Asp-Arg-COOH. To verify and clone the gene encoding this protein from this uncharacterized bacterium, a student has to purify the bacterial genomic DNA and use it as the template to isolate the DNA fragment that encodes this peptide using PCR. The student plans to design a pair of oligonucleotides as the forward and reverse primers to PCR the DNA fragment that encodes this peptide....
1. Do all parts: a. The sequence of a gene on mRNA is normally AUGCCCGACUUU. The point mutation in the gene results in the MRNA sequence AUGCCGGACUUU. What are the amino acid sequence for the normal and mutant proteins? Say, with an explanation whether you expect this to be a silent mutation. b. Why is DNA polymerase said to be template-directed? If a RNA had the nucleotide sequence 5'-AUGCCAUAACGAUACCCCAGUC-3', what was the sequence of the DNA strand that was transcribed...
15. Determine the amino acids following mRNA molecules. ne the amino acid sequence a ribosome would translate from the *GCACCAUGCAAAGCGGGGAUUAGACCUUU-3 Caution: from which end of the RNA strand does the ribosome begin translating? 3-AGAGUCCAUGCAAAGCGGGGAUUGUACCUUU - 5' 16. Determine the amino acid sequence a ribosome would translate from the following non template DNA strand. (Hint: you must first convert the non template DNA strand to a template DNA strand and then to mRNAJ 3'-ACCTTGATCCTTGACGTATGTAGTATGTATC-5'
Unwinds DNA strand to make replication fork. Adds free nucleotides to the growing daughter DNA strands Adds short pieces of RNA to help DNA polymerase start Removes RNA and replaces with DNA Fuses or "glues" fragments of DNA together Proofreads or edits the DNA, checking for mistakes Given the following, DNA Sequence, what is the new daughter strand? (Did you label the 5' and 3' ends?) What is the name of the "fragments" of DNA on the lagging strand after...

6.) Vitamin C is an essential dietary vitamin for us because we cannot make it in our own bodies, the way that most animals can. This is because an important gene was inactivated by mutation in one of our ancestors millions of years ago. But vitamin C is not a protein. How can there be a gene to code for a molecule that is not a protein? (You may have to look some things up to answer this.) 7.) RNA...
Transcription is the process of rewriting DNA. DNA molecules are made from 4 different nucleotides which acts as building blocks. These building blocks are adenine, thymine, guanine and cytosine. When put together in different chemical combinations they become directions for the functions of the cell molecules which are primarily proteins. When a certain protein is needed, the RNA polymerase enzyme will find the gene for that particular protein and makes an RNA copy of it. DNA and RNA have similar...
