Question
Choose from the following to answer questions 5 and 6. A) BLAST or Basic Local Alignment Search Tool B) Mass spectrometry C) Transcriptomics D) Multiple sequence alignment E) PubMed S. A scientist has recently sequenced a gene and she is interested in knowing whether it is to also present in other organisms. She would start by searching GenBank with identify homologs 6. Having determined that indeed homologs of the gene are present in GenBank, the next to obtain published literature on the gene of interest. logical step is to search 7. The S'-end of a polynucleotide chain contains the chemical group A) Amino group B) Carboxyl group C) Hydroxyl group D) Carbonyl group E) Phosphate group 8. The RNA polymerase binds to which region of prokaryotic genes to initiate transcription? A) Operator sequence B) Termination signal C) Promoter D) Poly A tail E) Enhancer region 9. DNA polymerases do not initiate DNA synthesis de novo, i.e., without a priming end. -, which is later Priming in vivo is achieved by synthesis of a short fragment of removed by the activity of DNA polymerase I in prokaryotes. A) RNA, 5' to 3' exonuclease B) DNA, 3' to 5' exonuclease C) Protein, 5" to 3'endonuclease D) RNA, 3' to 5' endonucleaseExplanation / Answer
5 ans- BLAST or basic local alignment search tool
BLAST are used for finds regions of local similarity between sequences, comparing gene and protein sequences against others in public database.
6 ans-pubmed
It's a free search engine that uses a sophisticated indexing system, by this over 15 million biomedical journal obtain.
7 ans-phosphate group
The the phosphate group attaches to the sugar's fifth carbon.
8 ans-promoter
Transcription starts at promoters on the DNA, Usually located upstream of the gene or genes to be transcribe.
