Given the following mRNA, write the double-stranded DNA segment that served as the template. Indicate both the 5 and the 3 ends of both DNA strands. Also write out the tRNA anticodons and the amino acid sequence of the protein encoded by the mRNA message. DNA: mRNA: 5-CCGCAUGUUCAGUGGGCGUAAACACUGA-3 protein: tRNA:
Why would it be impossible for DNA splicing to occur utilizing the same mechanism as eukaryotic MRNA splicing? Spliced DNA could not be transcribed or translated DNA does not have a 3'-OH group for the initial nucleophilic attack that forms the lariat O DNA does not encode introns O DNA does not have a 2'-OH group for the initial nucleophilic attack that forms the lariat
The following segment of DNA is part of the RNA-coding sequence of a transcription unit. If the bottom strand is template, which of the following RNA sequences would be transcribed? DNA: 5-'ATAGGCGATGCCA-3' 3'-TATCCGCTACGGT-5' O 5'-UAUCCGCUACGGU-3' O 5'-ACCGUAGCGGAUA-3' O 5'-AUAGGCGAUGCCA-3' O 5'-UGGCAUCGCCUAU-3'
if the following DNA sequence were transcribed, which of the following describes the output of this process? 3'- TCTGGACA-5' A. This would produce a protein that looks like 5'- A G A C C U G U -3' B. This would produce a tRNA that looks like 3'- A G AC C U G U -5' C. This would produce an mRNA that looks like this: 5'- A G AC C U G U -3' D. This would produce an mRNA that looks like 3'- U C U G G A CA -5' E. This would produce another strand of DNA that 0ok like 5-AG ACCT GT-3. ..

EF-Ts factor regenerates EF-Tu/GDP from EF-Tu/GTP for the next round of elongation cycle in prokaryotic translation. The sigma subunit of RNA polymerase is replaced by NusA to recognise the promoter region of a gene. The -10 and -35 sequences in E. coli DNA are referred to as untranslated region. In human, translation begins before transcription of an mRNA completes. this statement true or false.
