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:
Eukaryotic mRNA: usessnRNPs to cut out introns and seal together translatableexons. uses a spliceosome mechanism made of DNA to recognizeconsensus sequences to cut and splice. has a guanine cap on its 39 end and a poly(A) tail on its 59 end. is composed of adenine, thymine, guanine, and cytosine. codes the guanine cap and poly(A) tail from the DNAtemplate.
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

I've attached the table of transcription ans translation for a DNA and Bees work, Genes A and B are exons while C is an intron. Gene A has a silent mutation and Gene B has a nonsense mutation. Please answer the below for me The 3 genes code for different proteins: • Gene A = protein essential for stinger • Gene B = DNA replication enzyme • Gene C = fuzzy hair protein Do you think it matters which protein is mutated? Is one protein more important than another? How would you try to help the bees stay healthy using the information from the mutations?
