- The primary RNA transcript of the chicken ovalbumin gene is 7700 nucleotides long, but the mature mRNA that is translated on the ribosome is 1872 nucleotides long. This size difference occurs primarily as a result of: capping cleavage of polycistronic mRNA removal of poly A tails reverse transcription splicingA _____________ is a purine-rich sequence in close proximity to AUG on a prokaryotic mRNA that binds to a complementary sequence on the 30S ribosome subunits, thereby promoting the formation of the correct preinitiation complex.Draw a pre-mRNA with at least 4 exons and 3 introns and draw two possible mature mRNAs that can result from alternative splicing of this RNA.
- Aminoacyl-tRNA synthetases are the only component of gene expression that decodes the genetic code. Explain.. Eucaryotic processing of hnRNA into mature mRNA includes all of the following steps except: ribosome attachment to the Shine-Dalgarno sequence 5’-addition of a 7-methylguanosine cap 3’-addition of a polyadenylated tail splicing together of exons excision of intronswhat is the difference between leader mRNA and attenuator sequence?

What consequence for this peptide does the substitution of the uracil at position 28 of the mRNA with guanine have? GGUUGAAUGGAACAACGCGUGCACCCUUAGAGGUAACCCUCC | G Group of answer choices No consequence, it is a silent mutation. It shortens the peptide by two amino acids. It destroys the start codon of the peptide coding region. It extends the peptide by two amino acid. It replaces one of the original amino acids of the protein with a different one.The following is the only intron sequence of a gene that will be excised during the maturation of the mRNA. But it is not spliced in some tissues, where alternative splicing pattern is seen. Will the amino acid of its protein product following this sequence change? Explain with an example.

- Hemophilia in the Russian royal family was caused by defective protein involved in blood clotting (factor IX). This defective protein was caused by a mutation that altered the splicing of the exons. This genetic change in the splicing pattern created a new stop codon in the mRNA for factor IX. Give an example of how a mutation that altered the splicing sites in the pre-mRNA might lead to a premature stop codon in the gene.. Eukaryotic processing of hnRNA into mature mRNA includes all of the following steps except: ribosome attachment of methionine to the 5’-AUG-3’ codon 5’-addition of a 7-methylguanosine cap 3’-addition of a polyadenylated tail splicing together of exons excision of intronsThe following is the only intron sequence of a gene that will be excised during the maturation of the mRNA.
