Homework Answers
Monocistronic messenger RNA is the one which carries only one gene in it. Therefore during the process of translation, it uses only single reading frame so that it gives rise to single peptide sequence. If multiple reading frames will be used, then multiple peptide sequences will be formed and this occurs in polycistronic messenger RNA.
(Monocistronic messenger RNA carries single gene where polycistronic carries multiple genes. The former is present in eukaryotes and the latter is present in prokaryotes).
Please rate high.

The images below is DNA sequence (in reading frame) and the amino add translation far a region of a protein coding gene for two species you are researching. By comparing the two alignments and or using the translation table provided (remember U = T) mark all of the mutations in the DNA alignment as either non-synonymous (N) or synonymous (S). Place either an "N" or an "S" in the space above the mutation in the DNA alignment. How many non-synonymous...

What are the potential consequences of inaccurate mRNA splicing? a. A single base error at a splice junction will cause a large deletion. b. A single base error at a splice junction will cause a large inversion. c. A single base error at a splice junction will cause a large insertion. d. A single base error at a splice junction will change the reading frame and result in mRNA mistranslation.

3. Translation. According to the rules of the genetic code, there are six different reading frames in a double- stranded DNA molecule. One DNA strand serves as a template for transcription, which is complementary and antiparallel to the RNA product. The other DNA strand is the coding strand, which is identical in sequence to the RNA except for the substitution of uracil for thymine bases. A) There is a single open-reading frame (ORF) in the DNA molecule shown below. [Recall...
