- There are two ways in which rearrangement of domain- encoding gene segments can result in novel protein functions. Which of the following is NOT included? Domain shuffling Domain duplication Domain replication Domain substitution Which of the following features are NOT shared by prokaryotic and eukaryotic cells? shared metabolic pathways similar mechanism for synthesizing and inserting membrane proteins plasma membrane of similar structure nucleosomes of similar constructionDescribe in general terms the histone code hypothesisExplain the function of spliceosomes in eukaryotic cells. The following sequence represents pre-mRNA derived from a gene coding for alpha keratin in birds. Label the sequence to show potential exon(s), intron(s) and spliceosome cut site(s). That is, put the intron(s) sequences in parentheses and use black slash symbols (/) to indicate the spliceosome cut site(s). What is the sequence of the mature MRNA after splicing?

- Genetic expression involves transcription and translation. Match the structure or molecule to the step site where amino acid combines with tRNA intron sequences are removed and exons are combined together makes RNA more stable in the cytoplasm region of DNA with sequences that combine with RNA polymerase transcribed strand that will go on to translation connects amino acid to polypeptide chain and leaves tRNA site where tRNA with amino acid enters the ribosome recognized by the protein synthesis machinery enzyme that connects RNA nucleotides to DNA template part of tRNA with nucleotides complementary to mRNA 1. peptide bond 2. 3. antisense strand 4. anticodon loop 5.
