aligned to Hs.bio.2.a Use A Model To Describe The Structure And Sequence Of Dna, Including Nucleotide Structure, Base Pairing, And The Structure Of The Helix. Hs.bio.2.b Obtain And Evaluate Information To Explore Additional Functions And Regulatory Roles Of Rna, Dna, And Protein, Including Their Roles In Gene Expression And Cellular Differentiation. Examples: Rna Contributing To Ribosome Structure, Histone Modification Altering Chromatin Structure, And Transcription Factors And Non-coding Dna Involved In Nuclear Regulatory Functions. Clarification: Discussion Should Include Proteins That Regulate And Carry Out Essential Functions Of Life Including Enzymes, Structural Proteins, Hormones, And Receptors. Hs.bio.2.c Obtain, Evaluate, And Communicate Information Regarding How Dna And Genetic Technology Apply To Daily Life. Examples: Crispr Can Be Used To Develop Species-specific Pest Control Tools. Gmo Technology Is Used To Produce Drought-resistant Plants To Increase Food Supplies. Genetic Screening Is Used In Neonatal Healthcare.

A template strand of DNA has the sequence 3'-TCAG-5'. What is the sequence of the mRNA molecule transcribed from this DNA? During transcription, if RNA polymerase encounters the DNA sequence 5'-GCTA-3' on the template strand, what corresponding sequence will be present on the newly synthesized mRNA molecule?
