Alternative rna splicing - Study guides, Class notes & Summaries

alternative splicing - - Splicing of introns in a pre-mRNA that occurs in different ways - leads to different mRNAs that code for different proteins - Increases the diversity of proteins. dna transcription vs replication - - replication synthesizes new (daughter) DNA - transcription of DNA forms RNA does the structure of the DNA (nucleosomes) impact the ability of the RNA polymerase to transcribe genes? - - yes - tightly bound nucleosomes, it's harder to get to the DNA so there is less e...

RNA polymerase - ANSWER pries the two strands of DNA apart and joins the RNA nucleotides as they base-pair along the DNA templates promoter - ANSWER DNA sequence where RNA polymerase attaches and initiates transcription Synthesis of RNA transcript - ANSWER initiation; elongation; termination synthesis of RNA transcript initiation - ANSWER after RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point of the template stra...

Penn Foster Biology Book 1 Questions And Answers Already Passed What is the difference between prokaryotic and eukaryotic cells in terms of genetic material? Prokaryotic cells have their genetic material free-floating in the cytoplasm, while eukaryotic cells have it enclosed within a nucleus. How do enzymes lower the activation energy of a reaction?

• DNA = phosphate + deoxyribose sugar + A/T/C/G o Contains two strands. The strands are antiparallel (opposite each other). o 5’ → 3’ 3’ ← 5’ • RNA = phosphate + ribose sugar + A/U/C/G o Single strand, can fold back onto itself and form pairs between itself (stem‐loop). • Each nucleic acid is made up of polymers (many monomers) that are called nucleotides. o Nucleotides contain one or more phosphates, a five‐carbon sugar, and a nitrogen base. o Nucleotides are alway...
