Why would covalent bonds break in water? Why can they? - Because more stable or energetically favored bonds could be formed. They can break because the loss of energy by breaking hydrogen bonds in compensated for in the formation of new covalent bonds. Limitation to eukaryotic cells and photosynthesis - The sea slugs that live in symbiotic relationships with cyanobacteria or algae. The algae is not broken down or digested and absorbed into the slug's body. There is then a horizontal gene t...

Heterochromatin - Regions in chromosome where fibers are highly condensed Few genes - resistant to transcription by not completely exempt Concentrated in centromeres and telomeres What is a simple genome and which type of cell has one? - Codes for fewer proteins then a complex genome, prokaryotes Plant cell walls were.... - Reacquired after eukaryotes lost cell walls when they diverged from prokaryotes Genes - Regions of DNA transcribed into any type of RNA What are RNPs? Examples - Ribo...

eukaryotic cell types - animal - - nucleus - linear nuclear chromosomes - mitochondria - centrioles -- microtubule organizing center - no cell wall or capsule endosymbiosis - mitochondria and chloroplasts were prokaryotes that entered eukaryotic cells and became specialized to perform specific cellular instructions evidence for endosymbiosis - - organelles contain their own DNA (organelle genomes - organelles resemble present day prokaryotes - organelle genomic sequences resemble those...

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...
