What cell has domains protist, fungi, animals,and plants ? Eukaryotic What basic features do all cells have ? -plasma membrane -semiflud substance called cyotsol or cytoplasm -DNA or Chromosomes (carry genes) -ribosomes (make proteins) Prokaryotic cells are characterized as NOT having -no nucleus -no membrane bound organelles What unbound region in DNA found in prokaryotic cells? nucleoid - this is where chromosome is found In prokaryotic cells, the cytoplasm is bound by what? plasm...

The -10 and -35 regions of prokaryotic promoters are called consensus sequences because ________. they are similar in all bacterial species Which feature of promoters can be found in both prokaryotes and eukaryotes? TATA box What transcripts will be most affected by low levels of α-amanitin? pre-mRNAs How do enhancers and promoters differ? Enhancers increase the efficiency of gene expression, but are not essential for transcription. Promoter recognition is essential to transcription in...

Protein kinases are enzymes that transfer the terminal phosphate from ATP to an amino acid residue on the target protein. Many are located on the plasma membrane as integral membrane proteins or peripheral membrane proteins. What purpose may be served by their plasma membrane localization - -They can more readily encounter and phosphorylate other membrane proteins -Which of the following statements is a logical consequence of the second law of thermodynamics - -Every chemical reaction must ...

What separates the living cell from its surroundings - -Plasma membrane -What plasma membrane exhibits BLANK, which allows some substances to cross it more easily than others - -Selective permeability -What are the most abundant lipids in most membranes - -Phospholipids -Phospholipids are ___, containing hydrophobic and hydrophilic regions - -Amphipathic molecules -What type of proteins penetrate the hydrophobic interior of the lipid bilayer - -Integral proteins -What type of prot...

Muscle cells differ from nerve cells mainly because: - -they express different genes -Cell differentiation always involves: - -the production of tissue-specific proteins -Apoptosis does not involve? - -lysis of the cell -Absence of bicoid mRNA from Drosophila egg leads to the absence of anterior larval body parts and mirror-image duplication of posterior parts. This is evidence that the product of the bicoid gene - -normally leads to the formation of head structures -Proto-oncogenes ...
