HELPING TAGS: Biology, developmental biology, plants, actin filaments
Can non-motile cells, such as plants, benefit from actin filaments' motion-related functions? Explain your answer.
Will UPVOTE, just pls help me answer the question. Thanks.
Step by step
Solved in 2 steps
- Dynamic instability causes microtubules either to grow or to shrink rapidly. Consider an individual microtubule that is in its shrinking phase. What would need to happen at the end of the microtubule in order for it to stop shrinking and to start growing again? Be specific! What would happen if only GDP, but no GTP, were present in the solution? What would happen if the solution contained an analog of GTP that cannot be hydrolyzed?Q. What is meant by dynamic instability (e.g. of microtubule filaments)? include how the binding of subunits to nucleotides impacts the stability and/or growth of filaments.Need help. Contrast DNA replication with gene expression (transcription→translation)—when does each occur? What molecules are involved? How much of the DNA is utilized?
- QUESTION :-Why is it important to validate cell research with translational potential in animal and human studies? a. Cell cultures are often transformed and may no longer function in a physiological manner. b.Humans are complex systems and may not behave in the same way as a single cell. c. Genetic and epigenetic variation in the population may impact the findings. d.All of the aboveMultipass transmembrane proteins synthesized by ribosomes on the rough endoplasmic reticulum generally have which of the following arrangements of start-transfer and stop-transfer signals? multiple start signals and multiple stop signals (to allow multiple transmembrane regions) multiple start signals, but only one stop signal (to allow only one transmembrane region) only one start signal, but multiple stop signals (to allow only one transmembrane region) only one start signal, and only one stop signal (to allow only one transmembrane region) only one stop signal, and only one start signal (to allow only one transmembrane region)IDENTIFICATION. HELLO, BASED ON MY PRPEVIOUS EXPERIENCE HERE, BARTLEBY EXPERTS CAN ANSWER UP TO 3 SUBPARTS. THANK YOU Identification. a)Carrier of the activated amino acids to the ribosomes for incorporation into the growing peptide chain. b)Molecule that attaches to myosin and actin during muscle contraction.
- Descrive in 2-3 sentences an in vitro experiment that differentiates between the Arp2/3 complex’ ability to associate with both the side of the ‘mother’ actin filament and with the barbed end of the ‘mother’ actin filament. Your experiment should take advantage of capping protein (binds and blocks barbed ends), and direct visualization of actin filaments.Question:- Regarding how information is passed through the cell, why is the state (confirmation) of a cell changed when other molecules are added or removed?Important roles and functions of Microtubule-Associated Proteins (MAPs) *** for increase in stability and for the promotion of stability? to increase binding capacity of the motor proteins to associate the subunits with the corresponding motor proteins for the phosphorylation of the plus ends of the microtubule
- Question:- Distinguish between two possible import mechanisms: biased diffusion and force‐generating motors.Question:- Describe the path a cell surface receptor will take when being synthesized (starting at the beginning of translation) to its expression on the plasma membrane; indicate the orientation of the receptor and any other processing that is undergoes. Describe the different possible fates of a receptor once it is internalized by receptor-mediated endocytosis.WHAT IF? Imagine a protein that functions in the ERbut requires modification in the Golgi apparatus beforeit can achieve that function. Describe the protein’s paththrough the cell, starting with the mRNA molecule thatspecifies the protein.
