Compare the tumor suppressor properties of Rb with BRCA2 protein, giving molecular details of each of the interactions that you mention with a detailed diagram. (2-3 paragraphs, with a diagram showing how Rb and BRCA2 interact in a molecular pathway).
A tumor suppressor gene is a gene that prevents cancer development. It has been reported that mutations on these kind of gene could lead to cancer laking their function. Tumor suppressor genes has 3 main functions, such as:
The retinoblastoma protein (pRb) is encoded by the tumor suppressor gene, Rb. Its main function is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide, once the cell is ready, Rb is able to phosphorylate the pRB leading to Its inactivation.

BRCA2 is a human gene which encode BRCA2 protein. The main function of this protein is to repair damaged DNA or destroy cells when DNA can not be repaired. BRCA2 binds to the single strand DNA interacting with the recombinase RAD51 leading to the stimulation and maintaining strand invasion.

Carl has just finished purifying a protein and analysis by gel filtration indicated that the molecular weight of the native (undenatured) protein was 130,000 dalton. His advisor wanted him to determine whether this protein had quaternary structure using gel electrophoresis. He wants to be able to describe the molecular weight of each of the subunits and the forces involved in linking these subunits together (disulfide linkages and/or electrostatic, hydrogen bonding and hydrophobic interactions). Carl first analyzed his pure protein sample...
Molecular Bio lab. HELP!!
Here is the first part: the sequence traces and the entire
sequence. i just need the last 3 tasks. i color coded the ends so
you can see where it overlaps and connects
In the files section for your group there is a simulated output from an automated DNA sequencer using a variation of the classic Sanger method. (If you want to print it, it is formatted for legal sized paper.) This sequence encodes a protein...
1.) Describe the goals of a Gel Filtration Chromotography
Experiment???
2.) Explain each key theoretical principle of a Gel Filtration
Chromotography, and how they help acheive the goal???.
4.) Explain the key equations used in the Gel Filtration
Chromotography experiment and the terms involved in the
equation????
HI im trying to prepare for a lab/report and i have some
questions i could use help with please :) over all having trouble
seeing how everything ties together etc :) thank you...
2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...

Using the book, write another paragraph or two: write 170
words:
Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
