The rough endoplasmic reticulum (rough ER) is different from the smooth ER because A. the rough ER has lipids bound on its surface. B. aminoacyl-tRNA synthetases join amino acids to tRNAs on it. C. the rough ER has many ribosomes bound to it. D. smooth ER is coated by messenger RNAs. E. RNA polymerases are found all over the rough ER.
Which of these is not a response to ER stress? a. Expansion of the ER b. Upregulation of the gene encoding the translocon c. Inhibition of protein translation d. Increased expression of genes encoding molecular chaperones e. Apoptosis I think A and E are true, but I'm not sure about B-D
The ER for GE is 8.04% and the ER for AT&T is 13.38% while the SD for GE is 10.66% and the SD for AT&T is 6.41%. The CORR(GE,AT&T) equals -.11. The portfolio standard deviation of the combination of 80% in GE and 20% in AT&T is:
Please answer letter B!
1. (1.5 pts) Entering the ER: Translocation of proteins across the membrane of the ER is usually studied using microsomes (vesicles made from rough endoplasmic reticulum. Microsomes of the rough ER carry ribosomes attached to their outer surface. Translocation of proteins across the microsomal membrane can be assessed by several experimental criteria: (1) the newly synthesized protein is protected from added proteases, but not when detergents are present to solubilize the protecting lipid bilayer; (2) the...
covert the er diagram to a relational database schema
The following ER diagram represents ships. Ships are said to be sisters it they designed from the same plans. Convert the diagram to a relational database schema.
Question 4. ER model (5 points). You are asked to design the ER diagram for a database to manage data for athletes athletic game. Requirements are as follows: Each participating team has a name and a manager. Each athlete has a unique athlete ID, and is also described by first name and last name, gender and age. A team has many athletes but an athlete only belongs to one team. Each sport has a unique code and some sport name....
ER to Relational Mapping
a) i)
Reverse engineer the following schema to make an ER Diagram
A (),
B (),
C ()
B.a references A.a; C.ab references B.ab
ii)
EMP (,
ename, supervisor, Dno), DEP (,
dname)
EMP.Dno referencesDEP.Dno; EMP.supervisor references EMP.ssn
bold is underline.
Database specialist please help asap detailed
Q3. (1.5) You are given ER diagram. Transform ER diagram in to relational schema. 고2 Wo WP ES BN. CL
Part 1: Why do we need to create an E-ER model for an ER model? Explain the ‘overlap’ and ‘disjoint’ rules of E-ER model Part 2: You are creating a database for a college/university. Develop an E-ER Model with this given information: 1) Two specializations of Person: employee, student Person can be employee and/or student at the same time 2) Three specializations of Employee: staff, faculty, student assistant 3) Two specializations of Student: Graduate, undergraduate student Student...
FILL IN THE BLANK Soluble resident ER proteins that reach the Golgi are returned to the ER via ( ) -coated vesicles. The ER retention/retrieval signal, ( ), binds to a receptor in the Golgi lumen but falls off in the ER lumen due to a change in (. ), which affects the properties of the retention signal. Transmembrane proteins that are returned from Golgi to ER have a different signal,( ) , at the ( ) -terminal end of...
