What is the biological significance of having two different types of terminators in transcription? Transcription in prokaryotes is terminated by factors called rho-dependent and rho-independent terminators; Rho is a ring-shaped protein and is the main factor required for termination (Leland, 2010). The rho-dependent and rho-independent terminators play a major role in the separation of an RNA transcript from the DNA template which signifies the end of transcription. However, the exact process is not completely understood yet. The rho-independent terminator is typically encoded in the genome and is positioned downstream from the stop codon. There is definitely a difference in structure between the two terminators; rho-independent terminators contain an inverted and repeated sequence which is able to form a hairpin structure and I will discuss the structure of a rho-dependent terminator shortly. The sequence within the loop in the rho-independent terminator is partly species specific. For example, the hairpin loops in E. Coli may contain the sequence GAAA or TTCG while the sequence in other species like B. subtilis may be TTT or AAAA to name a few. This may deduce one reason why we have two different terminators in transcriptions; in order to account for the magnitude of the number of species on Earth, especially in the prokaryote section. On the other hand, rho-dependent terminators were first learned about in bacteriophage genomes and are widespread in the bacteria species. The mechanism for the rho-independent terminator to end transcription occurs when the separation of the transcriptional elongation complex is more beneficial than continuing, largely due to the increasing instability (Ciampi, 2006). These types of terminators can be found at the ends of genes and they play a significant role in controlling gene expression. For example, there exists a rho-dependent terminator that is involved in the expression of the damaging tryptophanase (tna) operon of E.
* Reduce the risk of supplier failure or uncertainty-safety and buffer stocks are held to provide some protection against such contingencies as strikes, transport breakdowns due to floods or snow, crop failures, wars and similar factors
* Protect against lead time uncertainties such as where suppliers’s replenishment and lead times are not known with certainty-in such cases an investment in safety stocks is necessary if customer service is to be maintained at acceptable levels….
Identifying Dependent and Independent Variables
Instructions: For each of the following research designs, identify the dependent and independent variables.
1. To investigate the effects of exercise on mathematical problem-solving ability, a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising, both groups did a set of math problems.
2. A researcher hypothesized that talking to plants enhances their growth. To test her hypothesis….

Q. What are the main dependent and independent factors that are being studied in this theory? If possible, try to graphically illustrate the proposed relations between these factors
Before discussing the main dependent and independent factors of critical realism theory, we need to know what the terms ‘dependent factors’ and ‘independent factors’ mean. The independent factor is typically the variable representing the value being manipulated or changed and the dependent factor is the observed result….
is opened you can secure the lid on the chamber and insert the sensors into the holes that you previously made. After 15-minutes of data being collected you can observe the data. Now that you have completed the light independent reaction, you can begin by setting up the light dependent reaction. First, assemble the lamp without turning it on until told to do so. Remove the aluminum foil and align the bottom of the chamber with turgid spinach leaves. Re-secure the lid on the chamber and connect the….
on the demand pattern, which creates the need for inventory. The two types of demand are Independent Demand and Dependent Demand for inventories. The choice of how to control inventory depends upon the fact of whether or not the demand of the items has a dependent or an independent character.
This difference is important in selecting an adequate inventory management approach.
Independent demand exists where the rate of use for an item does not relate directly to the use of another….

1. Why do you want to be a Rho Gamma and what characteristics do you embody that are relevant to this position?
I want to be a Rho Gamma because I feel like it is a good way to change the lives of a group of individuals in a big way. I think that being there for these New Members in the Greek Community. I think some characteristics I have that would help me in this position would be organized, hardworking, passionate about learning new things but also making new experience to better not only myself….
