Chapter 16.6, Problem 1TQ
Summary Introduction

To review:

The usage of different industrial strains or species to express different forms of cloned products.

Introduction:

The characteristics and growth cycle of an industrial strain are known. The strain can be optimized according to the requirement. The industrial strain should possess some key properties such as genetic stability, easily manipulated, non-toxic, inexpensive, efficient gene expression, and the product should be ready for harvestation.

Expert Solution & Answer

Explanation of Solution

Different types of industrial strains possess distinct kinds of biochemical systems that favor various products. For instance, certain types of fungi naturally contain the complex mechanisms for the production of antibiotics. They also possess mechanisms to regulate the timing of switching on these pathways after the cell population has achieved a sufficient population density.

Bacterial cells such as Bacillus subtilis are highly predictable when it comes to their growth cycles. They do not pose much difficulty when manipulated in order to express the recombinant products such as human genes encoding several essential proteins. The bacterial cells multiply at a much faster rate and hence, the production of desired products can be achieved at maximum.

Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply.   Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.
When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.
