Answer:
what is the source of the chemical :bacteria/bacterial cells ?
why?:if a virus tries to attack the bacteria ,it uses restriction enzymes to fight it off .
.cleave foreign DNA,this eliminating infectious organisms..
EcoR1 restriction site
it is also part of the restriction modification system.In molecular biology it is used as a restriction enzyme .
why do we sometimes use multiple restriction enzymes?
..these enzymes cut both strand of the target DNA at different spots creating 3'-5' overhangs of 1 to 4 nucleotides.
to be able to clone a DNA insert into a cloning or expression vector ,both have to be treated with two restriction enzymes that create compatible ends.
what is the role of each of these chemicals in copying DNA?
primer
:is a short nucleic acid sequence that provides a starting point for DNA synthesis .this synthesis of a primer is necessary because the enzymes that synthesize DNA ,which are called DNA poly merases ,can only attack new DNA nucleotides to an existing strand of nucleotides .
tag polymerase:
Due to its key role in synthesizing and amplifying new strands of DNA ,Tag DNA Polymerase is essential to poly chain reaction PCR.
like other DNA polymerase can only produce DNA if it has primer,a short sequences of 20 nucloetides that provide a starting point for DNA synthesis.
nucleotides:
DNA is made up of a double helix of two complementary strands ,during replication ,these strands are separated .most prominently,DNA polymerase sythesizes the new strands by adding nucleotides that complement each strand .
DNA replication occurs during the S-Stage of interphase.
methods the separate pieces of DNA
.Gel electrophoresis is a technigue used to separate DNA fragments according to the size .
what pulls the pieces of DNA ?
DNA samples are loaded into wells at one end of a gel ,and an electric current is applied to pull them through gel.
why?
because all DNA fragments have the same amount of change per mass ,small fragments move through the gel.

Review the list of low-cost meals provided in the unit. What do they have in common? Explain. What low-cost, nutritious meals are you most likely to eat? Why? *Any help is very much appreciated!*
Answers
Let’s jump right in:
You’re older than you used to be.
For years, the elderly have been told not to expect anything from their bodies but decay and decrepitude. They can lift weights if they want, but they’re not going to get very strong and if anything they’ll just improve “tone” and “balance.” Well, that’s nonsense. The elderly absolutely can get stronger and even build muscle and improve their bone mineral density by lifting heavy things. Maybe not as easily as a 22 year old. Maybe not as much as when they were younger. But they can do it. There’s just one caveat: they need more protein than their younger counterparts.
The elderly aren’t as efficient at processing protein. To maintain nitrogen balance or tip the scales toward lean mass accrual, an older person is going to need more protein than a younger person – all else being equal. That goes for resistance training oldsters, puttering around the garden oldsters, and taking an hour to walk around the block oldsters. More protein is better than less.
You’re always hungry.
Of all the macronutrients, protein is the most satiating, and high-protein diets (which are usually also low-carb) consistently result in the greatest inadvertent reduction in calories. You don’t consciously stop eating. You’re not fighting your desire for food. You simply don’t want it. That’s the perfect antidote to insatiable hunger.
Just try it. Make a point to add an extra 20 grams of protein each meal. A few ounces of steak here, a chicken leg there, a piece of salmon, a few eggs. You’ll be fuller, faster.
So if your stomach resembles a bottomless pit, try increasing your protein intake.
You’re cutting calories.
Traditional calorie-restricted dieting certainly can help you lose body weight, but it also causes the loss of lean muscle mass. That explains why so many people who simply reduce calories to lose weight end up skinny-fat. Luckily, increasing the amount of protein you eat can offset some of the muscle loss caused by calorie restriction:
In weightlifters, a low-carb hypocaloric diet with 2x the RDA for protein resulted in greater nitrogen balance than a high-carb hypocaloric diet with RDA protein.
In women, a low-calorie, high-protein diet was better than a conventional high-carb, low-fat diet at promoting lean mass retention, even in the absence of exercise.
Under this plan, patients with certain diagnoses who are admitted to the hospitals are classified in one payment group.
