The label on a bag of salt-free pretzels indicates that they chips are "low-fat." this means the pretzels provide _____ gram(s)
Brilliant_brown [7]

3

The label on a bag of salt-free pretzels indicates that their chips are "low-fat." this means the pretzels provide 3 gram(s) of fat or less per serving.

Low-fat diets are diets in which the fats are reduced. Low-fat diets are produced in order to prevent diseases such as obesity and heart diseases. Food manufacturers usually use nutrient claims such as '‘low fat’' to indicate the nutritional value of their products. A ‘low fat’ food contains not more than 3g of fat per 100g of food  (for solids) and not more than 1.5g fat per 100g (for liquids).

A scientist wants to begin making a DNA fingerprint, but she has only a very small DNA sample. What should her next step be
azamat

For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.

Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-

1. Denaturation of the double-stranded DNA (at around 95°C)

2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)

3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).

With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.
