Palindromes. A palindrome is a sequence of letters and/or words, that reads the same forwards and backwards.  able was I ere I saw elba  is a palindrome. Palindromes also occur in DNA.There are two types.. Palindromes that occur on opposite strands of the same section of DNA helix. 5' GGCC 3' 3' CCGG 5'. This type of palindrome serves as the target for most restriction enzymes. The graphic shows the palindromic sequences seen by five restriction enzymes (named in blue) commonly used in recombinant DNA work.
The Dietary Guidelines for Americans recommends that carbohydrates make up 45 to 65 percent of your total daily calories. So, if you get 2,000 calories a day, between 900 and 1,300 calories should be from carbohydrates. That translates to between 225 and 325 grams of carbohydrates a day. You can find the carbohydrate content of packaged foods on the Nutrition Facts label. The label shows total carbohydrates â which includes starches, fiber, sugar alcohols, and naturally occurring and added sugars.
The recommended intake is a minimum of 130 grams/day, or 45 - 65 percent of daily calories for adults, independent of age or activity level. This is the minimum needed for your brain to function. Athletes are recommended to consume 6 - 10 grams for every kilogram of body weight per day.For example, a typical man weighing 70 kilograms needs 420 grams of carbs per day to fuel his activity.If you are on a low-calorie diet (less than 2000 calories per day), it may be difficult to achieve the 6 grams per day.ince there are four calories per one gram of carbohydrate, you would need to be consuming 250-300 grams of carbohydrates per day. The digestibility of the carbohydrates you consume (fiber content) plays a role in the physiological energy available.
