DNA and RNA

DNA and RNA are two different nucleic acids found in the cells of every living organism. Both have significant roles to play in cell biology. DNA and RNA structure are similar because they both consist of long chains of nucleotide units. However, there are a few structural details that distinguish them from each other, and if you are to compare DNA and RNA, these would be the results:

RNA is single-stranded while DNA is a double-stranded helix. RNA also has uracil as its base while the DNA base is thymine. However, even with the differences in their structures, DNA and RNA have cooperating roles in the field of Cell Biology.

DNA contains the genetic information of an organism, and this information dictates how the body’s cells would construct new proteins according to the genetic code of the organism. Within the cell structure, DNA is organized into structures called chromosomes, which are duplicated during cell division.

These chromosomes would then release the genetic codes that will be transcribed and carried by the RNA (specifically the messenger RNA) to the ribosome. The ribosome will then synthesize new proteins that will help the body grow. This is the how the DNA and RNA work together in the body.

What is DNA?

Deoxyribose Nucleic acid (DNA) is a nucleic acid present in the cells of all living organisms. It is often referred to as the “building blocks of life,” since DNA encodes the genetic material which determines what an organism will develop into. In addition to maintaining the genetic blueprints for its parent organism, DNA also performs a number of other functions which are critical to life.

This nucleic acid was first identified in 1889, when researcher Friedrich Miescher found a substance he called “nuclein” in human cells. In the early 20th century, several researchers including Phoebus Levene and William Astbury performed additional research on nuclein, beginning to understand its components, structure, and role in life.

Each DNA molecule consists of two long strands that are wrapped around each other. Because of this, the DNA structure resembles a double spiral “staircase” or a helix.

Each rung of the DNA ladder is composed of two substances, known as bases, which lock together. All in all, there are four different types of bases, and together they create four different kinds of rungs. The exact DNA sequencing of these rungs makes up a cell’s chemical information. This DNA information is vital since it shapes the cell’s development and regulates every single detail of how a cell should work. DNA contains chemical information known as genes. These genes are individual instructions in the code that tells the body’s cells how to produce new proteins.

Fact About Green Tea


Green tea has gained popularity as having an effect on weight loss. It is well known for its polyphenol and antioxidant components that may have a positive effect on cancer and aging.
Green tea may boost the weight loss process by boosting the body's exercise endurance, causing it to burn more fat to build leaner muscle. Over time, consistent servings of green tea may help maintain the desired weight levels, as it acts as a dietary aid to maintain a healthy metabolism. Since green tea does not have any known side effects, it can be enjoyed in the desired quantity on a daily basis.
1. Function
In addition to its fat-melting properties, green tea may also stop the absorption of fat from food into the body. Green tea suppresses the appetite and helps to regulate blood sugar levels, both of which are effective for weight loss.
2. Considerations
The combination of epigallocatechin gallate (EGCG) and caffeine may give green tea its effective fat-burning and calorie-burning properties. Caffeine taken alone, or in other beverages, does not result in the same level of weight loss effectiveness as it does with green tea, however.
3. Identification
Green tea, also known as Camellia sinesis, is native to East Asia, yet it is cultivated in other parts of Asia, as well as Africa and the Middle East. Green tea is especially enjoyed in Japan, China, Thailand and India, where it is drank as a leisure tea and for medicinal benefit. Green tea is used in the traditional medicine of China and India for digestion, mental health, wound healing, as a diuretic and stimulant, and for blood sugar and temperature regulation.
4. Expert Insight
Research conducted by the Tang Center for Herbal Medical Research at the University of Chicago showed that the green tea component EGCG (epigallocatechin gallate) has a positive lowering effect on levels of cholesterol, lipids and glucose in the body. The study showed that EGCG reduced the skin's fat deposits, as well as the fat stores within the abdomen. On the other hand, the research conducted by the American Journal of Clinical Nutrition showed that green tea has an effect on the body's metabolism through its promotion of thermogenesis, or calorie burning, in the body. This, coupled with fat oxidation, makes green tea a preferred natural agent for weight loss.

Fat Burner Green Tea | Green Tea Fat Burner

Fat burner green tea is widely used as an ingredient in dietary supplements. There are many uses for Green Tea such as the fact that several people drink an infusion of leaves as a health tonic.
Green Tea Fat burners are prepared with dried leaves, which are not fermented to ensure minimal oxidation while this natural product is processed. Diet supplements also include Green Tea in their formulation, because it helps in weight loss, but also prevents free radical damage, that usually occurs from pollution and sun exposure.
Apart from aiding with weight loss, this tea soothes irritated skin and is an effective anti-inflammatory and anti-bacterial agent. fat burner green tea is also rich in polyphenols, vitamins C, E and antioxidants 200 times more than vitamin alone.
Another benefit of Fat Burner Green Tea is the complementary protection to weight loss programs, since it was found that this herb prevents the absorption of fat from intestines, protecting the digestive system and preventing respiratory infections.
As an herbal extract, Green Tea Fat Burner of Chinese origin contains 50% of polyphenols, renowned antioxidants recommended to people who are following a weight loss diet.
Because this is an herbal treatment, for the more secure you can visit a health care provider to help determine the dose that works for you in your weight loss treatment.
