Scientists know that a mutation - or alteration - in a particular gene's DNA may contribute to a certain disease. However, it can be very difficult to develop a test to detect these mutations, because most large genes have many regions where mutations can occur. For example, researchers believe that mutations in the genes BRCA1 and BRCA2 cause as many as 60 percent of all cases of hereditary breast and ovarian cancers. But there is not one specific mutation responsible for all of these cases. Researchers have already discovered over 800 different mutations in BRCA1 alone.
The DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes like BRCA1and BRCA2. The chip consists of a small glass plate encased in plastic. Some companies manufacture microarrays using methods similar to those used to make computer microchips. On the surface, each chip contains thousands of short, synthetic, single-stranded DNA sequences, which together add up to the normal gene in question, and to variants (mutations) of that gene that have been found in the human population.
Answer: Direct sunlight is more concentrated heat, which tends to be warmer but also covers a smaller surface area. During the winter months, the Sun is lower in the sky and its rays strike the Earth at an oblique angle, otherwise known as indirect sunlight.
