So there is something known as CAS-9 or Crispr. Its actually been getting a lot of attention lately because of how it works and its potential uses.
When we look at DNA, it must be very precise. One messup and it can cause huge problems.
If an organism was to contract a virus, the virus would try and make its own DNA to infect other cells.
However, if the organism somehow beats the virus, it stores a copy of the DNA structure of that virus in Crispr.
CAS-9 will then search through every strand of DNA and will get rid of any DNA that exactly matches that one piece they have copied.
This answer goes in depth buts it very interesting actually and it is gaining lots of attention.
Answer: c) biologists would track the number of species and their relative abundance in the gulf coast region in 2009, 2010, and 2011
<span>(4) active transport
</span>Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e. moving from an area of lower concentration to an area of higher concentration.
To contract and churn the food to break it down into smaller molecules
Gene. A segment of a DNA molecule that codes for a particular protein and determines the traits of the individual. A gene is the basic unit of heredity in a living organism
Hope it helps!
