Answer:
TTGAGCCTA
Explanation:
A is paired with T and C is paired with G, so switch each gene with it opposite
DNA replication occurs in the 5 prime (5') to 3 prime (3') direction.
I'm sure you've heard this many times. I tutor in genetics, and all of my students can rattle that off. Less understand what it means.
First, understanding what 5' and 3' mean is important. DNA is composed of a ribose sugar, a phosphate group, and a base (A,T,G,C). The sugar has a phosphate group attached to its fifth carbon, and a hydroxyl group on its 3rd carbon. Nucleotides (separate components of DNA) are linked by the phosphate group and the hydroxyl group. So, every nucleotide is linked at the phosphate group and the hydroxyl group besides two - the two nucleotides at either end of the strand of DNA. The one that leaves a phosphate group exposed is called the 5' end of DNA, and the one that leaves a hydroxyl group exposed is called the 3' end of DNA.
<span>A problem with many students just memorizing that replication occurs in the 5' to 3' direction is that there are two strands of DNA involved in replication. DNA polymerase (the major enzyme responsible for replication) reads the already existing strand of DNA in the 3' to 5' direction, and creates the new strand of DNA in the 5' to 3' direction (meaning that it adds nucleotides to the 3' end of the new strand).</span>

Explanation:
Answer:
Not being able to adapt creates competition from those who can adapt. This is called the survival of the fittest. New predators and loss of habitats create environmental pressures that can limit the growth of a population and lead them to extinction if they are unable to adapt. The faster the change occurs, and the more drastic the change is with respect to the way that species lives, the more likely it is that the species will not be able to adapt in time and may disappear. This is also called Natural selection.
