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>
Answer:
As image is not provided,let's discuss about ecological succession.
Explanation:
Ecological succession can be described as the development of a community from its pioneer to climax community. There are two types of ecological succession:
Primary ecological succession: This type of succession occurs in lands where there was no life before or in lands where signs of life have completely been removed like an lava eruption. The rocks in this land are broken down and slowly, pioneer species begin to grow.
Secondary Succession: This type of succession arises after a natural disaster like fire etc or after any human activity has wiped out the previous community which survived on this land. smalls shrubs and grass starts to grow back on this land, which is replaced by the intermediate species and finally with the climax community.
