A “polygene” or “multiple gene inheritance” is a member of a group on non-epistatic genes that interact additively to influence a phenotypic trait.
<span>jeremy's SUBSTANCIA NIGRA is producing less DOPAMINE than what it needs to.
Substancia nigra is a "black substance" located in the midbrain. When there is the death of dopaminergic neurons in the substantia nigra, the quantity of dopamine decreases, causing Parkinson symptoms. With time passing, the fewer neurons Jeramy will have and those symptoms will become more severe, that is the reason why is smoking more. The nicotine from cigarettes help modulate dopamine transmission and so, to reduce some symptoms.</span>
B. Because cells are in a different sense of living they can’t actually do activities.
Answer:
Explanation:
1- Capping occurs at the 5' end of mRNA.
2- The nucleside added is 7-methylguanosine.
3- The nuceloside is connected to the mRNA through a 5′ to 5′ triphosphate linkage.
4- The added nuceloside is modified by methylation at the nitrogen atom.
5- The mRNA is modified by methylation of ribose residues at the 2'-hydroxy position.
