Answer:
f. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where one strand is already methylated and thus correctly methylated daughter strands after replication.
Explanation:
DNA methylation is the addition of methyl group to DNA.it is an example of EPIGENTICS mechanism in genetics( epigentic refers to modification of expression of genes instead of altering the gene codes),
The objective of this mechanism is to modify the function of the particular GENE, therefore affecting the expression of the gene,
Well, the question is confusing, since White is the recessive (ususally) and red being Dominant. It would be like
RR, for all red, and
WW, for all white, or perhaps rr
Answer:Red Flower RR, White flower rr/WW
Answer:
Correct
Explanation:
The statement is correct because, during the chemical synapses, the transmission of information takes place when the presynaptic neuron releases a <u>neurotransmitter</u> that binds to a specific receptor located in the postsynaptic membrane. The release of these neurotransmitters happens almost always when the action potential reaches the synaptic terminal. In the membrane of the synaptic terminal, the number of Ca++ voltage-depended channels is greater than in other parts of the membrane, hence, when the action potential depolarized the membrane, the channels open and the Ca++ defuses actively into the cell. The intracellular concentration of Ca++ is very high and this strong and rapid increase, facilities the depolarization of the membrane and <u>allows the release of the neurotransmitter to the postsynaptic membrane</u>.
