Hydroxyl groups make sugars more water soluble. Your answer is B
Answer:
Potential targets:
1- DNA methyltransferases
2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.
3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.
Explanation:
Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.
Answer:
B. The bird will stop flying because it will quickly use up its remaining
energy.
Explanation:
This is because the mitochondria is known as the power house of cells. Oxidative phosphorylation takes place in this organelle and it involves the conversion of ADP to ATP through the hydrogen ions(protons).
When the hydrogen ion channel is blocked, energy production in cells stop.
This is why the bird will stop flying as it would have used up its remaining energy and won’t have a new one to use to continue flying.
Away from the ganglion The axon of a
ganglionic neuron is called a postganglionic fiber because it carries impulses.
an accumulation of extracellular fibrillar proteins and abnormal
dendrites and axons. A “ganglion”
is essentially a living relay. The inputs are “pre-ganglionic” and the outputs
are “post-gangionic.” Simple.
