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.
cells are not the smallest unit of life because atoms are smaller than cells
Answer:
0,58
Explanation:
Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).
Plant like Protists - also called algae - autotrophs
<span>Fungus like Protists - heterotrophs, decomposers, external digestion </span>
<span>From the above their role in the aquatic food chain is clear . </span>
<span>They perform their role as </span>
<span>1) producers = example = Plant like Protists - also called algae - autotrophs </span>
<span>2 ) consumers = example =Animal like Protists - also called protozoa (means "first animal") - heterotrophs </span>
<span>and </span>
<span>3) Decomosers = example ==Fungus like Protists - heterotrophs, decomposers, external digestion
