Two well-understood sncRNAs in eukaryotic cells are: microRNA and siRNA. SncRNAs are small non-coding RNAs with the main function in the regulation of different stages in gene expression. micro RNA are involved in RNA silencing (negative gene expression) and post-transcriptional regulation of gene expression(microRNA is complementary to a part of mRNA and can inhibit translation of that mRNA). siRNAs also <span>called</span> silencing RNA because of their possibility to inhibit translation by degrading mRNA after transcription.
Answer:
Epidermolysis bullosa (EB) is a group of connective tissue disorders that causes skin to be fragile and blister and tear easily. Blisters and sores occur when clothing rubs on skin or when the skin is bumped. Mild cases of the disease usually cause painful blisters on the hands, elbows, knees, and feet.

<span>The Radio-ulna and digits of most primates and animals represents a homologous structure
An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>

Answer :
When lava pushes the crust upward but hardens before erupting onto the surface, dome mountains are formed. The wind and rain pummel the domes, carving up peaks and valleys.
