Answer:

The correct answer is - a. Nuclease activity and b. DNA methylaseDNA methylase.

Explanation:

The binding of the miRNA with the complementary DNA or mRNA sequence by either methylation of DNA, or by nuclease activity of the proteins, by the help of RISC complex as it brought them together In piRISCs complex. This complex goes and binds to the nucleotides to cause the silencing of the mRNA or the DNA sequence.

Thus, the correct answer is - a. Nuclease activity and b. DNA methylaseDNA methylase.

mash [69]
A eukaryotic cell is much more complex than a prokaryotic cell. Eukaryotic cells usually make up more complex organisms and have organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, a nucleus, and lysosomes. A prokaryotic cell only has circular chromosomes and is much smaller than a eukaryotic cell. Most single celled organisms are prokaryotes.

What is the process of chemosynthesis?
Angelina_Jolie [31]

Answer:

Explanation:

Define key words/vocab words to solve.

Sometimes you have to define words in the definition too :-P

chemosynthesis - the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.

maybe easier to understand below:

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.
