Answer:
Option C. Dicer
Explanation:
Dicer is a dsRNA endoribonuclease like bacterial Class III RNaseIII that is encoded by the DICER1 gene contains a N-terminal ATP-subordinate RNA helicase motif or domain.
Dicer cuts or cleaves precursor RNA molecules to make miRNA molecules. MicroRNAs regulates gene expression by hindering the procedure of protein creation. In the initial step of making a protein from a gene, another sort of RNA called RNA (mRNA) is made and goes about as the plan for protein production.
False. Oxygen is absorbed in the alveoli sacs of the lungs.
Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.
Answer:
A.
Explanation:
Because the trait undergoes a secondary loss; it has been there but it doesn't always appear in all generations.
<span>Yes, both prokaryotes and eukaryotes have liquid cytoplasm in their construction. To the best of my knowledge, AT LEAST MOST viruses do as well, if not all. However, their cell structures are relatively primitive and their cytoplasm is viscous and granular.</span>
Answer: What is the defining characteristic of eukaryotic cells? Put these in your own words.
Eukaryotic cells are defined by the presence of a nucleus containing the DNA genome and bound by a nuclear membrane (or nuclear envelope) composed of two lipid bilayers that regulate transport of materials into and out of the nucleus through nuclear pores.
What types of organisms have eukaryotic cells?
There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
