The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
The most strict policy regarding waste management in our area is segregation. Waste materials must be segregated according to their class. It's a strict policy since garbage will not be collected if they are not segregated. This is effective because it allows for the easy reuse and recycle of materials.
Answer:
- <em>The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.</em>
- <em> Carbon is found in all organic compounds, but that doesn't mean that all compounds that contain carbon are organic.</em>
- <em>Nitrogen in the reduced form is the major component of the three most important biological macromolecular structures: (i) proteins/polypeptides, (ii) DNA and RNA, and (iii) polymers of amino sugars.</em>
- <em>Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.</em>

An element is made up of only one type of atom.
Answer:
duplicate their chromosomal DNA prior to nuclear division
Explanation:
Mitosis and meiosis both involve duplication of a cell's DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells.
