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 Electrons would need to be in a covalent bond. Covalent means that the electrons are equally shared between atoms.

Answer:
Option A
Explanation:
The genotypic frequency for tt (q²) = 36% = 36/100 = 0.36
To calculate for the allelic frequency of t which is q, we have to find the square root of q² to do this. Thus
√q² = √0.36 = 0.6 this q = 0.6
The allelic frequency p for the T allele can then be calculated using this formula p + q = 1
Where q is 0.6 thus p= 1 - 0.6 = 0.4.
This the allelic freq of T is 0.4
Answer:
What are DNA vaccines? - Biologybiology.kenyon.edu
Explanation:
DNA vaccines are third generation vaccines. They contain DNA that codes for specific proteins (antigens) from a pathogen. The DNA is injected into the body and taken up by cells, whose normal metabolic processes synthesize proteins based on the genetic code in the plasma that they have taken up.
Answer:
Growing new trees to replace old trees
Explanation:
Growing new trees in place of old ones sustains the environment, since trees help circulate oxygen and provide homes and nutrients for animals and other plants.
Any form of mining is bad for the environment and unsustainable in the long run, garbage is the same way, and putting it on land is only slightly better, and switching to other resources doesn't do anything but burn out more resources and does nothing to sustain anything.
Hope this helps :)
