Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
Answer:
NADPH
Explanation:
The correct option is, option 4 (<u>NADPH</u>).
Petroleum is the primary fuel used for transportation in the US because it has a high energy value per unit volume and it has a quick start and stop times for providing energy. Additionally, petroleum is extremely easy to extract, it is a high density fuel, can also be transported over long distances and provides fuel that works with our infrastructure.
It is to help transport macromolecules back and forth between the nucleus and the cytoplasm. the nuclear pore complex also serves as a barrier between the cytoplasm and nucleus to prevent harm to genetic material housed in the nucleus :)
