Answer: The corresponding mRNA sequence to the DNA strand will be
ATTGCGAATTC
Explanation:
Because nitrogenous bases specifically pair in the following order:
- Adenine pairs with Thymine
- Cytosine pairs with Guanine
mRNA also known as messenger RNA, which is complimentary to one strand of DNA will have its sequence as the "pairing base partner". Thus, the mRNA sequence is ATTGCGAATTC.
C. Reduced sediment flow.
Given what we know, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
<h3>What are cyanobacteria?</h3>
These are tiny bacterial organisms. They were amongst the first organisms to use photosynthesis to sustain life. The sudden boom of cyanobacteria accounts for the rapid increase in oxygen given that they will use carbon dioxide to produce sugar through photosynthesis, expelling oxygen in the process.
Therefore, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
