Answer:
Explanation:
The correct answer is (B) Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. The replication fork is established by the enzyme DNA helicase, which separates the two complementary strands of a DNA molecule
Answer:
By using sequence information from covalently attached nucleotides.
Explanation:
TRNA presents an anticodon sequence to required sites as a physical bridge with elongation factors (proteins) to form a connection between mRNA and ribosome and encode amino acids to ultimately form specific protein structure. tRNA carries out this activity by using sequence information from covalently attached nucleotides.
3. naturally occurring
4. fossilized plants or air bubbles ( probably the plants tho)
5. increased
6. the green house effect occurs naturally, it is being polluted both naturally and unnaturally, the unnatural pollution is contaminating our 'greenhouse" and that is horrible.<span />
