<span>DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a template for replication. Primers bind to the DNA and DNA polymerases add new nucleotide sequences in the 5′ to 3′ direction. This addition is continuous in the leading strand and fragmented in the lagging strand. Once elongation of the DNA strands is complete, the strands are checked for errors, repairs are made and telomere sequences are added to the ends of the DNA.</span>
Answer:
Biologists measure the number of trophic levels in an ecosystem so as to check its stability and health.
Explanation:
Trophic levels are the feeding position in a food chain such as primary producers, consumers, etc. They are positions that an organisms occupies in a food chain (series of steps in which organisms transfer energy by eating or being eaten);- what it eats and what eats it.
Theoretically there is no any limit to the number of trophic levels in a food chain or number of organisms that live on each level.

Answer:
AAATT - TTTAA
CGCAT - GCGTA
GGGAC - CCCTG
ACGGT - TGCCA
Explanation:
In DNA, A and T, also known as adenine and thymine pair together and G and C, also known as guanine and cytosine pair together due to the hydrogen bonds formed between the two bases.
