Answer:
The correct option is D. <u>Helicase</u> is the enzyme that unwinds that double stranded DNA at the beginning of DNA replication.
Explanation:
DNA replication can be described as a process by which the strand of DNA gets duplicated into two new daughter strands.
Helicases can be described as the enzymes whose main function is to unwind the double helix structure of the DNA. The helicases break the hydrogen bonds present between the two strands of DNA. The helicases are the first machinery for DNA replication as they form the replication fork and begin unwinding of the DNA from the origin of replication
The marine biome is the largest on Earth
The answer is autosomes.
<span>In
a human diploid somatic cell (2n), there are 22 chromosomes
present in two copies and 1 pair of sex chromosomes. This means
there are 23 pairs of chromosomes - 22 pairs of autosomes and 1
pair of sex chromosomes. There are in total 46 chromosomes (23 pairs
in 2 copies: 23 × 2 = 46).</span>
Adaptive genetic traits that give an advantage to an individual and can be passed on to offspring.
<h3>What is adaptive trait ?</h3>
Adaptation is an evolutionary process which fits organisms to their changing environment and increases their evolutionary fitness.
It can be phenotypic or adaptive trait in each individual organism evolved by natural selection.
Structural adaptations are the changes in external and internal structures of animals which help them to adapt their environment.
Behavioral adaptation include Action and behavior for survival against the changing environment.
Physiological adaptations help the organisms to live and survive in their environment with unique niches like hibernation and aestivation.
