Answer:
As this is DNA replication, this is the unwounding process
Explanation:
In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-anealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwounding. An example is the gyrase
Answer:
A. meiosis.
Explanation:
Meiosis is one of the two major types of cell divisions in living organisms. Meiosis is the process by which four daughter cells that are genetically different from the parent cell are produced. Meiotic process is carried out solely during sexual reproduction to yield gametes or sex cells.
The gametes have their chromosomal number reduced by half during the process. However, one immense importance of meiosis is that it PROMOTES GENETIC DIVERSITY. A process called crossing over, which is the exchange of chromosomal segment between non sister chromatids, makes this possible.
Answer:
soluble molecules
Explanation:
Soluble molecules dissolve completely when mixed with water, hence forming a solution
