Answer:
<h2>
DNA Helicases
, Topoisomerases
, Single-Stranded Binding Protein (SSBP), DNA primase
, DNA polymerases and DNA Ligase
.</h2>
Explanation:
DNA replication occurs continuosly in leading strand and discontinuosly in lagging strand and this strand is known as okazaki fragment.
List of six different enzyme
i) DNA Helicases: it unwind the strands of Double stranded DNA;
ii) Topoisomerase: which removes coils in the DNA;
iii) Single-Stranded Binding Protein (SSBP): prevents rebinding of DNA strands until replication.
iv) DNA primase: which synthesizes short RNA sequences called primers, that are required for the initiation of replication.
v) DNA polymerase: which actually replicate DNA and also have proof reading activity.
vi) DNA Ligase: which joins the okazaki fragments after the removal of primers.
Answer:
Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.
Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.
Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.

Answer with Explanation:
When it comes to the study of the outer space, <u>astronauts play a vital role in giving people significant information regarding their exploration.</u> Most of the missions last for 6 months in space and this is followed by another mission lasting at the same time or so.
When astronauts travel, <em>they need to bring exact amounts of products that they will be using during their expedition.</em> These products are particularly related to personal items that they need in order to survive. However, <u>these items have to be calculated in terms of their weight, since the space craft can only accommodate a certain amount of mass. </u>
The collective term for the personal items is "Personal Preference Kit" or the "PPK." It is said that an astronaut can only carry up to 20 personal items and the total weight should only be<em> 1.5 pounds. </em>
Thus, this explains the answer.
