Answer:
<h2> AA
</h2>
Explanation:
1. A restriction enzyme, restriction endonuclease, an enzyme that cleaves DNA into small fragments at or near specific recognition sites (different restriction enzyme has different restriction site) within molecules known as restriction sites.
2. Restriction enzymes are found in archaea and bacteria.
3 And in bacteria and archaea they provide a defence mechanism against invading viruses.
4. Each restriction enzyme cut at the specific site, because each restriction enzyme have specific recognition site.
As the bear enters hibernation, its metabolic processes such as body temperature, heart rate, and respiratory rate are reduced. But bears do not lower the body temperature as much as once thought. Their hibernation temperature is around 88 degrees and waking temperature is 100 degrees F. This relatively high sleeping temperature allows bears to become fully alert if aroused, perhaps to enable the bear to protect itself from predators and other dangers without unnecessarily taxing their energy reserves. Over the course of a hibernating season it is thought that bears use approximately 4 thousand calories a day, which results in a weight loss of about 20 percent of it body weight by spring.
the believe they move inside the membrane which is creating a gradient
1. two copies of the duplicated chromosome are attached at their centromeres before separating
2. chromosomes replicate before cell division
3. chromosome separation begins at the origin of replication on DNA
4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation
5. replicated chromosomes separate by attaching to some other structural feature of the cell
Explanation:
In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.
<u>Eukaryotes
</u>
1. Option-4 as the nuclear envelope is present in eukaryotes only.
2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.
<u>Bacteria
</u>
1. Option-3 as DNA replication process separates the strand of the DNA.
<u>Both
</u>
1. Option-5 as the chromosomes separate by other structures like microtubules
2. Option-2 as genetic material to be passed on to the generation must be replicated.
An autotroph is an organism that makes food for itself like plants
