d) Replication; creating two complimentary strands of DNA.
<h3>EXPLANATION:</h3>
DNA replication is a process that occurs during cellular division where two identical molecules of DNA are created from a single molecule of DNA. As a semiconservative process, a single molecule containing two strands of DNA in double helix formation is separated, where each strand serves as a template for the new DNA molecules.
Because the <u>double helix is anti-parallel and DNA polymerase</u> only synthesizes new DNA from 5′-3′, the template strand reading 3′-5′ results in a continuous, leading strand, while the template strand reading 5′-3′ results in a discontinuous, lagging strand.
Being a highly regulated process, multiple proteins are required both during and following replication to quickly correct mistakes and damages.
No idea but hopefully this cheers you up!
Answer:
Biosphere comprises all the life that exists on earth including animals, plants, water bodies, microorganisms, algae, fungi etc.
If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.
There would be no negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.
Hope it help!
Answer:
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

Explanation:
All linear chromosomes the newly synthesized strands of DNA are shorter at the 5' prime and then that same region of the parental strands. There is a 3’ overhang at one end of the daughter strand strand;mboth resulting daughter DNA strands 3' overhangs. Without any other cellular process these overhangs are typically digested by nucleases. However this would lead to the shortening of daughters DNAs with each replication of parental DNA.
To combat this chromosomes in eukaryotes contain regions called telomeres. These have repetitive non-coding sequences which function to protect important genes from deletion during cell division and DNA shortening during the process of DNA replication.
