What is the role of the dna ligase in dna replication apex?

DNA replication is a process where strands of DNA are copied and two new daughter DNA molecules are formed. In this process, a number of enzymes and factors are used and one of them is DNA ligase. When the nucleotides are added on the template strand, there is a nick left behind between some nucleotides. These are the Okazaki fragments. To seal this nick or gap, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of Okazaki fragments. This is how it looks like-

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
