Answer:
correct.
Explanation:
cell will proceed to S phase for the duplication of chromosomes.
Correct answer: Option D- DNA ligase
Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.
The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.
Answer:
What is population?
A group of organisms of different species interacting with each other and the environment is called populatin.
Answer:
Through natural selection, those organisms which have better adaptations to survive in an environment are able to live and pass on their alleles to their offsprings. Hence, any trait which is beneficial to an organism will be favoured by natural selection.
As tissue pockets is a trait which is required by the shrimps, hence with the passage of time shrimp population having tissue pockets will increase and will be favoured by nature.
