Which of the following statements is false? - DNA polymerase joins nucleotides in one direction only. - The leading strand of DN
stiv31 [10]

DNA replication proceeds in one direction around the bacterial chromosome.

Explanation:

Replication of DNA is preserved across most of life. Therefore, even bacteria DNA replication occurs bidirectionally. During replication of DNA, A primer is required in the initiation complex before DNA polymersae can begin replication. This is because this enzyme works by adding DNA nucleotides at the 3’ end of an existing strand. DNA can have several replication forks on one double strand in which replication occurs. For every fork, there is a leading strand whereby the replication process by DNA polymerase is continuous and the lagging strand whereby the replication is done in bits by the same polymerase enzymes. The lagging strand will, therefore, require many primers. This is becaue strands of DNA are antiparallel yet the DNA polymerase has to move in one direction. Since replication can only occur in the 5’⇒3’ direction, the antiparallel strand will be done in 5’⇒3’ chunks that will later be joined into one strand.

Two years of dry weather are followed by two wet years, causing the grass population to rise. How will the increase in grass aff
Ulleksa [173]

Answer is;

The animal population in the environment will increase.

This is because the grass is the main producer in a habitat. Its plentifulness directly influences that of the consumers up the food web. Increase in grass population means reduced competition for primary consumers and their population will therefore increase. This will also reduce competition for secondary consumers and tertiary consumers up the chain.
