Which process describes the function of the category of enzymes known as DNA polymerases?
A. Add new nucleotides to a strand and repair any errors
B. Unwind the double helix of DNA
C. Separate the complementary strands of DNA
D. Bond together groups of nucleotides on the lagging strand

The process that describes the function of DNA polymerase is add new nucleotides to a strand and repair any errors (option A).

Explanation:

In the context of DNA replication, a complementary strand must be formed using an existing strand as a mold. This replication process is facilitated by the enzyme DNA polymerase, which is responsible for binding complementary nucleotides to the new strand, following the sequence of the original strand.

Additionally, this polymerase can correct or repair any error in the base sequence —together with its exonuclease activity— guaranteeing the integrity of the genetic information contained in the DNA and avoiding possible mutations.

The other options are not correct because:

    B. Unwinding the DNA double helix or separating the complementary DNA strands is done by the enzymes topoisomerases and heliases.

    D. Bonding together groups of nucleotides on the lagging strand is done by ligase enzymes.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
