Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.

The lactic acid fermentation is a type of aerobic respiration. The lactic acid formation is due to excessive exercise by individuals and oxygen which is essential for living, is less in the muscle which causes the feeling of burning in the muscles.
