Chromosomes assist in the process of cell division by distributing DNA. They act as a container to hold in the DNA molecules

Every living creature relies on cell division for its existence. Cell division is essential for the organism to grow and function. In order for cell division to occur, new cells need to receive the genetic information contained in the DNA. Because DNA molecules are too large to fit inside the cells, chromosomes ensure that the DNA makes it to the cells by holding them in and keeping them attached to proteins known as histones.

If the structure of a chromosome changes before being transferred to the new cell, malformations can occur. Similarly, if the number of chromosomes is incorrect, it can create a genetic defect. Illnesses, such as cancer, may occur as a result of a defective chromosome. Down syndrome is an example of a condition that is caused by a chromosomal error. A person with Down syndrome has an extra copy of their 21st chromosome.

Genetic information is contained in the DNA and carried by the chromosomes. This material influences the traits and characteristics inherited by the offspring. Traits, such as flower color and seed shape, in plants are determined by this genetic information. In humans, the offspring inherits two sets of chromosomes, one from each parent. The combination of these sets determines characteristics like hair color, eye color, height, and gender. Information about gender is set by the X and Y chromosomes. Males have an X chromosome and a Y chromosome, while females have a pair of Y chromosomes.

Chromosomes are responsible for containing the instructions that make an offspring unique while still carrying traits from a parent. It is important, because the structure of the chromosome helps ensure that the DNA is tightly wrapped around the protein. If it wasn't for the help of the chromosome the DNA molecule would be extra large for the cells.

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?
