Your three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are ___________, which give the instructions for cell processes. These instructions include the differentiation of your blood cells. A) centromeres B) chromosomes C) karyotypes D) mitochondria

Answers

Three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are chromosomes which give the instructions for cell processes.

What is chromosomes?

The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.

There are 46 chromosomes in all, including 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY). Children receive half of their chromosomes from their mother and half from their father because each pair comprises two chromosomes, one from each parent.

The dissolution of the nucleus during cell division allows for the visualization of chromosomes under a microscope. All animals and plants, including humans, have linear chromosomes.

Therefore, Three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are chromosomes which give the instructions for cell processes.
