structure of these cells is a flying disk shaped like a donut‚ this is so maximum haemoglobin can be carried allowing maximum amount of oxygen to be transported. Sperm cells A sperm cell is the male reproductive cell that carries the male portion of chromosomes and deoxyribonucleic acid (DNA) information to be fused with the female egg or ovum. The sperm cell carries various amount of heredity information inside the cell nucleus. There are various ways in which sperm can be transmitted to the egg for fertilization

These diseases or disorders can vary in effects and consequences towards the human bodies and may also greatly differ from one organism to another‚ however they can equally have identical results. They tend to affect the genes‚ chromosomes‚ cells and a few other parts of the body by altering‚ deleting‚ substituting‚ etc. the components of the previously mentioned areas. Some of these diseases in Nova Scotia are isolated and known as Usher ’s Syndrome‚ Friedreich ’s ataxia‚ Niemann

Biology 1. If an interphase cell is treated with cyanide (a metabolic poison)‚ the cell does not divide by mitosis. However‚ if cyanide is added right after mitosis has started‚ the same cell completes mitosis. Which of the following explains this observation? A. Metabolic activity ceases during mitosis B. Cell division does not require metabolic activity C. Energy required for mitosis is produced and stored in the cell during interphase D. Mitotic cells make factors that make them resistant to

Genetic Disorder Achondroplasia Cause of Disorder Achondroplasia is a single gene disorder that causes birth defects and results in short-limbed dwarfism. It is caused by mutations to the FGFR3 gene on chromosome 4. This gene prevents the growth of cartilage at the growth plate. FGFR3 encodes a protein called Fibroblast Growth Factor Receptor 3. This protein is the site of action of a major growth factor responsible for lengthening bones. When this growth factor cannot act properly due to the

The same process was followed in India‚ and Tamil Nadu was discovered to carry the gene of the past. The white chromosome in male is the evidence of the past because it is the only one that does not change. After India‚ the species continued their route towards

Dizygotic /dīzīˈɡädik/; twins derived from two separate fertilized eggs‚ making every chromosome different within the genetic makeup. From the second my life was formed‚ her life was formed - I was “Baby A”‚ she was “Baby B”. They gave me the pink stuff and her the blue stuff. Difference was a quality that was born into our DNA; a quality that has played into my life of 17 years‚ one that makes me who I am today. But whether we were two separate zygotes or “non-identical”‚ being a twin is an aspect

of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution. Prokaryotes also differ from eukaryotes in the structure‚ packing‚ density‚ and arrangement of their genes on the chromosome. Prokaryotes have incredibly compact genomes compared to eukaryotes‚ mostly because prokaryote genes lack introns and large non-coding regions between each gene. Whereas nearly 95% of the human genome does not code for proteins or RNA or includes

The second factor is genetics‚ there is actually a gene for violence‚ MAOA. This gene is only on the X chromosome so it is passed from mothers. This is why men tend to be more aggressive because in females this gene is diluted . However this factor leads to the next factor. “In order for boys to show this gene they have to go through something really traumatic
