The so-called LH surge causes the release of the mature egg from the ovary-this is ovulation. Ovulation normally occurs 24 to 36 hours after the LH surge, which is why the LH surge is a good predictor for peak fertility. The egg can only be fertilised for up to 24 hours after ovulation.If it isnât fertilised the lining of the womb is shed (the egg is lost with it) and your period begins. This marks the start of the next menstrual cycle. While an egg only survives for up to 24 hours, sperm can remain active for up to five days.he so-called LH surge causes the release of the mature egg from the ovary-this is ovulation.

DNA is the molecular code that codes for all proteins which make up life, a gene is a piece of dna that codes for one protein.

One set is inherited from the father, and one set is inherited from the mother. A DNA is a sort of a bio molecule. The entire DNA in cells can be found in individual pieces that are called chromosomes. The main difference between DNA and chromosome is regarding the role of genes.DNA stands for deoxyribonucleic acid. The DNA is basically made up of cytosine, adenine, thymine and guanine.ll of these are basic building blocks of the body. DNA is the smallest part that, together with proteins, forms a chromosome. A chromosome is therefore, nothing but a chain of DNA that has been made compact enough to fit into a cell. Summary: 1. Both chromosomes and DNA make up an important part of a personâs genes. 2.
