Chromosomes are formed of strands of DNA molecules which contain information for the development of different characteristics and performance of various metabolic activities of the cells. The only thing you can say is that organs and tissues are made of many cells, so they tend to be bigger than cells. In spite of this, however, there is no definite evidence of non- DNA linkers between DNA sub-units. This test looks for changes, or abnormalities, in the chromosomes that make up your body's DNA, or genetic road map. Chromosome 2.

A chromosome is a long strand of DNA which is coiled up with various proteins. Advertisement Advertisement New questions in Biology. Sometimes a mutation doesnt change how your body works,but sometimes that mutation means that you cant function normally. They multiply during cellular division (mitosis or meiosis). A proteins job is to tell your body what types of physical characteristics you should have, like your hair and eye color. When your cells divide, they hand-write your bodys instruction manual by copying the original document word for word. From largest to smallest, the order of the set is 0.7, 0.33, 0.045.

This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. This number, along with the visual appearance of the chromosome, is known as the karyotype,[1][2][3] and can be found by looking at the chromosomes through a microscope. In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern. Chemistry 7. What is a trophic hormone? After the gel has .

Your DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The lowest diploid chromosomal number in mammals. This number includes 22 pairs of autosomes, and one pair of sex chromosomes. DNA: DNA stands for "deoxyribose nucleic acid.". The Chromosome has a very tiny structure. Also, all its chromosomes are approximately equal in size. The sex chromosomes are called X and Y. Which part of the male reproductive system store the sperm? Chromosome: Chromosomes are the threadlike structures located inside the nucleus of animal and plant cells.
