What are the two main parts of a chromosome?

What are the two main parts of a chromosome?

DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.

Who discovered the chromosome?

Walther Flemming

Who is the father of chromosome?

Hermann Henking

Who invented the gene?

Danish botanist Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity. He also made the distinction between the outward appearance of an individual (phenotype) and its genetic traits (genotype).

Is Gene a part of DNA?

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

Are we our genes?

Human cells have about 25,000 genes. The genes of different members of the same species are almost identical. The DNA in your genes, for instance, is about 99.9% the same as the DNA in my genes and in the DNA of every other human being.

How do our genes affect us?

Genes can carry instructions that can make it more likely for you to develop certain illnesses or conditions. For example, Jennifer and Karen both have genes associated with obesity. Their genes could tell their body to: increase the size of their fat cells or dictate how they use fat in their body.

How do we get our genes?

You got all your genes from your parents. For each pair of their chromosomes, you get one chromosome from your mother and one from your father. When the egg and sperm cells come together, they create the full set of 46 chromosomes or 23 pairs.

Do your genes control your future?

Everything about yourself and your life could be under the influence of your genes, new research says. Genes play a greater role in traits as self-control, decision making or sociability than previously thought.
