WHAT IS A CHROMOSOME?

Chromosomes are found in the nucleus of every cell of our body and are made up of DNA, tightly coiled around proteins. We have 23 pairs of chromosomes altogether, and they can only be easily observed during cell division.

RELATIONSHIP BETWEEN DNA, GENE AND CHROMOSOME

WHAT ARE TRAITS?

-are inherited or genetically determined characteristics

WHAT IS DNA?

DNA is DeoxyriboNucleic Acid which contains genetic information or genetic code of an organism

THE DOUBLE HELIX STRUCTURE OF DNA

The Double Helix Structure was worked out by James Watson and Francis Crick in 1953

NUCLEOTIDES ARE THE BUILDING BLOCKS OF DNA

COMPLEMENTARY BASE PAIRING IN DNA

A (Adenosine) always pairs with T (Thymine) and T (Thymine) always pairs A (Adenosine) in a DNA molecule
G (Guanine) pairs with C (Cytosine) and C (Cytosine) pairs with G (Guanine). This complementary base parining in DNA forms the genetic code of an organism.

Intro to Genetics worksheetLiveworksheets transforms your traditional printable worksheets into self-correcting interactive exercises that the students can do online and send to the teacher.

WHAT IS CELL DIVISION?

When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process "cell division" and "cell reproduction," because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms

MITOSIS

-is a process by which a cell divides into two identical daughter cells

-occurs in the body cells(somatic cells) for growth and repair of body tissues

MEIOSIS

-is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent).
