DNA: The Cold Facts

DNA stands for deoxyribonucleic acid. It is the main constituent of chromosomes and the carrier of genetic information.

DNA is found in the nucleus.

It is made of deoxyribose sugars.

The structure of DNA is a shape called a double helix.

DNA contains the instructions needed in order for an organism to develop, survive and reproduce. DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies, so they can carry out these tasks.

Heredity the passing on of physical or mental characteristics genetically from one generation to another.

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules

-Protein Production...
When protein synthesis is taking place, enzymes link tRNA molecules to amino acids in a highly specific manner.\

RNA stands for ribonucleic acid.

The types of RNA are...
-Messenger RNA, which Encodes amino acid sequence of a polypeptide. tRNA -
-Transfer RNA, which brings amino acids to ribosomes during translation. rRNA -
-Ribosomal RNA with ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA

RNA is essential for the information in DNA to remain stable.
