DNA and RNA
-
In a DNA molecule, two strands of nucleotides bond according to the rules of complementarity.
-
-
DNA is found in chromosomes. In eukaryotic cells, chromosomes always remain in the nucleus, but proteins are made at ribosomes in the cytoplasm
DNA replication is the semi-conservative process by which a cell’s entire DNA is copied, or replicated.
During DNA replication, the two new strands of DNA are “built” in opposite directions, starting at replication forks.
RNA is the middle player in the central dogma of molecular biology.
RNA carries the genetic instructions from the nucleus to the cytoplasm.
-
DNA – Deoxyribonucleic Acid – the molecule which contains genetic information (genes). In many cells DNA is located in the nucleus.
RNA – Ribonucleic Acid – the molecule that helps read the genetic information stored in DNA and convert it into proteins.
DNA and RNA are composed of smaller individual units called nucleotides. Each nucleotide is composed of a sugar, a phosphate and a nitrogenous base.
DNA Is split up into different locations which is genes. and genes can be turned on and off and different sets of genes are turned on in different types of cells.
there are four varieties of DNA nucleotides, depending on what nitrogenous base is attached to the deoxyribose sugar.
-
mutations- change in the sequence of nucleotide in DNA that may or may not change the phenotype of an organism.
