Chromosomes
|
Structures in a cell's nucleus that are composed mostly of genes. The are located on long molecules of DNA.
|
|
|
|
DNA (deoxyribonucleic acid) contains...
|
the genetic code for making up proteins in the cell.
|
|
|
|
Chromosomes are responsible...
|
for carrying genes from parent organisms to their offspring. Rod-shaped structures in the nucleus of each cell.
|
|
|
|
Reproductive Cells
|
Have half the number of chromosomes than an organisms other cells. Ex. Human sex cells have 23 chromosomes & other cells have 46.
|
|
|
|
One chromosome can contain thousands of genes on a single molecule of DNA.
|
|
|
|
|
Sides of the DNA are made of DEOXYRIBOSE - a sugar - and a phosphate.
|
|
|
|
|
DNA STRUCTURE
|
Each ring of the ladder is made up of a pair of nitrogen based.
These 4 bases: adenine(A), guanine(G), thymine(T), cytosine(C). These 4 bases pair up in a specific way: A always pairs up with T, and G always pairs up with C. |
|
|
|
DNA Controls...
|
The cell's reproduction of proteins, which help determine all the characteristics & processes of the organism.
|
|
|
|
Protein Synthesis
|
1. Protein Synthesis - information from a gene from a cells nucleus is used to produce protein in ribosomes.
2. RNA(Ribonucleic Acid) - transmits code the from DNA 3. Codon- set of 3 bases pairs on the RNA(codes for amino acid) 4. Amino Acid - building block of protein. |
