This is for the biotechnology Ch 4 review for the test at Diamond Oaks
Central Dogma of Biology
explains how genetic info is converted into structures an functions.
small section of DNA 30,000 in humans
messenger RNA, which copies the gene from DNA
_______ proteins are synthesized in a typical cell
entire sum of DNA in a cell
4 nitrogen bases are:
Adenine, Thymine, Cytosine, Guanine.
DNA is made up of:
nucleotides which consits of a phosphate, sugar, and a nitrogen base
Nucleotides are held together by:
Phosphodiester bonds that are between the sugar and phosphates.
What bonds hold the sides of the DNA molecule together
Hydrogen between nitrogen bases.
DNA oriented in opposite directions
The nitrogen bases are stacked ______nm apart with _____ pairs per complete turn of the helix
.34nm 10 pairs.
making two daughter strands from a single parent strand
source of nutrients.
process of cell being broken down
-DNA is in one long circular DNAmolecule (Chromosome.)
-Plamid-small ring of DNA floating in cytoplasm.
when a plassmid which has a "gene of interest" is put into another cell.
Eukaryotic DNA is
packaged into chromosomes.
does not have cellular structures
Virus that attacks bacteria
Gene therapy and viruses-
use of viruses as vectors to go and infiltrate bad cells and give them good genes to correct a problem.
Steps to genetic engineering
1. Identification of the molecule of interest.
2. Isolation of gene.
3. Transforming or manipulation of DNA.
4. Harvesting the new product.
taking a gene of interest and putting it into a cell to have it express that trait or protein.
Site specific mutagenesis-
The process of inducing changes in certain sections of a particular DNA code to enhance or improve the proteins functions.
