Study Notes

DNA Structure and Function

DNA has a twisted ladder shape, often described as a double helix.
There are four types of bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
These bases pair up in a specific way: A with T, and C with G.
Certain sections of the DNA ladder make up protein-coding genes.
Each protein-coding gene is a specific sequence of base pairs, which contains a set of instructions for making a specific protein.
Proteins are the building blocks for everything in the body.

Genetic Engineering

Genetic engineering involves altering an organism's DNA using genetic engineering techniques.
This process can involve the specific modification of DNA, including the transfer of specific DNA from one organism to another.
Genetic engineering involves four main steps: (1) Identify, (2) Isolate, (3) Insert, and (4) Grow.

Keratin 1 (KRT1) Gene

The Keratin 1 (KRT1) gene provides instructions for making a protein that is part of the keratin family.
The KRT1 gene has a hypothetical DNA sequence, which can be transcribed into messenger RNA and translated into an amino acid sequence.
The amino acid sequence code for Keratin 1 is: Met-Glu-Lys-Pro-Pro-Glu-Leu-Glu-Glu-Ala-Pro-Arg-Ala-Ser-Thr-Ala-Ser.

Genetically Modified Organisms (GMOs)

A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques.
GMOs can be created to have specific traits, such as pest resistance or virus resistance.

Examples of GMOs

Sub1 Rice is a genetically modified rice that has been engineered to resist flooding.
Bt corn is a genetically modified organism that has been engineered to express a protein toxic to certain insects.
Rainbow Papaya is a genetically modified variety of papaya that has been engineered to resist the papaya ringspot virus (PRSV).
