What is the genetic code and how are we able to read it?
- Gene Mutation
A gene mutation is a change in one or several bases. A base may be added, deleted, or substituted with another base. This is caused often through the action of damaging chemicals, radiations, or through errors inherent in DNA replication and repair reactions....
- There Are Sporadic Alterations Of The Universal Code
KEY CONCEPTS:Changes in the universal genetic code have occurred in some species. They are more common in mitochondrial genomes, where a phylogenetic tree can be constructed for the changes. In nuclear genomes, they are sporadic and usually affect only...
- Mrna Is Produced By Transcription And Is Translated
KEY TERMS:Transcription describes synthesis of RNA on a DNA template. Translation is synthesis of protein on the mRNA template. A coding region is a part of the gene that represents a protein sequence. The antisense strand (Template strand) of DNA...
- The Genetic Code Is Triplet
KEY TERMS:The genetic code is the correspondence between triplets in DNA (or RNA) and amino acids in protein. A codon is a triplet of nucleotides that represents an amino acid or a termination signal. Frameshift mutations arise by deletions or insertions...
- Homework- The Ethics Of Genetic Screening
Genetic screening already allows us to detect certain genetic disorders and the sex of an embryo or the fertilised egg in IVF treatment. As genetic testing progresses it may enable us to detect lots of characteristics. This raises the ethical question...
