A) Use these five words in one sentence to explain how proteins are made (This is also known as the "central dogma" of molecular genetics:)
DNA, mRNA, codon, translation, transcription.
B) When a gene from a bacterium is inserted into a corn plant, we would call this corn plant a _______ organism. Why is this done with some crops?
Answer [A]: DNA is transcribed into mRNA via the transcription process and then mRNA triplet codons undergo the process called translation to produce amino acid sequence of a protein.
Explanation: DNA (Deoxyribonucleic Acid) undergoes the process called transcription to produce mRNA sequence.
- This process takes place in the nucleus as genetic material is present in the nucleus.
- Then this mRNA sequence moves to cytoplasm where it undergoes the process called translation.
- During translation this mRNA sequence gets sorted into triplet codons.
- This triplet codon codes for particular amino acids. Hence a chain of amino acid is formed which in turn produces functional protein.
Answer [B]: transgenic organism.
- Genetic modification in plants provide characteristics like
Explanation: Transgenic organisms are genetically modified organism in which at least one gene is inserted into its DNA from other species or organisms.
- Transgenic Corn is also called as Bt-Corn as a gene is inserted into this plant from the bacterium species: Bacillus thuringiensis.
- This makes the corn plant resistance to insects.
