The amino acids coded triplets in the 3' to 5' strand on the normalp53 gene of chromosome 13 are lysine, leucine, Glutamine, stop codons.
Explanation:
mRNA is formed by the transcription of DNA strand coding for a gene.
Any mutation in the DNA sequence even a difference of base pair would cause formation of different amino acids and hence altered protein.
The amino acid is formed in the step of translation where codes are read by tRNA on the mRNA strand and correct nucleotide is brought to growing polypeptide chain.
In transcription 3' to 5' strand acts a template strand. The amino acids on the p53 gene of chromosome 17 is
3'TTT AAC GTC ATC 5' Gene sequence
5' AAA UUG CAG UAG 3' mRNA
lysine, leucine, Glutamine, stop
This answer is TRUE !! Hope this helps you out a little :)
Answer:
A. would be the correct answer
Answer:
I and III only
Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.
