This mutation type is a substitution mutation. Substitution mutations may be silent or may have adverse effects (missense mutation).
Adverse effects come about because the change in codons in mRNA transcribed from the DNA strand. A point substitution can change the amino acid being coded for in the particular polypeptide change. If that animo acid is a structural residue of the protein, the structure of the protein will be altered, which may or may not lead to a change in protein function. If that particular amino acid is a catalytic residue of the protein, it may alter the 3D conformation and charge of the active site (if protein is an enzyme) or the binding site of protein. Function of protein formed from mutated DNA will be lost or altered.
Hope this helps! :)
Answer:
The correct answer is - true.
Explanation:
The scientific journal is are the journals that publish the recent scientific findings or scientific experiments that produce new and appropriate results regarding particular experiment or research/
To confirm an experiment, published finding must be tested repeatedly by different scientists and researchers and see if the results are same in particular conditions.
Thus, the correct answer is - true.
Position of the gene’s promoter on the chromosome
