Answer: A mutation Changes by its mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.
Explanation:
A mutation changes the instructions of a gene, which can also change the protein. Sometimes this change makes it so the protein can't do its job as well. And this is what happens with sickle cell anemia. A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.
Answer:
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
Explanation:
Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.
According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.
In frameshift mutation, the insertion or deletion causes the
normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.
Answer: Complete dominance
Explanation: complete dominance occur when a dominant allele in heterozygous form completely mask the effect of the recessive allele.
For example a situation where Tt having two allele and allele T for tallness is dominant over t for shortness making the plant phenotype a Tall plant. This is called complete dominance.
A condition when the heterozygous allele do not completely expressed itself over the recessive allele is called Incomplete dominance.
For the plant to have a pigmented color in an heterozygous form the allen M for pigment is completely dominant over allele m for albino.
There isn't a single molecule which is metabolized to produce energy, since any organic compounds such as sugars, fats, or proteins may be used. However, the most common one is glucose sugar.
Answer: Microorganism activity affects soil acidity and the amount of organic matter in soil. It also affects the nutrient and mineral levels in soil as well as soil structure.
