Answer:
The sequence from least damaging to most damaging is silent, missense, frameshift, and nonsense mutation.
Explanation:
A silent mutation refers to a modification in the sequence of nucleotide bases that constitutes DNA, however, it does not result in a substantial change in the amino acid or in the function of the entire protein. In missense mutation, one DNA nucleotide gets switched out with another one in a manner, which modifies the specified amino acid.
When a missense mutation takes place in the molecule of DNA, it changes one of the sequences of RNA codon produced at the time of transcription. A frameshift mutation refers to a specific kind of mutation, which comprise either deletion or insertion of the additional bases of DNA. Following the mutation, the entire sequence of DNA will be read incorrectly.
A nonsense mutation refers to a genetic mutation in the sequence of DNA, which leads to the formation of the shorter or unfinished protein product. This mutation takes place when an undeveloped nonsense or stop codon gets presented in the sequence of DNA.
Thus, the silent mutation is the least damaging as it does not exhibit any influence on the function or composition of the protein. While nonsense mutation shows the most damaging effect as it results in an abrupt termination peptide chain.
Answer:
Homologous features
Explanation:
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Answer:
is the genetic material that makes up living things, and folic acid plays an important role in the formation of DNA. Jon wants to study the effect of folic acid on DNA formation in microbes. Which statement accurately describe the variables in this study?
Folic acid is the variable as it determines how DNA is formed, DNA contains the genetic materials that is passed across to offspring
Explanation:
Answer:
If you were to ask me I would say that your answer is C
Explanation:
Answer:
In the course of evolution mammals are the animals which are evolved recently as compared to other groups such as fish, amphibians, or reptiles.
In addition, fur or hairs on body, mammary glands, middle ear bone, warm-blood, et cetera are the characteristics of mammals.
These characteristics were evolved during the course of evolution; they were not present in ancestral organisms.
However, tail, gill pouches, et cetera are characteristics of our ancestral groups. Thus, characters can be sometimes observed in mammals.
But mammals characteristics can not be observed in organisms which were evolved before mammals such as fishes, amphibians, reptiles, et cetera.
