B is your answer to your question
Answer: A substitution mutation can be defined as a mutation in which a single nucleotide is replaced by the other. As a single nucleotide changes in this process which does not create an effect on the final protein so it is a least dangerous type of DNA mutation.
Explanation:
There are three types of substitution mutation:
1. Silent mutation: In this the replaced single base pair gets replaced by the mutated RNA sequence producing the same amino acid. If the nucleotide composition gets changed it will produce the same amino acid.
2. Missense mutation: The nucleotide composition gets changed as a result of addition of different amino acid after mutation in the protein.
3. A nonsense mutation involves the change in the stop codon. This results in non-functioning of the protein.
Answer:
The DNA is more closer to bacteria.
Explanation:
Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.
The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome. Both the organelle and bacterial DNA are double stranded and their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.
Thus, the DNA is more closer to bacteria.
Heat is produced by matter. Matter is made up of atoms and molecules and energy causes the atoms and molecules to always be in motion. ... Molecules move slower in cold things and molecules move faster in hot things. The more molecules, more heat.
