Ans.
Protein synthesis involves formation of proteins, during which information present in DNA is used to make polypeptide chains. Hence, amino acid sequence of a polypeptide chain is determined by the sequence that may differ in different species having proteins with same amino acid sequence.
Thus, the molecules that are used to compare different species with proteins having exact same amino acid sequences are DNA molecules.
Protein synthesis includes two steps, transcription and translation. During transcription, DNA gets converted into RNA by RNA polymerase enzyme, while during translation, RNA provides information to make proteins.
In RNA information is present as triplets of nucleotides, known as codon. Each code codes for a specific amino acid. There are a total of 64 codons, while number of protein-forming amino acids is 20. Hence, one amino acid can be coded by more than one codon and this property of codons is known as degeneracy of codons.
Thus, two species may have the same protein even if their DNA molecules are different because of degeneracy of codons.
Answer:
it leads to the formation of volcanic islands
Nervous system is the body system that is involved in coordinating and controlling body movements
I think false because no one knows what will happen in the future and anything is possible, although the population does increase it can still decrease by high amounts aswell, anything bad could happen any time. People may not even have money to survive but it really depends on what happens and what could happen in the future, no one really knows what will happen so this statement would be false.
Anyway have a nice day :)
We can infer of the two paragraphs that Geological movements are often hazardous when they happen quickly, and that the movement of plate boundaries does not always cause disaster.
The excerpt is telling us that "the <span>earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem", which is supporting the conclusion: "geological movements are often hazardous when they happen quickly."
But is also telling us that "</span>The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.", which is supporting the conclusion: the movement of plate boundaries does not always cause disaster."
