Hi, the given question is incomplete, it is missing a diagram, the diagram is given in the attachment below,
Answer:
The correct answer is adaptive evolution.
Explanation:
Based on the given information, it is clear that it best illustrates the phenomenon of adaptive evolution. It is known that different species of finches exhibit an ancestor, which is common, however, all the species have shown adaptation based on the kind of food they are getting within their surroundings.
The evolutionary modifications that arise by getting adaptive to the specific environment are termed as adaptive evolution. These changes arise due to the phenomenon of natural selection, which further enhances the tendency of reproducing or survivorship after going through some of the challenges presented by the surroundings.
Answer:
a. transcription/RNA processing
: pre-mRNA, snRNA
b. translation
: mRNA, rRNA,
c. not used in protein synthesis: RNA primers
Explanation:
pre-mRNA, mRNA, rRNA, RNA primers, snRNA
a. transcription/RNA processing
: pre-mRNA, snRNA
b. translation
: mRNA, rRNA,
c. not used in protein synthesis: RNA primers
The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
The answer is length.
A gel electrophoresis is used for separation of DNA or its fragments on the basis of differences in their length. An electric current is running through the gel with positive pole on the bottom. Because of the difference in the lengths of DNA fragments, some <span>of them </span>will travel more quickly than other. It is expected to see smaller DNA fragments at the bottom of the gel and larger DNA fragments near to the top of the gel.
