Answer:
substitution mutation
Explanation:
The original DNA sequence is: TACTTTAATCCCAAATTTACT
The mutated DNA sequence is: TACTTTAATCCCAAGTTTACT
The mRNA transcribed from the mutated DNA sequence is: AUGAAAUUAGGGUUAAUUAGA
The amino acid sequence encoded by the mRNA is: Met-Lys-Ser-Trp-Lys-Lys-Ser
This is an example of a substitution mutation, in which a single nucleotide in the DNA sequence is changed. In this case, the original DNA sequence contains the nucleotide A at position 13, while the mutated sequence contains the nucleotide G at the same position. This change causes a different mRNA sequence to be transcribed and a different amino acid to be encoded. Substitution mutations can have a variety of effects on gene function, depending on the location and nature of the mutation. Some substitution mutations may have no effect, while others may cause the protein encoded by the gene to function improperly or not at all.

In a molecular cloning procedure, the DNA to be copied is extracted from a target organism and split into smaller DNA fragments in a test tube using enzymes.
These pieces are subsequently joined with vector DNA to produce recombinant DNA molecules. After that, a host organism is given the recombinant DNA (typically an easy-to-grow,strain of E. coli bacteria). Recombinant DNA molecules will be duplicated alongside the host DNA in the resulting population of organisms. These are transgenic or genetically modified organisms because they have foreign DNA pieces. Thus, the term "clone" is frequently used to describe both the bacterial population and the recombinant DNA molecule. In actuality, molecular cloning refers to the scientific techniques utilised to put them together.The idea arose that different DNA sequences could be inserted into a plasmid and that these foreign sequences would be carried into bacteria and digested as part of the plasmid. That is, these plasmids could serve as cloning vectors to carry genes.

What creates the boundaries for the distribution of a trait within a population?
The variation and distribution of traits in a population depend on genetic and environmental factors.
Different traits can be introduced into an organism by genetic variations that alter gene activity or protein function. If a trait is beneficial and aids an individual's survival and reproduction, the genetic variation is more likely to be passed down to the next generation.
Mutations create new alleles over time, resulting in genetic diversity. Mixing alleles from parents results in new allele combinations in their children. Bacteria and other organisms that can clone themselves can pass on alleles to each other.
Each genotype in a population has a different fitness for that specific environment. In other words, certain genotypes will be preferred, and people with those genotypes will continue to reproduce. Other genotypes will be discouraged: people with those genotypes are less likely to reproduce.

species that undergo sexual selection often have males and females that differ dramatically in phenotype, a phenomenon called sexual dimorphism. since sexual dimorphism is a result of selection for the two extremes of a phenotypic trait, what pattern of selection is this?
Option A disruptive is the correct answer. This pattern of selection is disruptive because it favours the two extremes of a phenotypic characteristic, which results in sexual dimorphism.
Sexual dimorphism is the systematic shape difference between individuals of different sexes within the same species. For instance, the male in some species, such as many animals, is bigger than the female. The female of some species, like some spiders, is larger than the male. This sexual dimorphism has been noted in early development studies, childhood, adolescence, and maturity. On average, males' total brain size is around 8%–15% greater than females' (uncorrected for body size).
As a result, we can conclude that Option A disruptive is the best choice. Sexual dimorphism results from selection toward the two extremes of a phenotypic characteristic, hence this pattern of selection is disruptive.

scientists believe that perching birds originated on the continents of australia and antarctica. how would these scientists explain the discovery of ancient perching bird fossils in africa?
The concept that dinosaurs were the direct ancestors of birds was backed by new research on ancient specimens as well as by field finds of dinosaur and early bird species.
Numerous traits and behaviours that distinguish modern birds were also present in dinosaur forebears. Theropods were a class of meat-eating dinosaurs from which birds descended. Although birds originated from little theropods rather than gigantic ones like Tyrannosaurus rex, they nonetheless belong to the same group as the dinosaur. The earliest fossilised bird remains date back 150 million years. Since they have a foot structure that enables them to grip branches, many bird species, including the majority of songbirds, are also known as "perching birds."

Proteins are constructed from a set of 20 amino acids in a variety of configurations. For every four nucleotides and 20 amino acids, there are 64 potential codon configurations, provided that at least three bases are present.
Given the genetic code's degeneracy, numerous codons encoding the same amino acid are not required because the genetic code carries more information. As there are three base pairs each codon and three DNA base pairs every base pair, there are nine potential substitutions for each DNA base pair.
