The sequence of amino acids was controlled by the information in the RNA molecules.
The sequence of amino acids in a protein and its function is defined by the genetic code. Sequence in which amino acids are arranged in a protein is called primary structure.
The linear sequence of amino acids constitutes a protein's primary structure. The sequence that is written from the amino-terminal end to the carboxyl-terminal end. Sequence of bases in the DNA of the gene determines the sequence of amino acids in the polypeptide. In general , Proteins have either single polypeptides or more than one polypeptides linked together.

A scientist finds what she thinks is a new species of rodent on a small pacific island. However, some similar-looking rodents inhabit some nearby islands. She mates the new rodent with the nearby rodents and gets viable but infertile offspring. Why?.
The new rodents probably derive from fairly recent ancestors that experienced dispersive allopatric speciation.
Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics. Rodents evolved from a common ancestor with lagomorphs, forming the clade Glires.
It is also known that humans and rodents are formed separately from a common ancestor about 80 million years ago, while rats and mice diverged between 12 and 24 million years ago. In recent studies all three species share 280 large chunks of chromosomes these are virtually identical, suggesting that they are imperative.

How doe the meaning of ""mutation"" differ in cience compared to in everyday language?
Alleles, or slightly different forms of the same gene, are produced as a result of mutation. Every individual is unique because of these minute variations in DNA sequence.
Does it make sense to consider the benefits and drawbacks of mutation?Depending on the context or location, mutational impacts may be advantageous, detrimental, or neutral. Most neutral mutations are harmful. Generally speaking, the effect of a mutation and its likelihood of being detrimental increase with the number of nucleotide sequences that are impacted by the mutation.
What results in mutation?Mutations can be the result of viral infection, exposure to mutagens, or mistakes in DNA replication in cell division. Somatic mutations, which occur in body cells rather than in eggs or sperm, cannot be passed on to offspring but germline mutations can.

Prezygotic barriers are reproductive barriers that prevent mating between species or hinder fertilization if mating occurs. Examples of prezygotic isolating mechanisms include geographical isolation, behavioral isolation, temporal isolation, and mechanical isolation. Postzygotic barriers are reproductive barriers that prevent hybrid offspring from surviving and reproducing. Examples of postzygotic barriers include hybrid inviability, hybrid sterility, and hybrid breakdown. Postzygotic effects are the evolutionary effects that result from the mating of two individuals of different species, resulting in hybrid offspring.

why are there 46 chromosomes in body cells but 23 chromosomes in sex cells
This is due to the fact that each of our chromosomes is paired up, with one chromosome from each pair coming from each biological parent.
Why do sexual cells have fewer chromosomes than non-sex cells?Reproductive cells like sperm and eggs are referred to as gametes or sex cells. Chromosome count must be cut in half as gametes are created. Why? Gametes need to have half the number of chromosomes found in healthy body cells because the zygote has to have genetic material from both the mother and the father.
Meiosis, a form of cell division, makes sure that every generation of people has the same number of chromosomes. To create sperm and egg cells, a two-step process that cuts the number of chromosomes in half (from 46 to 23) is used.
This is due to the fact that each of our chromosomes is in a matched pair, with one chromosome from each biological parent inheriting each pair. As there are 23 pairs of these chromosomes in every human cell, our diploid number is 46 and our "haploid" number is 23. 22 of the 23 pairs have been identified as autosomes.
