Describe the ways mutations can affect DNA and chromosomes.​
lozanna [386]
Mutations present permanent and heritable changes in the genome. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Deletion presents a loss of nucleotides which changes DNA sequence. When new nucleotides are embedded in the DNA chain, it is known as insertion. Substitution implies the process where new nucleotides are inserted while the ones that were present in that specific spot in a DNA molecule are deleted.
Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations - deletion, duplication, inversion, and translocation. In deletion, a whole or one part of a chromosome is lost. Duplication presents an extra copy of a whole or one part of a chromosome. In an inversion, parts of a chromosome change order, while in translocation a part of one chromosome detaches and then connects to another.

How is the information stored within the base sequence of DNA used to determine a cell’s properties?
vovikov84 [41]

Answer:

The genetic material of most of the organism is Dexoxy-ribonucleic acid OR DNA which are formed of the monomer unit called nucleotide. Each nucleotide is composed of a 5-C deoxyribose sugar, a phosphate group and 4 types of nitrogenous bases mainly adenine, cytosine, guanine and thymine.

It is the sequence of these nitrogenous bases which determine the fate of a cell as these nitrogenous bases are read by the ribosome in the form of triplets called codons where each codon codes for specific amino acids. These amino acids bind to each other via peptide bonds to form proteins.

Thus, these nitrogenous bases control the important property of the cell.

Over successive generations, moths develop spots that resemble eyes on their wings that scare off predators. this characteristic
Sati [7]
In this example of evolutionary development, we can see a selective advantage.
Developing of new characteristics, in this case, the spots on moth's wings is a part of the process of adaptation of organisms to their environment.
The new characteristics are acquired through mutations and natural selection filters the ones that are the most beneficial for the holder.
For example, a  mutation which results in moths having shorter wings is disadvantageous, because it makes the individual who possesses it less likely to survive and reproduce.
On the other hand, developing of spots that resemble eyes can be advantageous, since it enables the holder of the trait to be more successful and more likely to leave offspring.
