A genetic mutation brought on by the replacement of one nucleotide with another nucleotide is called a point DNA mutation.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations. Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Point mutations involve the substitution, deletion, or insertion of a single nitrogenous nucleotide into a single base pair of DNA. The sickle cell anemia condition is a case of a point mutation. The beta-globin chain of the blood's hemoglobin pigment is affected by a single base pair mutation.

why do cells go through the cell cycle
Answer:
The most basic function of the cell cycle is to accurately copy a large amount of DNA in the chromosomes and then precisely separate the copies into two genetically identical daughter cells.
Explanation:
In Drosophila, the gene for eye color (A), wing shape (B), and body color (C) are all found on the same chromosome. The following crossover frequencies for these genes were determined by & trihybrid test-cross experiments. Determine the sequence of genes A, B, and C on a chromosome. There are two correct answers: Crossover Frequency 12% Genes A&B A&C B&C 18%
The correct sequence of the genes A, B and C found on the same chromosome can be : B A C or C A B.
Genes are the part of DNA sequences that code for a certain protein responsible for a particular trait. These genes are present upon the chromosomes. Each chromatid can contain multiple genes on it.
According to the question, the crossover frequency between genes B and C is 18 % hence they are the farthest (18% = 18 centi-Morgan). And the frequency between genes A & B and A & C is 12% and 6% respectively. Therefore the distance of B and C is the sum of the remaining two. This determines the sequence could be B A C or C A B.

Write the balanced chemical equation for cellular respiration. (Please write the equation using scientific chemical symbols and then explain the equation in writing beneath.)
The complete balanced chemical equation for cellular respiration is as follows:
C6H12O6 (s) + 6 O2(g) ------> 6 CO2(g) + 6 H2O(l) + ATP
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are through- merchandise and ATP is strength this is converted from the procedure. Cellular breathing is the procedure through which organisms use oxygen to interrupt down meals molecules to get chemical strength for mobile functions. Cellular breathing takes location withinside the cells of animals, plants, and fungi, and additionally in algae and different protists. Adenosine triphosphate (ATP) is the supply of strength to be used and garage on the mobile level.

T or F? In the muscles of the limbs, the origin is usually the immobile muscle attachment
In the muscles of the limbs, the origin is usually the immobile muscle attachment. True
A skeletal muscle connects to bone (or other muscles or tissues) at two or more points. If the location is a bone that stays motionless during an activity, the connection is referred to as an origin. If the connection is on a bone that moves during the activity, it is referred to as an insertion.
Muscle tissue is classified into three categories in the muscular system: skeletal, cardiac, and smooth. The term "structural" refers to the fact that the body has a distinct structure. Skeletal muscle is responsible for the movement of bones and other structures. To pump blood, cardiac muscle contracts.

A gene for microtubule proteins is being made in a cell. How can mRNA represent an exact copy of that gene
A gene for microtubule proteins is being made in a cell. The mRNA representing an exact copy of that gene is put together using base pairing rules.
Gene expression is the process by which genetic information carried by DNA is converted from genes via messenger RNA to proteins.
mRNA is the molecule that links genes to proteins. The mRNA is formed through the process of transcription from a gene strand. The mRNA is then translated into protein by the joint action to transfer RNA and the ribosome.
mRNA therefore, serves as a temporary copy of information found in the DNA. Thus, mRNA represents an exact copy of the gene and it is put together using base pairing rules.

What precisely is reproduction?The process of creating offspring is called reproduction. The two basic types of reproduction are sexual and asexual. An creature that reproduces sexually is extremely varied and carries the genetic material of its two grandparents. Asexual reproduction, which involves each parent reproducing themselves, results in children that are genetically identical.

Any material of small granulometry, or up to five millimeters in size, is called sand. From that measure they are called stone. Stones are the result of the breakdown of rocks, just like sand, and in the crushing process it forms crushed stone.
How is sand formed?The formation of sand begins with the action of wind, rain, sun, tree roots and microorganisms that wear down the rocks present in various regions of the continent. Over the years, pieces of the stones break loose and, little by little, turn into small grains. This process is called erosion.

How does the Devil and Tom Walker reflect Puritans
"The Devil and Tom Walker" reflects the Puritan belief in the concept of predestination, which holds that God has already predetermined the fate of every individual and that salvation can only be attained by the elect, who have been chosen by God.
Tom's encounter with the devil can be seen as a reflection of the Puritan belief in the eternal struggle between good and evil, and the constant temptation of sin.
What does "The Devil and Tom Walker" show?"The Devil and Tom Walker" is a short story by Washington Irving that was published in 1824. The story also reflects the Puritan belief in the importance of hard work and the dangers of material wealth.
The story portrays Tom Walker as a greedy and miserly man who is only interested in accumulating wealth and power, and is ultimately punished by the devil for his greed and avarice. This reflects the Puritan belief that material wealth is a temptation that can lead one away from the path of salvation.
Therefore, "The Devil and Tom Walker" reflects many of the Puritan beliefs and values that were prevalent in New England during the late 1700s, including the concepts of predestination, the eternal struggle between good and evil, the dangers of material wealth, the importance of repentance and redemption.

How is nominal scale type related to diversity? No links no trolls plzzzzzzzzzzz
Answer:
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless.
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. Some examples of variables that use nominal scales would be religious affiliation, sex, the city where you live, etc. Example. One example of a nominal scale could be "sex".
For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.

What causes decrease in genetic variation?
Genetic variation decreases as a result of inbreeding, genetic drift, restricted gene flow, and small population sizes.
There aren't many variations among individuals in a species with low genetic diversity since there aren't many different gene alleles present. This would imply that there are less chances to adjust to environmental changes. Due to habitat degradation, low genetic diversity is frequently observed.
The difference in DNA between individuals or communities is known as genetic variation. Mutation and genetic recombination are two of the many processes that cause genetic variation. Genetic variety is primarily caused by mutations, although it is also influenced by other processes including genetic drift.
