A gene for microtubule proteins is being made in a cell. How can mRNA represent an exact copy of that gene

Answers

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.

How does the Devil and Tom Walker reflect Puritans

Answers

"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.

What causes decrease in genetic variation?

Answers

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.

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.

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%

Answers

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.

The 1:2:1 genotypic ration dictates the law of are is homozygous dominant, heterozygous dominant and homozygous recessive.

A 1:2:1 genotypic ratio is a ratio of alleles that is found in a monohybrid cross. A monohybrid cross is a type of genetic cross in which only one trait is being studied. In a 1:2:1 ratio, the first number represents the homozygous dominant genotype, the second number represents the heterozygous genotype, and the third number represents the homozygous recessive genotype. This ratio can be found by using the Punnett square method.

This generally represents the genetics, of the first generation of the monohybrid cross made between the pea plant showing dominant and recessive traits. Such that dominant parent was homozygous dominant and recessive parent was homozygous recessive.

If a snake enters the board on an edge square, we want to catch it at a different exit square on the board's edge. The snake is familiar with the board and will take the route to the nearest reachable exit, in terms of the number of squares it has to move through to get there.
