Briefly explain how genes affecting a polygenic characteristic are located with the use of QTL mapping.

Answers

Answer 1

Answer:

QTLs can be identified by using molecular markers associated with the variation of the trait

Explanation:

A Qualitative Trait Locus (QTL) is a chromosomal region correlated with the variation of a quantitative trait, i.e., a phenotypic trait controlled by many genes. QTL mapping refers to the identification of QTLs associated with a particular trait. In QTL mapping, molecular markers (i.e., small and identifiable DNA fragments) are used to develop genetic linkage maps which are further used to discover QTLs. This technique (QTL mapping) consists of evaluating the phenotypic segregation of the trait in the progeny by statistically correlating phenotypes with patterns of genetic segregation (segregation of the molecular markers).

Answers

Answer:

To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data

Explanation:

The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.

b. lamellae, canaliculi
c. osteons, lamellae
d. Haversian canals, lamellae
e. none of the above

Answers

Answer:

The correct answer is c. osteons, lamellae

Explanation:

An osteon is the basic functional unit of the cortical bone of a tubular bone. An osteon consists of a central canal that contains two vessels of Havers. Concentric bony laminae are arranged around this canal. These lamellae consist of bone cells and the surrounding base substance. Between the Havers canals there are Volkmann canals that connect the Havers canals. The construction of the cortical bone in these functional units has not yet been fully clarified. In general, it is assumed that these structures serve primarily to deliver tissue and signal transduction. This structure is also supposed to serve the stability and adaptability of the bone.

Working with all chemicals carries some level of health risk, and modern society is dependent upon thousands of chemicals to maintain our standard of living. Therefore it is not reasonable to eliminate all chemical related health risks because that would require we stop using chemicals like cleaning supplies, gasoline, and fertilizers.

Molecules before and after a chemical reaction

Chemical reactions are takes place when chemical bonds form between molecules and atoms of substances. There are two-part to any chemical equation: part before the chemical reaction and after the chemical reaction.

In the part before the chemical reaction starts, there are molecules of the substance is called reactants that react with one another in chemical reaction and form or break chemical bonds of molecules. Products are newly formed substances by forming bonds in a chemical reaction.

What is a Chemical reaction?

A chemical reaction may be defined as a mechanism that significantly directs the chemical transformation of one set of chemical substances or molecules to another. This process of chemical transformation utilizes numerous catalysts to enhance the rate of reaction.

The amount or number of chemical substances or molecules that are present before the progression of reaction are known as reactants.

While after the successful progression or completion of a specific chemical reaction such reactants are performed into another, these substances or molecules are known as products.

Both the molecules of reactants and products possess some sorts of chemical identity in order to distinguisg from each other.

Therefore, Reactants and products are the names that we call the molecules before and after a chemical reaction respectively.

This fossil evidence suggests that

Answers

Answer:

millipedes were the first of these animal groups to evolve.

Explanation:

Fossils are structural remains of animals from the past. As these animals die, it takes years for the remains to be buried.

The millipedes are at the lower layer of the rock, next to insects, amphibians, and then rodents. This shows that millipedes existed and evolved before the rest of the found animal fossils.
