Answer:
Explanation:
The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.
Answer:
The correct answer would be - D. the distribution of alleles in a population.
Explanation:
Allele frequency in population genetics is the term used to provide the amount of the different alleles in particular loci. In other words, it is the distribution of alleles in a population.
The term allele frequency refers to the fraction of the copies of the gene of the alleles in a known population. It can be calculated by the number of allele present of interest divided by total number of alleles in a population.
Answer:
<h2>1. unconditioned stimulus, </h2><h2>2. loud noise</h2>
Explanation:
Such type of stimulus that is trigger by the neutral in nature is called a conditioned stimulus such as the sound of the bell and some other. Such type of stimulus that is biologically potent is called an unconditional stimulus such as the taste of food and some other things. When the biologically effective stimulus is used with neutral stimulus then the classical conditions are formed that are used in the learning process.
