The fundamental physical and functional unit of heredity is the gene. DNA is the material that makes up genes. Some genes serve as blueprints for the production of proteins. Many genes, however, do not code for proteins. Genes in humans range in size from a few hundred to over 2 million DNA bases. Humans have between 20,000 and 25,000 genes, according to the Human Genome Project, an international research initiative that worked to ascertain the sequence of the human genome and classify the genes that it contains.
Each individual is born with two copies of each gene, one from each parent. The majority of genes are identical in all humans, but a small number of genes (less than 1% of the total) vary slightly. Alleles are variants of the same gene with minor variations in DNA base sequence. These minor variations contribute to the individuality of each person’s physical features.
Genes are given special names by scientists to keep track of them. Genes are given symbols, which are short combinations of letters (and sometimes numbers) that represent an abbreviated version of the gene name, since gene names can be long. The cystic fibrosis transmembrane conductance regulator, for example, is a gene on chromosome 7 that has been linked to cystic fibrosis; its symbol is CFTR.
Which of the following statements are correct :
linguistics fields Any of a variety of fields of research in which linguistic insights have been applied, such as sociolinguistics, which studies culture and how language is used in it. Psycholinguistics, for example, is concerned with the psychological and linguistic growth of children.
proficiency This, according to Chomsky’s Aspects of the Theory of Syntax (1965), is an individual’s abstract ability to speak the language that he or she learned as a native language during childhood. Nervousness, temporary memory loss, speech mistakes, and other causes have little bearing on a speaker’s capacity. These latter phenomena fall under the category of efficiency, which is described as the process of putting one’s skills to use in the act of speaking. Keep in mind that competence often includes the ability to determine whether or not a sentence is grammatically correct; this is a subconscious ability.
the situation A term that refers to the context in which a particular element (sound, expression, or phrase) occurs. The context can dictate the elements are present, in which case ‘co-occurrence constraints’ are used, for example. 1) In English, /r/ cannot follow /s/ in a syllable, e.g. */sri:n/ is not phonotactically permissible; 2) The progressive form cannot be used for stative verbs, e.g. We are aware that the German language is not well-formed in English.

A Gene Ontology (GO) annotation is a statement about a gene’s role. By associating a gene or gene product with a GO word, GO annotations are generated. These statements together make up a “snapshot” of existing biological understanding. As a result, GO annotations capture statements about how a gene works at the molecular level, where it works in the cell, and what biological processes (pathways, programs) it aids in.
A GO annotation is uniquely identified by four pieces of information. Although a curator may use additional components such as qualifiers and annotation extensions to imply more detail, an annotation must at the very least include:
Since various pieces of information about gene function can be developed to varying degrees, each GO annotation often refers to the evidence that supports it. The scientific literature, either directly or indirectly, supports all GO annotations in the end. Supporting evidence in GO is viewed as a GO Evidence Codes and either a written reference or a summary of the methods used to construct the annotation. The GO evidence codes identify the form of evidence and show how far the annotated argument is from direct experimental evidence, as well as whether the evidence was checked by a biocurator expert.

Which one of the following claims about a gene is true?
A gene can code for one or more proteins. B. During DNA replication, a gene undergoes crossing-over. C. A gene with a human and bacterial sequence that is very similar is most likely a recent mutation. D. A recessive gene is one that is found in a generation’s offspring. E. Genes can be found in introns, which are different versions of the same gene.
All of the following claims regarding mammalian meiosis are right. EXCEPT FOR: A. It occurs as a result of DNA replication. B. It is a factor in the generation of variance in offspring. C. It produces four gametes that are genetically similar. D. It’s only found in reproductive organs. E. It generates cells with haploid chromosome numbers.
