Question

I will give fan and medal!

Which statement describes the relationship between chromosomes, genes, and alleles?

A. Genes bind to sites on a chromosome. These sites are called alleles.

B. Alleles move genes to a specific location on a chromosome.

C. Alleles cause mutations, which are genes on part of a chromosome.

D. Alleles are different variations of a gene. Genes are the specific sections of a chromosome.

Answer 1

I think it's B

I think it's D?

Answer 4

Chromosomes are found in the nucleus. Chromosome is composed of chromosome and carries the genes in a linear sequence. Genes are the hereditary material composed of DNA and are responsible for the characteristics of individual. A gene occupies a specific position on a chromosome. Allele is alternative form of a gene. In case of diploid cell there are two allele of one gene, one from father and another from mother. In these one is dominant (express character) another is recessive (suppress character). These genes have specific nucleotide sequence which form triplet to code for protein. So the gene bears the information for the production of proteins. The characteristics which are expressed and can be seen by eye or felt by behavior of a organism or human is called the phenotypic expression or phenotype like the blond hair color is a phenotypic expression. The genetic information’s which are carried by the Gene for the phenotypic expression is called the genotype like the information of the nucleotide sequence that is responsible for the blond color is the genotype of that phenotype or the characteristics.
