Question

which of the following statements concerning genes are true? select all that apply. check all that apply a gene is a segment of dna that determines a certain trait.a gene is a segment of dna that determines a certain trait. an allele is a variation of a given gene. an allele is a variation of a given gene. genes contain information that codes only for proteins involved in the regulation of gene expression.genes contain information that codes only for proteins involved in the regulation of gene expression. genes are not responsible for the expression of traits.genes are not responsible for the expression of traits. allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.

Answer 1

A gene is a DNA segment that determines traits, an allele is a variation of a gene, and allele variations can alter protein structure and function, affecting the traits of an organism.

Step-by-step explanation:

Regarding the statements concerning genes and alleles:

• A gene indeed is a segment of DNA that determines a certain trait, which is related to the coded instructions for making specific proteins within an organism.
• An allele is a variation of a given gene, representing different forms a gene can have.
• Genes contain information that codes not only for proteins involved in the regulation of gene expression but also for a variety of proteins that carry out diverse functions in an organism.
• It is not true that genes are not responsible for the expression of traits; genes are fundamental in determining the traits of an organism through the production of proteins.
• Allele variations are indeed due to small changes in the nucleotide sequence within a gene that can sometimes alter the structure and function of a protein.
