You need more context to answer this.
Bacteria that have
taken up the plasmid with antibiotic resistance
gene will grow in a medium laced with the particular antibiotic of interest. More
so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments
are used with selective media that only allows the bacteria with a particular characteristic
to grow.
Answer: Dominant allele codes for a functional protein. Recessive allele codes for a less functional or nonfunctional protein, or it does not code for any protein.
Explanation:
Alleles are different forms of a gene. There are two types, dominant and recessive allele. Heterozygous organisms have one of each, and the dominant allele is expressed. Homozygous organisms have either two dominant alleles or two recessive alleles.
<u>A dominant allele produces a functional protein</u>, even in the presence of a recessive allele, because only one copy of the allele is enough and it masks the effects of the recessive allele. This dominant trait is shown in individuals who are homozygous dominant or heterozygous,
<u>A recessive allele produces a less functional or nonfunctional protein, or it does not code for any protein at all.</u> A recessive allele does not become a trait unless both copies of the gene are present.
