Answer:
Roots help a plant grow by absorbing the water and nutrients from the soil
Explanation:
The following are the environmental factors that can damage genes that code for these enzymes. radiation from sun, various chemicals and x-rays. these agents are referred to as environmental mutagens. they result to changes in the genetic make up of the organism and in turn affect the production of enzymes. enzymes are protein in nature and once the DNA has been compromised their production is affected. in most cases mutated DNA produces enzymes with lost or abnormal function.
A bacterial promoter sequence must be included. The coding exons control the actual production of the protein that the gene codes for; meanwhile, the promoter sequence serves to initiate transcription of the specific genes. Promoters are included upstream of the DNA molecule at the start site of the gene.
Haploid generations produce gametes through mitosis.
