What will happen if a nucleotide is deleted from a gene having 9 nucleotides in its transcriptional unit?
Correct answer: A. Change in Phenotype
- A. Change in Phenotype
- B. No change in Phenotype
- C. Synthesis of 3 amino acids.
- D. Synthesis of 4 amino acids.
Explanation
A deletion changes the DNA sequence by removing at least one nucleotide in a gene.Phenotypic effects of deletions depend on the size and location of deleted sequences on the genome. If the nucleotide is deleted this effect amino acid sequence thus primary secondary or tertiary structure is disturbed protein becomes non functional.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
