If there are 999 bases in an RNA that codes for a protein with 333 amino acids, and the base at position 901 is deleted, such that the length of the RNA becomes 998 bases, how many codons will be altered?
Correct answer: B. 33
- A. 11
- B. 33
- C. 333
- D. 1
Explanation
In RNA, each codon is made up of three nucleotide bases, and each codon codes for a specific amino acid. So, if you delete a single base, it will result in a shift in the reading frame and potentially change the codons downstream from the deletion point. Therefore, a deletion at position 901 will affect 33 codons.

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.
