Answer:
The answer is 1) a chromosome
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer:
nonsense codon; shift in reading frame; nonsynonymous codon.
Explanation:
The mutation that affects the single nucleotide of nucleic acid are called as point mutation. It includes substitution, insertion or deletion of single base pair.
- When a premature nonsense or stop codon is inserted in the DNA sequence nonsense mutation occurs such as UAU is replaced by UAA (stop codon).
- A single nucleotide is added or deleted (shift in reading frame) in frame shift mutation.
- The amino acid are changed because of change in codon (nonsynonymous codon) by missense mutation.
- The mutation does not change the codon thus does not change the amino acid (synonymous codon) and does not express it are called as silent mutation.
