Spindle Fibres are those structures which move chromosomes only during cell division.
And these spindle fibres are formed by the command of centrioles which during the process move to the on the opposite poles and helps the cell to prepare for division.
The natural element _IODINE_ is important in the synthesis of thyroid hormone; lack of it will lead to a goiter.
Answer:
The codon length would not change.
Explanation:
Codons have 3 bases and normally the DNA has 4, each codon counts for a single amino acid. There are 64 possible codon variations which can be calculated by 
.
If there were 6 bases in the DNA than there would be 
codon variation that correspond to the same 20 amino acids but the codon lengths would still be the same.
I hope this answer helps.
