Question

1. when dna coils it is called a what? *

adenine
amino acids
chromosome
codons
cytosine
dna
guanine
mrna
nucleotides
protein
thymine
transcription
translation
trna
uracil

Explanation:

To solve this, we analyze each option:

• Adenine, Cytosine, Guanine, Thymine, Uracil: These are nitrogenous bases (parts of nucleotides), not the coiled form of DNA.
• Amino acids: Building blocks of proteins, not related to coiled DNA.
• Codons: Triplets of mRNA bases, not coiled DNA.
• DNA: The molecule itself; coiling forms a higher - order structure.
• mRNA, tRNA: Types of RNA, not coiled DNA.
• Nucleotides: Building blocks of DNA/RNA, not the coiled structure.
• Protein: Product of translation, not coiled DNA.
• Transcription, Translation: Processes in protein synthesis, not the coiled form of DNA.
• Chromosome: DNA coils (along with proteins like histones) to form chromosomes, which are the condensed, coiled structures of DNA during cell division or for organization.

Answer:

C. Chromosome
