Which part of a DNA molecule is responsible for the direct coding of specific traits in anorganism?
Anastaziya [24]

The part of a DNA molecule responsible for the direct coding of specific traits in an organism is the nucleotide sequence.

<h3>How is a DNA molecule structured?</h3>

The DNA molecule is the biological molecule that stores genetic information in living organisms.

The DNA molecule is made up of three major components in its structure:

  • Five carbon sugar
  • Nucleotide bases
  • Phosphate group

The five carbon sugar is deoxyribose while the nucleotide bases are four in number as follows:

  1. Adenine
  2. Guanine
  3. Thymine
  4. Cytosine

These nucleotides are responsible for the direct coding of specific traits in an organism.

Enzymes that add ubiquitin to proteins have been found in the nucleus of eukaryotic cells. These enzymes would be most likely to
Kobotan [32]

Answer:

causing degradation of transcription factors and changing which genes are expressed

Explanation:

Ubiquitination  (addition of ubiquitin to a protein) is the first step in protein degradation process, and it directs  protein to the proteasome for degradation. This process involves three steps with specific groups of enzymes to perform them, which are activation with ubiquitin-activating enzymes, conjugation with ubiquitin-conjugating enzymes and ligation with ubiquitin ligases. These enzymes would be most likely to regulate gene expression by causing degradation of transcription factors and changing which genes are expressed.
