Answer:
hox genes are a subset of regulatory genes that encode transcription factors and they are important for embryonic development. they are activated by a cascade of regulatory genes and the proteins encoded by the early genes regulate expressions of later genes
Explanation:
No they release oxygen which consumers breath in and in return release carbon dioxide
Humans backing OFF. that saved them
<h2>
Answer</h2>
The right option is (A).
<h2>
Explanation</h2>
The RNA gets its information from DNA to synthesise the proteins. It is different from DNA also due to the difference in one nitrogen basis as uracil. The thymine, the nitrogen basis that is only present in DNA is replaced with uracil to form RNA coding. The uracil also contains the same features as thymine has in DNA strains. Uracil makes a double H-bond with the adenine but does not contain CH4 group which is present in thymine.
