The correct answer is: silent mutation
There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:
1. Substitution-only one base is changed
• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon
• Missense mutations-when one nucleotide is substituted and a different codon is formed
• Silent mutations-when a nucleotide is substituted and the same amino acid is produced
2. Insertion- extra base pairs are inserted
3. Deletion- section of DNA is deleted
Answer:
If the owl is at the top only 10 units
Explanation:
Answer:
Non- targeted cell lacks intracellular receptor for these hormone.
Explanation:
Receptors that are found on the cell surface are called cell surface receptor and those which are found inside the cell are called intracellular receptors. Intracellular receptor binds to lipophilic molecules. Each receptor binds specifically to a particular ligand or signal molecule.
So even though testosterone and estrogen can diffuse in every cell they will only affect those cell which have specific receptor which can bind to these hormones and then regulate the transcription of a specific gene in the nucleus.
So only those cells will respond to testosterone and estrogen who have specific intracellular receptors for them.
