Answer: Environmental experience
Explanation:
The embryonic stage lasts approximately 4 week(s), beginning at conception. Details about stages of development can be found below.
<h3>What are the stages of development?</h3>
The stages of development of a human is summarized into four stages as follows:
- Embryonic stage
- Germinal stage
- Fetal stage
In the embryonic stage of development, which occurs after conception, the baby is called an embryo. Embryonic stage lasts 4 weeks.
During the embryonic stage, the cells of the embryo (called embryonic stem cells) multiply and develop. They become the hundreds of different types of cells needed to make a whole human body.

Ans.
The Sanger sequencing or chain-termination method for sequencing involves use of ddNTPs (dideoxyribonucleotide triphosphates) to identify the sequence of nucleotides in a DNA segment. The ddNTPs are nucleotide derivatives that lack both the 2'- and 3'-hydroxyl group, hence called dideoxyribonucleotides. When a ddNTP is added to a growing chain of DNA, absence of 3'-hydroxyl group leads to termination of growing chain as this ddNTP cannot make phosphodiester bond with a NTP and DNA sequence can be identified.
Thus, the correct answer is option C).
