Answer:
3rd generation = 2 Hybrid DNA molecules + 6 Light DNA
In Percentage 2÷8 × 100 = 25%
25% of the DNA are hybrid
Explanation:
Semi conservative model proposed by Watson and Crick states that one strand of the DNA comes from parent DNA which act as a template for the other newly formed strand.
First generation:
If cells containing 15 N DNA are transferred to a medium with only 14 N then in initial first generation two parent strands becomes separated and act as template for newly synthesized strands. this means that in first generation both DNA molecules are hybrid, one strand of 15 N DNA and other strand of 14 N DNA
Ist generation = 2 Hybrid DNA molecules
Second generation:
In Second generation these two hybrid molecules become unzip. Two strands are 15N and two strands are 14N. All these 4 strands act as template and 4 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 2 molecules of Light DNA.
2nd generation = 2 Hybrid DNA molecules + 2 Light DNA
Third generation:
In Third generation these two hybrid molecules and two light DNA molecules become unzip. Two strands are of 15N and six strands are of 14N. All these 8 strands act as template and 8 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 6 molecules of Light DNA.
3rd generation = 2 Hybrid DNA molecules + 6 Light DNA
In Percentage 2÷8 × 100 = 25%
25% of the DNA are hybrid
Historically, women and minorities have been underrepresented in the sciences because of sexism and racism, and an early lack of science education for both groups. Although there is still a gap, women and minority in the sciences are represented more than ever, although there's still a long way to go.
Answer:
Correct, It will help you proove your claim
Explanation:
Temperature should it be drawn to 600°-650° Fahrenheit for the newly made spring has been hardened
- Hammer, sear, and trigger are the three main parts of a trigger mechanism.
- . Single-stage trigger is used on the Winchester Model 94 and Marlin Model 336 rifle.
- Lapping is the process called that entails rubbing minute amounts of metal from surfaces that must be precision-finished.
- . Gray to dark blue color would be observe if we achieved the desired drawing temperature of 600-650° Fahrenheit.
- Thermocouple pyrometer is the most common instrument for measuring high temperatures in heat-treating furnaces.
- Cherry to bright cherry color would be observe by reaching the temperature of 1,400°-1,500° Fahrenheit.
- Once the newly made spring has been hardened 600° -650° Fahrenheit temperature would observe.
