Answer: (A) Genetic changes can be designed to make cows yield more milk.
Explanation: Milk yield per cow has more than <u>doubled</u> in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation due to genetic changes. <u>This shows that genetic changes to make cows yield more milk has already occurred.</u>
D is the answer because the bacteria will be able to produce a functioning protein
X-ray crystallography, was the tool
To begin, you have to know what meiosis is. Meiosis is when a cell breaks into four daughter cells (like mitosis but with two extra daughter cells). Those four cells are still part of the parent cell, so they retain the genetics of the parent cell but split-up. So those cells are part of the foundations of the genetic build-up of the offspring.
In negative control, a gene is switched off when a regulatory protein binds to DNA and shuts down transcription.
