Andrews [41]

Answer:

Hydrogen Bonds

Explanation:

In the polymerase chain reaction (PCR) the temperature rises to 90 ° C - 95 ° C, to break the hydrogen bonds, which are the types of bonds responsible for pairing the two strands of DNA, this process is known as denaturation of DNA.

The DNA is extremely stable, due to a large number of bonds (hydrogen bonds) that form between the two strands. If the temperature decreases, these bonds will begin to recompose, until the DNA returns to its original state

Do you think the shape of orchids is pure Mendelian inheritance, or is it more complex?
Mandarinka [93]

The genetic base of the shape of orchid is very complex.

Mendelian traits are described as simple traits determined by one gene. The different alleles of the gene contribute to the difference in the trait. This is true for some traits in plants, animals including humans and other organisms, but not for the shape of orchids.

The shape of orchid flowers is determined by the ABCDE group of genes that are responsible for the body plan in plants. These genes are the equivalent of HOX genes of animals.

The protein products of different genes of the ABCDE group interact with each other in complex ways creating different shapes of orchids.
