Answer:
50% G+C will have a higher Tm
Explanation:
The Temperature of Melting (Tm) refers to the temperature at which 50% of double-stranded DNA (dsDNA) is changed to single-standard DNA (ssDNA). In the double helix of DNA, Adenine bases always pair with Thymine bases through two hydrogen bonds, whereas Guanine bases always pair with Cytosine bases through three hydrogen bonds. In consequence, a DNA molecule containing a higher GC content is more stable than another DNA molecule containing a lower GC content. The Tm can be calculated as follows = 2 °C(A + T) + 4 °C(G + C) = °C Tm (this equation is useful for oligonucleotides of 14 to 20 base-length).
Answer:
<h2>Apoenzyme
</h2><h2>Cofactors</h2>
Explanation:
Conjugated enzymes also known as holoenzyme. Simple enzymes consist of only protein alone but the Conjugated enzymes contain protein ( this portion is called Apoenzyme) and nonprotein molecules (this portion is called cofactor). Cofactor help enzymes in their action.
Enzymes are catalyst which increase the rate of a reaction by decreasing the activation energy.
Nectar attracts bees and other pollinators to the flowers and then the pollen gets stuck to the pollinator. Once the pollinator goes to a different flower, the pollen that was originally on the pollinator goes onto the present flower. That is how nectar helps flowers become pollinated
