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).
The answer is force because the earthquake is shaking so the answer should be correct. <span />
to make ATP, H+ ions will flow through the ATP synthase. this movement through ATP synthase will create enough energy for ATP to be formed.
Answer:
Male-
The functions of the male reproductive system include producing and transporting sperm, ejaculating sperm into the female reproductive tract, and producing and secreting male hormones. Most of the male reproductive system is located outside of the body.
Female-
The main function of the female reproductive system is to produce eggs (ova) to be fertilised, and to provide the space and conditions to allow a baby to develop. In order for this to happen, the female reproductive system also has the structures necessary to allow sperm from a man to meet the ova of a woman.
