which piece of DNA would have the highest tm one with a cytosine plus guanine comment at t 30% or a cystonie plus guane content

erik [133]

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 site where the more movable end of a muscle attaches is the question 3 options: origin insertion belly fascicle

Lilit [14]

The correct answer is the insertion.
Insertion is the attachment site of the muscle end that does move when the muscle contracts. On the other hand, the origin is the attachment site that does not move during contraction (end of the muscle is fixed).

true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thor

faltersainse [42]

The thorax is a very vital and important organ in the human body.

It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.c

It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases.

When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases.

Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law.

Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.

Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.
