Experiments using "optical tweezers" measure the elasticity of individual dna molecules. for small enough changes in length, the elasticity has the same form as that of a spring. a dna molecule is anchored at one end, then a force of 1.5 nn (1.5 x 10-9 n) pulls on the other end, causing the molecule to stretch by 5.0 nm (5.0 x 10-9 m). what is the spring constant of that dna molecule?

The spring constant of DNA molecule is

Explanation:

As we know ,

Formula for spring constant

Where,

Force exerted on the DNA molecule in Newton

spring constant in

displacement in meters

Substituting the given values in above equation, we get -

Thus, the spring constant of DNA molecule is

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
