If the average length of a double helix in human chromosome is 3.9 cm, approximately how many base pairs are present in such chr
ikadub [295]

Answer:

The average length of a double helix in human chromosome whose length is 3.9 cm has approximately 114.7 million base pairs

Explanation:

Lenght of DNA = number of base pairs * distance between consecutive base pairs

The distance between two consecutive base pairs bonded by hydrogen bonds is 0.34 nm.

If the average length of a double helix DNA molecule in human chromosome is 3.9 cm, the average number of base can then be calculated using the formula below:

Average number of base pairs = length of DNA ÷ distance between consecutive base pairs

Average number of base pairs = 3.9 cm/ 0.34 nm = 0.039 m/ 0.00000000034 m

Average number of base pairs = 114705882.4

Therefore, the average length of a double helix in human chromosome whose length is 3.9 cm has approximately 114.7 million base pairs

serious [3.7K]

Answer:

The most correct option is carbohydrates & lipids

Explanation:

Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen [for example starch, (C₆H₁₀O₅)ₙ] while lipids generally contains carbon, hydrogen and oxygen [for example fatty acid, CH₃(CH₂)ₙCOOH] but could also contain other elements like sulphur and phosphorus.

Proteins are made up of building blocks called amino acids. Amino acids are made up of an amino group which consist of nitrogen and hydrogen. Hence, <em>proteins have a large number of nitrogen atoms thus not part of the answer.</em>

<em>Nucleic acids are composed of nitrogenous bases and phosphate groups and are also not part of the answer for this reason.</em>
