What are the subunits caalled that make up dna?

1 answer:

8 0

The subunits are the sugar-phosphates and nucleotides (adenine, guanine, cytosine and thymine for DNA, adenine, guanine, cytosine and uracil for RNA). The sugar-phosphate backbone is the out edge of the twisted "ladder" you typically see in drawings of DNA and RNA. It is what holds the molecule together.

The number of cells in an average-sized adult human is on the order of 10^14 cells. Use this information, and the estimate that

KengaRu [80]

IF:
Number of cells: $C = 10^{14}$
DNA lenght: $D = 2m = 12.42 * 10^{-4} mi$
Distance from Earth to Sun: $ES=93000000 mi = 9.3* 10^{7}mi$

Then:
a) Over how many miles would the total DNA from the average human stretch?
The answer is product of multiplication of the number of cells (C) and the DNA length (D):
Total DNA: $T = C*D$
⇒ $T = 10^{14}*12.42* 10^{-4} mi$
⇒ $T = 12.42* 10^{14-4} mi$
⇒ $T = 12.42* 10^{10} mi$
The total DNA from the average human will stretch $12.42* 10^{10} mi$

b) How many times would the total DNA from the average human stretch from Earth to the Sun and back?
The answer is concluded from the ratio of the total DNA length (T) and the twice (because of stretch to the Sun and back, thus, two directions) of distance from Earth to the Sun (ES) and :
Ratio: $R= \frac{T}{2*ES}$
⇒ $R = \frac{12.42* 10^{10}mi }{2*(9.3* 10^{7}mi)}$
⇒ $R = \frac{12.42* 10^{10}}{18.6*10^{7}}$
⇒ $R = 0.6677* 10^{10-7}$
 ⇒ $R = 0.6677* 10^{3}$
 ⇒ [tex]R = 667.7
Thus, 667,7 times will the total DNA from the average human stretch from Earth to the Sun and back.

What is a distinction that can be drawn between macroevolution and microevolution?

nikitadnepr [17]

Microevolution refers to changes in the genetic pool of a species population. The changes in the genes (probably gene and allele frequencies) are observed over short time periods hence are small changes. This is in comparison to macroevolution that observes huge changes over longer time periods in the population that warrant that the new populations is considered to be a new species
