During an enzymatic reaction, a molecule of binds to the enzyme and is broken down into one or more molecules of____, which are

Ugo [173]

During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.

<h3>What is substrate and product ?</h3>

While products can be produced at the end of the reaction, substrates are the reaction's initial raw material. The distinction between a substrate and a product is that a substrate is the substance used to initiate a chemical reaction, whereas a product is the compound formed when the reaction is finished.

<h3>What do you mean by enzymatic reaction ?</h3>

In an enzyme reaction, the free enzyme E binds to its substrate S to form the enzyme-substrate complex (C1), which is then catalyzed into the enzyme-product complex (C2), from which the free enzyme and product P are released: S + E ↔ C1 ↔ C2 → P + E. This is known as the "lock-and-key" model in enzymatic reactions. The great majority of cellular reactions are represented by this paradigm.

Thus from the above conclusion we can say that during an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.

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) <span>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: </span> $T = C*D$
⇒ $T = 10^{14}*12.42* 10^{-4} mi$
⇒ $T = 12.42* 10^{14-4} mi$
⇒ $T = 12.42* 10^{10} mi$
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 <em>twice </em>(because of stretch to the Sun and back, thus, <em>two directions</em>) of distance from <span>Earth to the Sun (ES) and :
Ratio: </span> $R= \frac{T}{2*ES}$
⇒ $R = \frac{12.42* 10^{10}mi }{2*(9.3* 10^{7}mi)}$
⇒ $R = \frac{12.42* 10^{10}}{18.6*10^{7}}$
⇒ $R = 0.6677* 10^{10-7}$
<span> ⇒ $R = 0.6677* 10^{3}$
</span><span> ⇒ [tex]R = 667.7
</span>Thus, 667,7 times will the <span>total DNA from the average human stretch from Earth to the Sun and back.</span>

What chromosome is a sex-linked trait located on?

Gelneren [198K]

Answer:

Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome.

What is the most appropriate method to prepare a sample of cheek cells for PCR?

Dmitry [639]

Answer:

Extraction of genomic DNA

Explanation:

Resuspend the cells(any number), smaller numbers also work, in 10-20 ul of TE buffer or milli Q water. boil for 5-10 min in a waterbath, quick chill, short spin. use the supernatant as a template for PCR.

If cells are very less, u can directly add cells to the PCR reaction without enzyme,boil for 5-10 min in a waterbath, let it cool slowly, short spin. Add enzyme to the supernatant and start the reaction at extension step followed by normal PCR reaction steps.
