How does transcription work

1 answer:

8 0

“Transcription takes place in the cytoplasm (prokaryote) or in the nucleus (eukaryote). The transcription is performed by an enzyme called RNA polymerase. ... Binds these new RNA nucleotides together to form a complementary copy of the DNA strand (mRNA) Stops when it encounters a termination sequence of bases (stop codon)”

Hope this helped.

Harold Reese must choose between two bonds: Bond X pays $95 annual interest and has a market value of $905. It has 13 years to m

Serga [27]

Answer:

Explanation:

current yield of bond x = annual interest/market value

current yield of bond x = 95/905

current yield of bond x = 10.50%

current yield of bond Z = annual interest/market value

current yield of bond Z = 85/910

current yield of bond Z = 9.34%

Bond X should be selected based on current yield

Approximate yield to maturity = (Annual Coupon + (Maturity value - Current price)/period)/ ( (Maturity value+ Current price)/2)

Approximate yield to maturity = (85+ (1000-910)/5)/((1000+910)/2)

Approximate yield to maturity = 10.79%

Exact yield to maturity = rate(nper,pmt,pv,fv)

Exact yield to maturity = rate(5,85,-910,1000)

Exact yield to maturity = 10.93%

Yes , answer would changed between parts b and c of this question as A drawback of current yield is that it does not consider the total life of the bond .

one mole of sodium chloride is added to 100 ml of water in beaker a. one mole of glucose, c6h12o6, is added to 100 ml of water i

Viefleur [7K]

Twice as much more will the freezing point of water be lowered in beaker a than in beaker b.

<h3>What determines freezing point?</h3>

A liquid's freezing point rises if the intermolecular interactions between its molecules are strong. The freezing point, however, drops if the molecules of inter - molecular are minimal. The process through which a substance transforms from a liquid into a solid is known as freezing.

<h3>How significant is freezing point?</h3>

Freezing points play a big role in occupational safety. A chemical may perhaps turn harmful if held below its freezing point. A critical safety benchmark for assessing the effects of worker exposure to cold environments is the freezing point.

All the oxides of nitrogen have positive values of G at 298K but only one common oxide of nitrogen has a positive S identify tha

Maurinko [17]

Answer:

The common oxide of nitrogen that has a positive ΔS°f is nitric oxide (NO)

Explanation:

Without reference to thermodynamic data, we have;

1) N₂ (g) + O₂ (g) ⇄ 2 NO (g)

1 unit of N₂ + 1 unit of O₂ (total of 2 units) gives 2 units of NO, (Increase of +0 disorder)

∴ΔS°f = +ve

2) 2NO + O₂ → 2NO₂

2 unit of NO + 1 unit of O₂ (total of 3 units) gives 2 units of NO₂, (Decrease of disorder)

∴ΔS°f = -ve

3) N₂ + 1/2 O₂ → N₂O

1 unit of N₂ + 1/2 unit of O₂ (total of 1+1/2 units) gives 2 units of NO₂, (Decrease of disorder)

∴ΔS°f = -ve

4) 4 NO₂ + O₂ → 2N₂O₅

4 unit of NO₂ + 1 unit of O₂ (total of 5 units) gives 2 units of N₂O₅, (Decrease of disorder)

∴ΔS°f = -ve

5) NO + NO₂ ⇄ N₂O₃

1 unit of NO + 1 unit of NO₂ (total of 2 units) gives 1 unit of N₂O₃, (Decrease of disorder)

∴ΔS°f = -ve

Therefore, the common oxide of nitrogen that has a positive ΔS°f without reference to thermodynamic data is nitric oxide NO.

Sulfur dioxide So2 is present in our atmosphere and is used as a preservative in foods. Is it possible to use the common charges

telo118 [61]

Answer:

Your question is not interpreted very well, but as regards what is observed, SO2 is not the formula for sulfur oxide, the formula for sulfur oxide is SO since the valence used in sulfur would be +2 and oxygen -2 therefore the sum of these valences would be equal to zero, therefore it would be the correct thing considering the true equation as SO

Explanation:

There are also sulfur dioxide, or sulfur trioxide, which is usually used in the formation of tertiary salts such as copper sulfate.

sulfur trioxide and sulfur dioxide are synonymous with sulfate or sulphite
