Answer:

Below:

Explanation:

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produ
Ivanshal [37]

Answer:

Explanation:

The double-stranded DNA molecule has the  potential to store genetic information in either strand, although in  most organisms <u>only one strand is used to encode any particular gene</u>.  

The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).

Thus, genetic  information is expressed by transcription of the non-coding (template) strand  of DNA, <u>which produces an mRNA molecule that has the same sequence  as the coding strand of DNA</u>. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.

marysya [2.9K]

Answer:

523.035 km

Explanation:

It is given that, a distance of 325 miles is covered on a trip to Europe. In this problem, we need to find how many kilometers will you be traveling.

To convert 325 miles to km, we must know the conversion from miles to kilometers.

1 mile = 1.60934 km

For 325 miles, multiply it by 1.60934 i.e.

325 miles = (325 × 1.60934) km

= 523.035 km

Hence, you will be travelling 523.035 km on a trip to Europe.
