Answer:
It is usually easier to calculate an enzyme's reaction velocity from the rate of appearance of PRODUCT rather than the rate of disappearance of a SUBSTRATE. Enzyme activity is measured as an INITIAL reaction velocity, the velocity before much SUBSTRATE has been depleted and before much PRODUCT has been generated. It is easier to measure the appearance of a small amount of PRODUCT from a baseline of zero PRODUCT than to measure the disappearance of small amount of SUBSTRATE against a background of high concentration of SUBSTRATE.
<span>Translation
</span>Remember that transcription happens in the nucleus as it changes from DNA
to mRNA. In translation,
the mRNA first has to leave the
nucleus and go into the cytoplasm of the cell.
The process of translation actually occurs in the cell’s ribosomes.
<span>
</span>The process of translation uses the genetic code on the mRNA strand to
direct the construction (making) of a protein molecule. <span>
</span>1. A ribosome attaches to an mRNA
molecule in the cytoplasm.<span>
</span>2. As each codon passes through the
ribosome, tRNA molecules bring the matching amino acids into the ribosome. Each tRNA has a set of 3 unpaired nitrogenous
bases called an anticodon which matches up with the codon coming through the
ribosome. So one end of a tRNA has an
anticodon and the other end carries the amino acid which is how the code is
translated.<span>
</span>3. The ribosome and the rRNA
molecules it contains attach the amino acids together as they are being
translated. The protein chain will keep
growing until the ribosome reaches the stop codon on the mRNA. At that point, translation is done and the
ribosome lets go.

Answer:
c. Proteins
Explanation:
A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.
the correct arrangement of the above sentences is as follows: sentence 3- sentence 5- sentence 2- sentence 6- sentence 1- sentence 4.
