Which process is the first step of protein synthesis? a. transcription b. replication c. conjugation d. translation

Correct A. Transcription

Explanation:

The first step in protein synthesis is transcription. In this step, the two strands in double DNA helix are separated and one of them is used as a model: an RNA sequence is synthesized from the original DNA.

Then, in a second step, this mRNA (messenger ribonucleic acid) will be used by ribosomes to make an amino acid sequence (primary protein structure).

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
