Answer:

"Viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it is a true statement.

Explanation:

The virus is an infectious agent which is not considered living either considered non- living. The virus particles contain the genetic material that determines the trait of a virus in the form of either DNA or RNA.

The virus which contains the RNA replicates themselves by fist converting their RNA into DNA by reverse transcriptase enzyme. Once the DNA is made, the DNA is incorporated in the genome of the host and the machinery of the host performs the replication, transcription and translation.

Thus, the selected option is true.

Artemon [7]

Answer:

The magnetic field is strongest at point C.

Explanation:

In a magnetic field, the center is known to be strongest region of the magnetic field while between the two poles outside the bar magnet are the weakest region.

Lines of the magnetic field are seen to be the densest even at the center of the magnetic field while between the poles outside the bar magnet, it is least dense.

A magnetic field is known to be a field which shows the magnetic impact and influence on electric charges, magnetic materials and electric currents.

One of the questions early geneticists had to answer was how only four nucleotides can specify placement of 20 amino acids in pr
jenyasd209 [6]

Answer:

<h2>Codon </h2>

Explanation:

The sequence of DNA is transcribed into mRNA, containing the sequence  for protein synthesis, protein is synthesized according to the codons in mRNA.  This sequence of nucleotide on DNA/ RNA is divided into a series of three nucleotide units, and one unit of three nucleotide is  known as codons.

There are overall 64 codons, 61 codons out of 64 codons, codes for overall 20  amino acids, and the remaining three  are stop codons.

These there codon do not code for any amino acid.

And these 61 codons, they  code for total 20 amino acids. So one amino acid can be coded by one or more than one codons.
