aliya0001 [1]

Answer: C) the genes of this phage were made of DNA.

Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.

How is energy extracted
Margarita [4]

Answer:

Mark me as a Brainliest Please :)

Explanation:

The same principle works in all three cases, which is, the energy becomes heat and is extracted with the help of turbines in the same way that fossil fuels are burned. An electron-emitting neutron is equivalent to releasing kinetic energy. Histamine is a hydrogen atom with a helium nucleus.

D) During Transcription, a nucleotide has been deleted. Explain the effect this will have
valkas [14]

Answer:

this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence

Explanation:

During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.
