Answer:
Explanation:
It certainly isn't the last one. A theory is close to a guess. It fits all the known facts, but there is usually something missing. If someone figures out what is missing, usually by experiment, then the theory become a fact.
The rest of them (1 2 an 3) can all be true. 3 is the least viable. You have to be able to come up with a counter example to reject a theory.
I'm not sure about 2. New phenomena can still be part of current theories. Reluctantly, I wouldn't choose 2 because
1 is the best answer of a very poor lot. Do not be surprised if you use it, that it turns out to be wrong.
Protein synthesis is a biological process whereby individual cells build their own specific proteins. In the process of protein synthesis, it involves both ribonucleic acid (RNA) and (deoxyribonucleic acid) DNA. This process initiates in cell’s nucleus whereby some specific enzymes unwind the needed part of DNA and makes it accessible and a copy of RNA is made. In transcription DNA double helix which is used as a template is where information of DNA is copied to RNA as one strand.
RNA which are sent to cytoplasm helps to bring components which require for protein synthesis for example ribosomes, amino acids, transport RNA. mRNA is a messenger which is produced in the nucleus when a copy of RNA of protein genetic information encodes in DNA molecule. mRNA exits nucleus and goes into cytoplasm then it interacts with cellular structures called ribosomes and functions as cell’s assemblers in the process of protein synthesis.
RNA molecule or rRNA and proteins are contained in ribosomes whereby rRNA is organized into subunits and mRNA binds to one of the ribosomes sub-unit. mRNA interacts with ribosome sub-unit and makes the approach of another RNA molecule known as RNA or tRNA. tRNA possess a sequence of three bases or anticodon which corresponds codon within the mRNA sequence where elongation takes place. If matching of anticodons of tRNA is found, tyrosine then forms a peptide bond. Amino acids are hydrolyzed from tRNA when protein synthesis is terminated after mRNA is reached

Explanation:
DNA is the one responsible for character or trait transfer because it contains genes.
There are genes for sperm and these sperms are for reproduction.
Adenosine Triphosphate. Adenosine triphosphate, or ATP, is the primary source of energy in both plant and animal cells. ATP is a nucleotide that is the basis for all cell reactions, including the reactionary process of converting food molecules into energy.Aug 7, 2017
