The answer is (b.) fertilization
The fertilization is the stage where the egg cell or the
so-called ovum fused with the sperm cell which eventually leads the development
of the embryo or the zygote. The Embryogenesis starts when the zygote undergoes
mitotic divisions or also known cleavage process.
Answer:
See the answer below
Explanation:
<em>The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.</em>
The problem of transporting the messenger RNA is solved by two features of the cell:
- The presence of pores in the nuclear envelop
- The presence of transport proteins in the nucleus
<u>The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP. </u>
A correct flow chart is DNA i.e., gene (transcription) >> mRNA + tRNAs (translation) >> amino acids or protein >> phenotype. It is the flow of the genetic information.
<h3>What is the flow of genetic information?</h3>
The flow of genetic information refers to the molecular process from DNA to the final phenotype (i.e., protein product).
During gene transcription, a particular fragment of DNA called gene is used as a template to generate an mRNA.
Subsequently, the mRNA serves as a template to generate a linear chain of amino acids, i.e., a protein, by a process called translation.
The final protein can be considered as the phenotype (in this case, the albinism trait) because it is the observable feature.
