The correct sequence between genes and their phenotypic expression is
a) RNA-DNA-protein-trait
b) DNA-RNA-protein-trait
c) Protein-DNA-RNA-trait
d) trait-DNA-RNA-protein
I think it is either b or d but do not know if the trait is at the beginnig or end...
Once translated, the polypeptide typically undergoes substantial alteration that results in
a) excision of introns
b) addition of poly(A) tail
c) formation of peptide bonds
d) a change in its primary structure
e) the synthesis of amino acids
I think it is d but not 100% positive.

The correct sequence between genes and their phenotypic expression is:
b) DNA-RNA-protein-trait
The correct answer is b) DNA-RNA-protein-trait. Genes are composed of DNA, which is transcribed into RNA through a process called transcription. This RNA, specifically messenger RNA (mRNA), is then translated into proteins through a process called translation. These proteins ultimately determine the traits or phenotypic expression of an organism.
Once translated, the polypeptide typically undergoes substantial alteration that results in:
d) a change in its primary structure
The correct answer is d) a change in its primary structure. After translation, the polypeptide undergoes various post-translational modifications, including folding, addition of chemical groups, cleavage of specific regions, and other modifications. These alterations can result in changes to the primary structure of the polypeptide, which is the linear sequence of amino acids in the protein.
To determine the correct answers to these questions, we need to understand the process of gene expression.
For the first question, the correct sequence between genes and their phenotypic expression is: b) DNA-RNA-protein-trait. Gene expression starts with DNA being transcribed into RNA through a process called transcription. This RNA molecule is then translated into a protein in a process called translation. Finally, the protein synthesized from the RNA carries out a specific function or contributes to a particular trait.
Regarding the second question, once the polypeptide is translated, it undergoes various modifications. The correct answer is d) a change in its primary structure. After translation, the polypeptide can undergo post-translational modifications, such as folding, phosphorylation, glycosylation, or cleavage, which results in changes to its primary structure. This can affect its functionality and stability.
Remember, understanding the fundamental concepts and processes involved in these questions can help you arrive at the correct answers.
