In a desert, the climate is “hot” and “dry”.
Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.
Explanation:
Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.
Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.
The comparison of dominance and epistasis give the following information:
- Dominance involves allelic suppression while epistasis involves non-allelic suppression.
- Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
- In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant non allele is suppressed.
- The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.
Question:
The organelle shown consists of a stack of flattened membranes.
What is the primary function of this organelle?
- attaching amino acids to tRNA molecules
- long-term storage of molecules in the cell
- production of large and small ribosomal subunits
- repackaging proteins for export from the cell
Answer:
- repackaging proteins for export from the cell
Explanation:
The organelle consisting of a stack of flattened membranes is the Golgi apparatus.
The Golgi apparatus is like the packaging centre of the cell. It modifies, sorts, and packages proteins and from the endoplasmic reticulum to be stored in the cell or released outside the cell
Answer:
Glucose is stored in our liver as a monomer sugar.
