Why do multiple and lethal alleles often result in modifications of the classic Mendelian monohybrid and dihybrid ratios?
allochka39001 [22]

Answer:

Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.  

For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.

Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).  

Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.

For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1

How a change in glycoproteins affects a cell’s ability to maintain homeostasis
Licemer1 [7]

Explanation:

Most of the cell surface receptors and glycoproteins. These glycoproteins have active sites that recognize specific signals, like hormones, that initiate secondary signaling pathways inside of the cell, in response to the external signal. This is how cells respond to environmental stimuli.

If a change in glycoproteins makes them unable to bind signaling molecules (like hormones) or makes them permanently bind these molecules, there will definitely be a defect in how the cell responds to external stimuli.  The cell will be, for example, be unable to respond to insulin in case of elevated blood sugar levels as is the case with diabetics.

How are the based-pairing rules different for RNA then DNA
DedPeter [7]
The “bases” of RNA differ from those of DNA in that thymine (T) is replaced by uracil (U) in RNA. ... In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).
