Describe the effect on a protein if one or more amino acids are changed what is an example
hodyreva [135]

Answer: The effect will be either an abnormal protein, a non functional protein or a protein with altered function or functions.

Explanation: Every protein performs at least one specific function. Example is the case of sickle cell disease where a protein called haemoglobin which is responsible for oxygen transport in the body is mutated. In the sickle haemoglobin, valine replaces glutamate at position six of the two beta chains. Haemoglobin is a protein with four subunits made up of two alpha chains and two beta chains. The substitution of glutamate residue withwresults valine results in the haemoglobin having low affinity for oxygen binding and consequently, inefficient supply of oxygen to the cells.

A scientist is studying fruit fly wings. Straight wings are dominant, and curly wings are recessive. Which statement correctly d
svetoff [14.1K]
The offspring will have one allele for straight wings and one allele for curly wings.


Explanation:

Let W be straight wings (big letter for dominant allele)
Let w be curly wings (small letter for recessive allele)

Each fly has two alleles.
If a parent is true breeding, it only has one type of allele.
Parent 1 = WW (straight wings)
Parent 2 = ww (curly wings)

Cross the parents: WW x ww in a Punnett square (see photo below)
This is the F1 generation (generation produced by crossing the first parents).
There are only Ww offspring.

Therefore,
The offspring will have one allele for straight wings and one allele for curly wings.
