QUESTION 39
Which of the following is correct about two normal alleles of gene 'A' (i.e. 'A' and 'a')?
They have different locations on a single cs type
They are located on different cs types
They have slightly different sequences, but produce functionally compatible products.
They have different sequences, but produce identical products
They have identical sequences, but produce different products.
A.They have different locations on a single cs type
B.They are located on different cs types
C.They have slightly different sequences, but produce functionally compatible products.
D.They have different sequences, but produce identical products
E.They have identical sequences, but produce different products.
Explanation / Answer
Answer: Option C is correct.
Explanation:
Alleles = Alternative forms of a gene
Alleles = Sequence variant forms of a gene
Alleles are located at the same location on different chromosomes.
The dominant allele and recessive alleles exhibit sequence variation and often produce functional products that vary in their activity.
The difference in the activity depends upon the nature of and extent of the sequence variation.
