The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.
<h3><u>Explanation:</u></h3>
All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.
If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased.
So the disorder must be X linked disorder
Answer: I believe c is what you're looking for, D is also a viable option, but C is more likely.
Explanation:
In prokaryotes the 5' UTR is 3-10 nucleotides.
In Eukaryotes the 5'UTR is 100 to many thousand nucleotides long.
Explanation:
Leader sequence or 5' UTR starts at transcription site and ends at the initiation codon just one nucleotide away from it.
It is present in mRNA.
These are GC rich and form secondary structure, helps in protein synthesis.
Shine Dalgarno sequence in prokaryotes is an example of 5'UTR.
It acts as an entry point of ribosome.
