Answer:
sex-linked- recessive
Explanation:
Sex linked recessive are those traits which are expressed even if one copy of the defective allele are present. They are passed from parents to offspring through X or Y chromosomes.
These disorders are more prevalent in men than women because women have two X chromosomes while men have only one. Females can also get X-linked disorder but they are very rare because female needs two copies of defective gene to develop disorder while men need only one.
For example: As you can see in the example image the gene is passed in daughters too but mostly they are carriers but men develop disease because they have only defective X chromosome that contain defective gene and no counter part to lower its effects.
One of the common x linked disease is hemophilia. You can see the pedigree of Hemophilia that men are getting more effected than women.

Answer:
C) 30,000
Explanation:
According to the given information, the bacterial mRNA consists of about 800 nucleotides. Three consecutive nucleotides together make one genetic codon which in turn codes for one specific amino acid in the protein encoded by this mRNA.
So, an mRNA with 800 nucleotides will have total 800/3 = 266.67 or 266 genetic codes. The protein encoded by this mRNA would have a total of 266 amino acids.
Given that one amino acid imparts 110 units to the molecular weight of the protein, the protein with 266 amino acids have the molecular weight= 266 x 110 = 29260, that is about 30,000.
