Answer:
Endoplasmic reticulum.
Explanation:
Protein synthesis, sorting and transport is the important mechanism for the synthesis of protein in the body and the transport of the protein to its specific site or organ. The protein must reaches to its final destination for its proper functioning.
KDEL ( K- leucine, D is aspartic acid, E is glutamic acid and L is lysine ) is the stretch of a specific amino acid that are responsible for the protein molecule to target at its specific site. KDEL is specific for the transport of peptides to the endoplasmic reticulum.
Thus, the correct answer is option (A).
binary fission?
In binary fission, the parent is split into two daughter cells, each genetically identical while receiving a copy of DNA
C
in the first paragraph a fact is challenged
and the second one provides an example
Answer: The man's genotype is WwLt while the woman's genotype is wwLt.
Explanation: From the information given above, W is the allele for wide jaw, w is the allele for narrow jaw, W is completely dominant to w, L is the allele for large teeth while t is the allele for small teeth.
The man has wide jaw but his mother has a narrow jaw, since narrow jaw is recessive the man must have inherited one recessive allele for narrow jaw from his mother who has two recessive alleles for narrow jaw. Therefore since the man has wide jaw, he must be heterozygous for wide jaw (having one dominant allele for wide jaw and one recessive allele for narrow jaw), his genotype for wide jaw is therefore Ww. The man is heterozygous for teeth size, this means that he has one dominant allele for large teeth and one recessive allele for small teeth. His genotype for teeth size is Lt. Therefore the man's genotype is WwLt.
The woman has a narrow jaw, this means that she has two recessive alleles for narrow jaw (ww) and she is heterozygous for large teeth size, this means that she has one dominant allele for large teeth and one recessive allele for small teeth (Lt). Therefore, the woman's genotype is wwLt.
