Answer:
The correct answer would be B) The complementary base pair rules.
DNA serves as the genetic material in most of the living organisms and is transmitted from parents to their offspring.
It is like blue print of the cell which contains all the necessary information required for the functioning and regulation of cell in the form of nucleotide sequences.
Generally, DNA consists of two strands which are complementary in nature i.e. purine base pair with its specific pyrimidine (adenine always base pair with thymine and guanine always base pair with cytosine).
This property of DNA is of utmost importance in the process of DNA replication as daughter DNA strand is formed on the basis of complementary base pair of the template strand.
It ensures that correct DNA sequence is produced for transmission to the offspring or daughter cell.
Answer:
The correct answer is - regulation of the heavy metal and their toxicity.
Explanation:
Metallothionein is a group of cysteine-rich, small in size, and highly conserved proteins that bind to various metal ions and regulate their activity or toxicity in transcriptional level.
Metallothionein IIA is one of the metallothioneins that binds to heavy metal and helps cells to be protected from the toxicity of these heavy metals. These proteins are present in almost every eukaryotic organisms virtually. These proteins are highly induced to express highly in the present of heavy metals.
Thus, the correct answer is - regulation of the heavy metal and their toxicity.
The upper part of graft combination is called scion.
Answer:
Recessive alleles are usually represented by lowercase letters and require two copies to be expressed
