Describe the role of complementary base paring in DNA replication, transcription, translation and hibridization probe technique.

Expert Solution

COMPLEMENTARY BASE PAIRING:-
(A) DEFINATION:- the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA.
-guanine is the complementary base of cytosine.
- adenine is the complementary base of thymine in DNA and of uracil in RNA.

(B) IMPORTANCE IN REPLICATION, TRANSCRIPTION, TRANSLATION AND DNA HYBRIDISATION TECHNIQUE:-
- Complementary base pairing is very important in the conservation of the base sequence of DNA. -This is because adenine always pairs up with thymine and guanine always pairs up with cytosine.
- In DNA replication this complementary base pairing allows the two DNA molecules to be identical to each other as they have the same base sequence.
- The new strands formed are complementary to their template strands but also identical to the other template. Therefore, complementary base pairing has a big role in the conservation of the base sequence of DNA.

The processes of transcription and DNA replication are fundamental to the metabolism of cells. Describe the major stages of each of these two processes .Although very different in terms of biochemistry they do have organizational features in common. In your answer draw attention to some of these. Note Detail and comprehensive is explantation is required.

For each of the following sequences, state which process, DNA replication, transcription, RNA processing, or translation, is affected most directlyby deleting the sequence below. You should chose only one process for each sequence. (Section 15.4) a. ori site b. 3' splice site c. poly(A) tail d. terminator e. start codon f. –10 consensus seq g. Shine-Dalgarno

Which of the following is most accurate about DNA replication and transcription/translation (central dogma)? Select one: a. DNA replication and transcription/translation produce the same molecules. b. DNA replication occurs in some cells, while transcription/translation occurs in virtually all cells. c. The same enzyme is responsible for DNA replication and transcription/translation. d. DNA replication occurs in virtually all cells, while transcription/translation occurs in some cells. e. DNA replication occurs in somatic cells while transcription/translation occurs only in gametes.
