During replication of DNA, Okazaki fragments are formed in the direction of :

The sequence of events mentioned below is symbolized by alphabets. Choose the correct answer where the alphabets are matched with the processes.

RNA —(A)—> DNA —(B)—> DNA —(C)—> mRNA —(D)—> Polypeptide

During transcription, RNA polymerase holoenzyme binds to a gene promoter and assumes a saddle-like structure. What is its DNA-binding sequence?

If one strand of DNA has the nitrogenous base sequence as ATCTG, what would be the complementary RNA strand sequence?

If the sequence of one strand of DNA is

5'-ATGCATGCATGCATGCATGCATGCATGC-3' than it complementary strand have sequence as

The sequence of nitrogen bases in a particular region of the noncoding strand of a DNA molecule was found to be CAT GTT TAT CGC.

What would be the sequence of nitrogen bases in the mRNA that is synthesized by the corresponding region of the coding strand in that DNA?

Assertion: UAA codon is a termination codon.
Reason: If in a mRNA, a termination codon is present, the protein synthesis stops abruptly whether the protein synthesis is complete or not.

Assertion: Replication and transcription occur in the nucleus but translation occurs in the cytoplasm.
Reason: mRNA is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.

Transcription is the coping of genetic information form DNA to mRNA and translation is the formation of polypeptide chain according to code to form protein. Which one follows the other?

Number of nitrogenous bases in a Codon is
