Molecular basis of organ differentiation depends on the modulation in transcription by-
1 Anticodon
2 RNA polymerase
3 Ribosome
4 Transcription factor
Explanation:
Molecular basis of organ differentiation depends on the modulation in transcription by transcription factor. - A transcription factors is a protein that binds to specific DNA sequences, thereby controlling the rate of transcription of genetic information from DNA to messenger RNA i.e. mRNA. - Transcription factors bind to either enhancer or promoter regions of DNA adjacent to the genes that they regulate. - Anticodon:- An anticodon is a trinucleotide sequence located at one end of a transfer RNA (tRNA) molecule, which is complementary to a corresponding codon in a messenger RNA (mRNA) sequence. - RNA polemerase :- RNA polymerases is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.

The Okazaki fragments in DNA chain growth:-
1 Polymerize in the 5'-to-3' direction and explain 3'- to 5' DNA replication
2 Result in transcription
3 Polymerize in the \(3^{}\)-to-5' direction and forms replication fork
4 Prove semi-conservative nature of DNA replication
Explanation:
Okazaki fragments are shorts, newly synthesized DNA fragments that are formed on the lagging template strand during DNA replication. These fragments polymerize in the \(5^{}\)-to-3' direction and explain 3'-to5' DNA replication. DNA is synthesized from 5 ' to \(3^{}\), thus when copying the 3'to5' strand, replication is continuous. Phosphodiester links form between the \(3^{}\) to \(5^{}\) and nucleotides can be added with the aid of the enzyme DNA polymerase for the continuous leading strand.

c-DNA is formed from m- RNA by which enzyme?
1 Restriction endonuclease
2 Reverse transcriptase
3 DNA polymerase
4 RNA Polymerase
Explanation:
Complementary DNA (C-DNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by revese transcriptase, a DNA polymerase that can use either DNA or RNA as a template. - A restriction enzyme is an enzyme isolated from bacteria that cuts DNA molecules of specific sequences. - DNA polymerase \(\) DNA replication - RNA polymerase \(\) Transcription

Sequence of DNA (non-coding) is known as
1 exon
2 intron
3 cistron
4 none of these
Explanation:
The gene encoding for mRNA has two type of sequences called the introns and the exons. The introns are the intervening sequences and they do not code for a functional polypeptide. The exons are functional sequences because they contain sequences that are translated into the final protein. Cistron- Cistron is the DNA segments that codes for a specific polypeptide in protein synthesis.
