What is proof-reading In DNA synthesis ?

Name the enzyme which can do proof reading during DNA synthesis in bacterial cells.

Read the paragraph and answer the questions given below: With the help of RNA, the genes present in the form of DNA particioate in the functioning of cell and thereby control the structure and functioning of the body. Information about protein synthesis is stored in the DNA and synthesis of appropriate proteins as per synthesized by DNA through rthe RNA. This is called 'Central Dogma'. mRNA is produced as per the sequence of nucleotides on DNA. Only one of the two strands of DNA is used in this process. The seqience of nucleotides in mRNA being produced is always complementary to the DNA strand used for synthesis. Besides, there is uracil in RNA instead of thymine of DNA. This is process of RNA synthesis is called 'transcription'. What is the similarity between mRNA and DNA?

Pre - DNA synthesis phase is :-

Pre - DNA synthesis phase is :-

Select the correct option Direction of RNA Direction of reading of synthesis the template DNA strand

DNA synthesis proceed in

Write a note on DNA synthesis in vitro.

The enzyme DNA polymerase in E.coli is a DNA dependent polymerase and also has the ability to proof-read the DNA strand being synthesised. Explain. Discuss the dual polymerase.

Refer to the given steps of DNA strands (i) Exposure of DNA strands (ii) Synthesis of RNA primer (iii) Activation of deoxyribonucleotides (iv) Chain formatiion (v) Base pairing (vi) Proof reading and DNA repair ltviigt DNA polynerase attaches at Ori site Select the correct sequence of DNA replication.
