Why cell need to do DNA replication?
DNA is genetic material for many organism and these individuals need to reproduce and make new copy of themselves and to make new copies they need a blue print which stored in DNA. DNA contain all information about the cell.
What is replication?2
It is a process by which cell makes new DNA molecule by using another DNA molecule as template.
What is DNA made of ?
DNA stands for Deoxyribonucleic acid. It contains a nitrogen base, deoxyribose sugar and phasphate group.
STEPS OD DNA REPLICATION-
1.Double stranded DNA is unwounded by helicase. - FORMATION OF REPLICATION FORK.
2. Proteins binds to DNA in order to stablise the single strands
3.primer synthesize RNA primer- FORMATION OF PRIMER BINDING
4..DNA polymerase catalyses formation of suagr phospahte bond between neighboring nucleotide
5.hydrogen bonds forms complementary bases.
Thank you. Please give thumbs up!!!!!!!!!!!!!!!!!!!!!!!!

QUESTION 10 Below is a list of proteins required for DNA replication to occur and functions involved in DNA replication. Match each protein to its function. helicase A catalyzes phosphodiester bonds between two DNA fragments in a strand single strand binding proteins (SSBPs) Rremoves RNA primer and replaces it with DNA topoisomerase cholds DNA polymerase in place during strand elongation - primase D. breaks hydrogen bonds between base pairs and opens the double helix DNA polymerase in E. extends a...
D Question 1 (Matching) Match the enzyme/structure with its role in DNA replication. DNA polymerase synthesizes the new strand of RNA primase Choose synthesizes the new strand of DNA synthesizes a short fragment of complementary RNA attach to template DNA strands to prevent hydrogen bonding Uncoils the supercoil of prokaryotic chromosomes connects Okazaki fragments of new lagging strand of DNA unwinds and unzips the double stranded DNA Single stranded binding proteins (SSB's) DNA Ligase [Choose] Helicase [Choose) DNA Gyrase (Choose]...

the grey are the options
Please match each enzyme with the proper function Primase Helicase ✓ Choose catalyzes the formation of phosphodiester bonds between DNA fragments. unwinds supercolled DNA by catalyzing the controlled Cleavage and rejoining of DNA. coats DNA, preventing duplex formation. removes RNA primers and replaces them with DNA nucleotides. breaks hydrogen bonds, unwinding DNA. synthesizes short sequences of RNA required for DNA replication starts DNA synthesis at the end of a primer. Single-stranded binding protein DNA polymerase...
Question 14:
The answers on 14 and 9 are incorrect.
Answer the question 14 and question 9 plz, thanks a lot.
Helicase strand Refer to the above diagrams and match the components of the replisome with the description of their function A Extends an Okazaki fragment Single-stranded binding Holds DNA polymerase in place proteins (SSBPs) during strand extension H Topoisomerase Catalyzes the breaking of hydrogen bonds between base pairs to open Primase - leading strand the double helix D. Catalyzes...
11. Several enzymes and proteins participate in DNA replication. Answer the fill in the blan below bonds unwinds DNA by breaking the a. The enzyme between the nitrogenous bases bind to single-stranded DNA to stabilize it and to prevent it from reannealing to the other DNA strand. makes DNA This enzyme adds nuceotides to the end of a nucleic acid strands; therefore, it makes DNA in the to direction . DNA Polymerase cannot put two nucleotides together, instead, it adds...
unwinds the dna double helix, synthesizes a short complementary
piece of RNA primer, adds complementary nucleotides in 5' to 3'
direction, forms covalent bonds between Okazaki
fragments
