What are Okazaki fragments how are they welded together?
How are they welded together? Okazaki fragments are short segments of DNA synthesized away from the replication fork on a template strand during DNA replication. Many such segments are joined together by the enzyme DNA ligase to make up the lagging strand of newly synthesized DNA.
What enzyme seals the fragments together?
DNA ligase
What is the difference between conservative and Semiconservative?
Conservative. Replication produces one helix made entirely of old DNA and one helix made entirely of new DNA. Semi-conservative. Replication produces two helices that contain one old and one new DNA strand.
Is DNA replication describe as conservative or semi conservative?
DNA replication is a semi-conservative process. Half of the parent DNA molecule is conserved in each of the two daughter DNA molecules.
What is replicated by a semi conservative process quizlet?
The semiconservative replication of DNA means that a newly formed DNA molecule has one new strand and one strand from the original DNA. If replication were a conservative process, the original DNA would have two heacy strands and all newly formed DNA woul dhave light strands.
What is the point of DNA replication quizlet?
The sole purpose of DNA replication is to generate identical DNA molecules, as they are the blueprint that makes life possible.
What is replication in biology quizlet?
DNA replication definition. the process in which one DNA molecule produces two identical DNA molecules, occurs before the cell divides.
What is copied during replication quizlet?
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
What is the point of transcription quizlet?
The purpose of Transcription is to change DNA into MRNA, and the purpose of translation is to produce proteins from mRNA and tRNA.
What describes what forms after DNA replication takes place?
Finally, an enzyme called DNA ligase? seals up the sequence of DNA into two continuous double strands. The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. Following replication the new DNA automatically winds up into a double helix.
