WebDNA replication results in two semi-conservative strands of DNA. DNA helicase separates nucleotides by breaking hydrogen bonds. The double strand unwinds and unzips. The new DNA molecule has two newly-made strands. Question 13 30 seconds Q. The diagram below represents a process that occurs in the nucleus of a eukaryotic cell. WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).

DNA replication take place in the ............ phase of cell cycle.
WebDuring transcription the DNA base sequence is transcribed into a complimentary mRNA sequence. A codon table like the one shown below lists the amino acids coded for by particular triads of mRNA bases. A … WebA segment of DNA has undergone a mutation in which one nucleotide has been changed. The original sequence was ACG and the new sequence is ACA. Use the codon table to determine whether or not this mutation will cause a change in the phenotype of the organism. Even though the DNA sequence changed, the sequence still codes for the … WebDuring DNA replication, the leading strand is synthesized continuously, whereas the lagging strand is synthesized as Okazaki fragments. Why is this so? ANSWER: DNA synthesis can take place only in the 5' to 3' direction. DNA polymerases can bind to only one strand at a time. rcd royale homes silang cavite
