What is true about DNA replication?

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Which of the following is not involved in DNA replication?

RNA polymerase transcribes molecules of RNA from DNA sequences during transcription, and is not involved in DNA replication.

Which of the following is not true about DNA?

DNA strand contains pentose – 2 – deoxyribose sugar. Thus, option (C ) is incorrect.

Which one of the following is false for DNA replication?

The statement pertaining to DNA replication that is false is D: Okazaki fragments are synthesized as part of the leading strand.

What is false about the DNA replication origin?

False. DNA replication origins are typically rich in A‐T base pairs, which are held together by only two hydrogen bonds (instead of three for C‐G base pairs), making it easier to separate the strands at these sites. … Primase is needed to initiate DNA replication on both the leading strand and the lagging strand.

Which of the following is not needed in the replication of the leading strand?

The lagging strand requires an RNA primer to initiate DNA synthesis, whereas the leading strand does not require an RNA primer. c. When DNA polymerase reaches a primer from prior DNA synthesis, the primer is removed and replaced with DNA.

What type of replication is DNA replication?

DNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template for the synthesis of a new, complementary strand. This process takes us from one starting molecule to two “daughter” molecules, with each newly formed double helix containing one new and one old strand.

Which statement is not true for the base ratio of DNA?

“Which statement is not true for the base ratio of DNA ?” Base ratio is constant for a given species. Base ratio is variable for different species.

Which statement is true about DNA replication in prokaryotes but not about replication in eukaryotes?

The only true statement is that prokaryotic DNA replication is faster than eukaryotic DNA replication.

What are the 3 types of DNA replication?

There were three models for how organisms might replicate their DNA: semi-conservative, conservative, and dispersive.

What are the 4 steps of DNA replication?

  • Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. …
  • Step 2: Primer Binding. The leading strand is the simplest to replicate. …
  • Step 3: Elongation. …
  • Step 4: Termination.

Which of the following is not involved in the initiation of replication?

Which of the following is not involved in the initiation of replication? Answer a. Ligase is not involved in the initiation of replication.

What is not true for DNA in prokaryotes *?

Genetic material of prokaryotic cells is carried on a single circular of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no envelope membrane, so there is no true nucleus, and prokaryotes lack histone protein but simply a prokaryotic DNA known as a nucleoid.

What are the 7 steps of DNA replication?

The series of events that occur during prokaryotic DNA replication have been explained below.
  • Initiation. …
  • Primer Synthesis. …
  • Leading Strand Synthesis. …
  • Lagging Strand Synthesis. …
  • Primer Removal. …
  • Ligation. …
  • Termination.

Which is not true of a prokaryote cell?

Which statement is not true about prokaryotic cells? They all have a rigid cell wall instead of a plasma membrane. Mitochondria are thought to have evolved from free-living bacteria that were incorporated into eukaryotic cells by endosymbiosis.

Which is not true of prokaryotic cell?

Besides the absence of a nucleus, prokaryotes also lack mitochondria, or any other membrane-bound organelles that characterize the eukaryotic cell, and it was once thought that prokaryotic cellular components within the cytoplasm were unenclosed, except for an outer cell membrane.

What are the three phases in DNA replication quizlet?

What are the three primary steps of DNA replication? 1) Initiation. 2) Elongation. 3) Resolution/Termination.

Which of the following is not directly needed for translation?

DNA is not needed for translation. The job of DNA is to store information in the nucleus and function as the template for…
