How does DNA differ from RNA biology quizlet?

Firstly, DNA is composed of a double strand forming a helix whereas RNA is only composed of one strand. Also the sugar in DNA is deoxyribose whereas in RNA it is ribose. Finally, both DNA and RNA have the bases adenine, guanine and cytosine. However DNA also contains thymine which is replaced by uracil in RNA.

Which of the following is a major difference between RNA and DNA mastering biology?

Which of these is a difference between a DNA and an RNA molecule? DNA is usually double-stranded, whereas RNA is usually single-stranded.

Which of these is a difference between DNA and RNA quizlet?

Which of these is a difference between a DNA and an RNA molecule? DNA contains nitrogenous bases, whereas RNA contains phosphate groups.

Which of these is a difference between DNA and RNA?

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

What are three ways RNA differs from DNA?

  • A Ribonucleotide.
  • The 5-Carbon Sugar Ribose.
  • The Four Nitrogenous Bases in RNA: Adenine, Guanine, Cytosine, and Uracil.
  • A Phosphate Group.

How does RNA differ from DNA Quizizz?

RNA contains sucrose while DNA contains glucose. DNA contains deoxyribose while RNA contains ribose. Two other differences between RNA and DNA involve… the fact that one is composed of purines while the other is composed of pyrimidines.

Which of the following is found in RNA but not in DNA?

Answer and Explanation: The nitrogenous base that is found in RNA but not in DNA is c. uracil. Additionally, RNA contains a sugar known as ribose.

What is the function of DNA polymerase III mastering biology?

DNA pol III adds nucleotides to the 3′ end of the leading strand so that it elongates toward the replication fork. -In contrast, the lagging strand is made in segments, each with its own RNA primer. DNA pol III adds nucleotides to the 3′ end of the lagging strand so that it elongates away from the replication fork.

What is the role of DNA polymerase during DNA synthesis mastering biology?

DNA polymerase is the enzyme that catalyzes the addition of a nucleotide onto the 3′ end of a growing DNA strand. DNA polymerase catalyzes the synthesis of the template strand of DNA.

What are four differences between RNA and DNA?

DNA has four nitrogenous bases – Adenine, Guanine, Cytosine and Thyamine. RNA also has four nitrogenous bases, Adenine, Guanine, Cytosine and Uracil.

What are the five differences between DNA and RNA?

What is the product of translation?

Answer and Explanation: The product of translation is protein. The translation is a process in which the genetic information contained in an mRNA is decoded into a specific sequence of amino acids to produce polypeptides or proteins.

Why is it important for a single gene to be able to produce hundreds or thousands of the?

Proteins must be continuously synthesized in the cell, so the instructions coded in genes must be used over and over again. Therefore, a single gene must be able to produce hundreds or thousands of the same RNA molecules for protein synthesis.

Do you NÉE is a nucleic acid polymer composed of which repeating structural unit?

The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base – (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.

What is true about DNA but not RNA?

Explanation: RNA contains uracil, while DNA contains thymine. All of the other statements are true. Note that DNA is usually double-stranded and RNA is usually single-stranded, but both can exist in the opposite configuration under certain conditions.

What bases are found in DNA and RNA?

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine.

Which of these is responsible for catalyzing the formation of an RNA primer mastering biology?

Which of these is responsible for catalyzing the formation of an RNA primer? Primase catalyzes the formation of an RNA primer.

What is the process called that converts the genetic information stored in DNA to an RNA copy?

During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

What catalyzes DNA synthesis?

DNA polymerase is the enzyme which catalyzes DNA synthesis. It is capable of adding nucleotide triphosphates to a chain of DNA.

What is the role of DNA polymerase during DNA synthesis mastering biology quizlet?

What is the role of DNA polymerase during DNA synthesis? DNA polymerase is the enzyme that catalyzes the addition of a nucleotide onto the 3′ end of a growing DNA strand.

How does DNA polymerase work?

DNA polymerase works by sliding along the single strand template of DNA reading its nucleotide bases as it goes along and inserting new complementary nucleotides into the primer so as to make a sequence complementary to the template. DNA polymerase is thought to be able to replicate 749 nucleotides per second.

What is DNA polymerase in DNA replication?

DNA polymerase is responsible for the process of DNA replication, during which a double-stranded DNA molecule is copied into two identical DNA molecules. Scientists have taken advantage of the power of DNA polymerase molecules to copy DNA molecules in test tubes via polymerase chain reaction, also known as PCR.

Is RNA a copy of DNA?

​Transcription Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA.

What is the job of mRNA?

The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.

How is DNA translated into mRNA?

During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).
