DNA replication results in two DNA molecules?
True, during DNA replication, the DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical DNA molecules, each containing one original strand and one newly synthesized strand.
Each DNA strand has a backbone that consists of alternating?
sugar-phosphate groups. These groups are linked together by phosphodiester bonds, forming the DNA backbone. The nitrogenous bases are attached to the sugar molecules extending from the backbone.
How does the base pairing rule ensure each copy of DNA is identical to the original?
The base pairing rule ensures that during DNA replication, each base on one strand pairs with its complementary base on the other strand, forming an identical copy. This process maintains the genetic information in the original DNA molecule and results in the production of two identical DNA molecules.
What enzyme attaches nucleotides together by forming phosphodiester bonds between sugar and phosphate molecules during DNA replication is known as?
The enzyme responsible for attaching nucleotides together by forming phosphodiester bonds during DNA replication is DNA polymerase. DNA polymerase catalyzes the addition of nucleotides to the growing DNA strand using a template strand as a guide.
Parental strands of DNA separate serve as a template and produce DNA molecules that have one strand of parental DNA and one strand of new DNA During what?
This process occurs during DNA replication, which takes place in the S phase of the cell cycle. As the parental strands separate, each serves as a template for synthesizing a new complementary strand, resulting in two DNA molecules, each containing one original (parental) strand and one newly synthesized strand. This semi-conservative mechanism ensures that genetic information is accurately passed on to daughter cells.
What makes up the sides of a DNA strand?
A DNA strand is made up of alternating sugar (deoxyribose) and phosphate molecules. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are attached to the sugar molecules, forming the "rungs" of the DNA ladder.
DNA replication results in two DNA molecules?
True, during DNA replication, the DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical DNA molecules, each containing one original strand and one newly synthesized strand.
How DNA replicates?
DNA first unwinds by the polymerase into two strands, then polymerases run over the two strands, replace a new strand on each old strand, forming two new DNA with one new strand and one original strand in each. (The polymerase is the enzyme)
Each DNA strand has a backbone that consists of alternating?
sugar-phosphate groups. These groups are linked together by phosphodiester bonds, forming the DNA backbone. The nitrogenous bases are attached to the sugar molecules extending from the backbone.
The cellular process of creating two new DNA molecules from one original copy is called replication Which statement is the BEST description of this process?
During DNA replication, the double-stranded DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. Enzymes called DNA polymerases add nucleotides to the growing strand in a direction from 5' to 3'. The end result is two identical DNA molecules, each containing one original strand and one newly synthesized strand.
At the end of replication each new DNA molecule is composed of?
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
How does the base pairing rule ensure each copy of DNA is identical to the original?
The base pairing rule ensures that during DNA replication, each base on one strand pairs with its complementary base on the other strand, forming an identical copy. This process maintains the genetic information in the original DNA molecule and results in the production of two identical DNA molecules.
What is the processof DNA polymerases add complementary nucleotides to each strand which results in the formation of two identical DNA molecules?
dna polymerase
What enzyme attaches nucleotides together by forming phosphodiester bonds between sugar and phosphate molecules during DNA replication is known as?
The enzyme responsible for attaching nucleotides together by forming phosphodiester bonds during DNA replication is DNA polymerase. DNA polymerase catalyzes the addition of nucleotides to the growing DNA strand using a template strand as a guide.
What does semiconservative replication refer to?
Semiconservative replication is a process where the DNA double helix unwinds and each strand serves as a template for the synthesis of a new strand. This results in two daughter DNA molecules, each consisting of one original strand and one newly synthesized strand. This process ensures that each daughter DNA molecule retains half of the original DNA material.
What was Watson and cricks hypothesis for DNA replicating?
Watson and Crick proposed that DNA replicates by unwinding the double helix structure, with each strand serving as a template for the creation of a new complementary strand. This process results in two identical DNA molecules, each containing one original strand and one newly synthesized strand.
What is the DNA Replication?
DNA replication is the process in which the hydrogen bonds between the two strands of DNA are broken and then new DNA nucleotides are bonded along each strand according to the base-pairing rule. The result is two identical molecules of DNA.
