The basic unit of the nucleic acid DNA is a DNA nucleotide. There are four different DNA nucleotides, each of which has one of four nitrogen bases. Each DNA nucleotide is composed of the sugar deoxyribose, a phosphate group, and one of four nitrogen bases: adenine, thymine, cytosine, and guanine.
What else can I help you with?
What strand of DNA would be produced from from the template strand of DNA shown below?
Ttg ga
What is the enzyme that correctly attaches new nucleotides to the open strand of the DNA called?
The enzyme responsible for attaching new nucleotides to the open strand of DNA is called DNA polymerase. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the growing DNA strand during DNA replication.
What is the definition for molecules?
Molecules are the smallest units of chemical compounds that retain the chemical properties of the compound. They are made up of two or more atoms bonded together. Molecules can be simple, like oxygen (O2), or complex, like DNA.
How does the process of DNA replication involve the numbering of nucleotides?
During DNA replication, nucleotides are numbered based on their position in the DNA strand. The process involves the separation of the DNA double helix into two strands, with each strand serving as a template for the synthesis of a new complementary strand. As new nucleotides are added to the growing strand, they are numbered sequentially to ensure the accurate replication of the genetic information. This numbering helps maintain the integrity and fidelity of the DNA replication process.
DNA is a chemical code called?
Every strand of DNA has a different code made out of atcg
Why the DNA molecule is compared with a twisted ladder?
the whole DNA strand looks like a twisted ladder. the molecules are on the strand.
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.
A restriction enzyme is likely to cut which kind of molecules?
DNA molecules. A strand of DNA molecules can be cut to have blunted ends or jagged ends (sticky ends).
Name the molecules or parts of a nucleotide which join by a hydrogen bond to attach to the double strand of DNA?
(Adenine and Thymine) or (Guanine and Cytosine) are the respective molecules which join by hydrogen bond to attach to the double strand of DNA.
What is the processof DNA polymerases add complementary nucleotides to each strand which results in the formation of two identical DNA molecules?
dna polymerase
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.
When the new bases are attached two new what are formed?
When the new bases are attached,two new DNA molecules are formed.
If an incorrect nucleotide is incorporated into a fanning strand of DNA will this mistake lie transmitted to the next generation of DNA molecules that forms from this strand?
Yes, if an incorrect nucleotide is incorporated into one strand of DNA during replication, it will be present in the daughter strand and can be transmitted to subsequent generations of DNA molecules. This can lead to mutations and potential genetic disorders.
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.
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.
Who discovered DNA was a strand of molecules in a spiral form?
James Watson and Francis Crick.
