What determines the nucleotide sequence of the newly synthesised strand during DNA replication?
The nucleotide sequence of the newly synthesized strand during DNA replication is determined by complementary base pairing. Adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). The existing DNA strand serves as a template for the formation of the complementary strand.
The sequence of what encodes DNA information?
The sequence of nucleotide bases (adenine, thymine, guanine, and cytosine) encodes genetic information in DNA. Each sequence of these bases along the DNA strand forms a gene, which carries the instructions for making proteins and other cellular components. The specific order of these bases determines the genetic code that dictates the traits and functions of an organism.
The first step in making a protein is to make a copy of what?
The first step in making a protein is to make a copy of the gene that codes for that protein. This copy, known as messenger RNA (mRNA), is made through a process called transcription, where the DNA sequence of the gene is converted into a complementary RNA sequence.
Does a typical gene consists of regulatory sites in a promoter and the nucleotide sequence that is transcribed?
Yes, a typical gene consists of regulatory sites in a promoter region that determine when and how much the gene is transcribed. The nucleotide sequence that is transcribed is called the coding sequence, which contains the instructions for making a specific protein or RNA molecule. All these elements work together to regulate gene expression.
What enzyme binds to DNA and is responsible for making a transcript RNA of DNA?
RNA polymerase is the enzyme responsible for binding to DNA and synthesizing a complementary RNA strand during transcription.
What is the difference between the helicase enzyme and DNA polymerase enzyme?
Helicase splits the 3' and 5' Okazaki fragments, while the DNA polymerase attaches the "new" 3' nucleotide, with the "old" 5' nucleotide. As well as proofreading, or making sure that the bases are complementary in order to avoid mutations.
Which enzyme is responsible for making a polymer of DNA by adding one nucleotide monomer at a time?
DNA polymerase is the enzyme responsible for adding nucleotide monomers one at a time to the growing DNA strand during replication.
What determines the nucleotide sequence of the newly synthesised strand during DNA replication?
The nucleotide sequence of the newly synthesized strand during DNA replication is determined by complementary base pairing. Adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). The existing DNA strand serves as a template for the formation of the complementary strand.
Due to the strict pairing of nitrogen base pairs in DNA molecules the two strands are said to be what to each other?
Complementary. The base pairs in DNA always follow a specific pairing rule (A with T, and C with G), which means that the sequence of bases on one strand determines the sequence on the other, making them complementary.
In the process of making a protein the purpose of an adaptor is to a copy the sequence of nucletides into a single strand of RNA B?
recognize a particular three-nucleotide codon
Types of pcr and their significance?
there are; 1. RT PCR - helps in making complementary DNA with the help of mRNA. 2.anchored PCR - helps in making the DNA whose sequence is unknown.
The making of RNA based on the sequence of nucleotides in DNA is called?
The making of RNA based on the sequence of nucleotides in DNA is called transcription. During transcription, an enzyme called RNA polymerase binds to a specific region of DNA, called a promoter, and synthesizes a complementary RNA molecule using one of the DNA strands as a template.

The sequence of nucleotide bases (adenine, thymine, guanine, and cytosine) encodes genetic information in DNA. Each sequence of these bases along the DNA strand forms a gene, which carries the instructions for making proteins and other cellular components.

The first step in making a protein is to make a copy of the gene that codes for that protein. This copy, known as messenger RNA (mRNA), is made through a process called transcription, where the DNA sequence of the gene is converted into a complementary RNA sequence.
Why it is important for a cell to copy DNA without making mistake?
It is important for cell to copy DNA without making mistake because the DNA contain genetic code in the form of nucleotide base pair sequence, if those sequence get wrong then the DNA code for wrong gene i.e. there will be a mutation which can be lethal or dangerous.
