The Nucleotide Sequence in mRNA is Determined By?

A nucleotide is the basic building block of nucleic acids such as DNA and RNA. It consists of three parts: a sugar molecule (either ribose or deoxyribose), a phosphate group, and a nitrogenous base. The nitrogenous base can be one of four types: adenine (A), guanine (G), cytosine (C), or thymine (T) in DNA, or uracil (U) in RNA.

The nitrogenous base of a nucleotide is what determines its identity and function in the nucleic acid. The specific sequence of nucleotides in a DNA or RNA molecule encodes the genetic information that is essential for the growth, development, and function of all living organisms. The sequence of nucleotides in DNA is the genetic code that is used to create proteins, which are the building blocks of cells.

In summary, nucleotides are the basic building blocks of DNA and RNA, and they are made up of a sugar molecule, a phosphate group, and a nitrogenous base. The specific sequence of nucleotides in DNA and RNA is responsible for encoding genetic information, which is essential for the function and development of living organisms.

What is a mRNA?

mRNA stands for messenger RNA. It is a type of RNA molecule that carries genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm, where it is used as a template to synthesize proteins. mRNA is transcribed from a DNA template during the process of gene expression, which includes the steps of transcription and translation.

The sequence of nucleotides in mRNA is determined by the sequence of nucleotides in DNA, which is transcribed into mRNA. During transcription, RNA polymerase enzyme reads the DNA template and synthesizes a complementary mRNA strand, with adenine (A) pairing with uracil (U) in RNA, and guanine (G) pairing with cytosine (C). Once the mRNA molecule is synthesized, it is transported out of the nucleus and into the cytoplasm, where it binds to ribosomes and serves as a template for protein synthesis.

The sequence of nucleotides in mRNA is a code that specifies the order of amino acids in a protein. The genetic code is composed of three-letter codons, each of which specifies a particular amino acid. There are 64 possible codons, but only 20 amino acids, so some amino acids are specified by multiple codons. The sequence of codons in mRNA determines the sequence of amino acids in a protein, which in turn determines its three-dimensional structure and function.

In summary, mRNA is a type of RNA molecule that carries genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm, where it is used as a template to synthesize proteins. The sequence of nucleotides in mRNA is determined by the sequence of nucleotides in DNA, and it specifies the order of amino acids in a protein.

Question

The nucleotide sequence in mRNA is determined by?

Answer

The answer is Nucleotide sequence in DNA

Explanation

The nucleotide sequence in mRNA is determined by the sequence of nucleotides in DNA. During the process of transcription, the DNA sequence is used as a template to synthesize a complementary mRNA strand, with adenine pairing with uracil (U) in RNA, and guanine pairing with cytosine as in DNA. Thus, the mRNA sequence is a copy of the DNA sequence, with thymine replaced by uracil.
