DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Similarly, it is asked, what is on chromosome code specific in a cell?
Chromosomes are composed of genes, which is a segment of DNA that codes for a particular protein, which in turn codes for a trait. DNA is called a nucleic acid because it was first found in the nucleus. We now know that DNA is also found in some organelles such as the mitochondria and chloroplasts.
One may also ask, what makes up the rungs of DNA? Structure of DNA In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
Similarly, you may ask, what is important polymer is located in the nucleus?

What is the function of chromosome 13?
Chromosome 13 is the largest acrocentric human chromosome. It carries genes involved in cancer including the breast cancer type 2 (BRCA2) and retinoblastoma (RB1) genes, is frequently rearranged in B-cell chronic lymphocytic leukaemia, and contains the DAOA locus associated with bipolar disorder and schizophrenia.
Who discovered DNA first?
Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.What is the main purpose of transcription?
Overview of transcription Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence.Where are proteins made in the cell?
Explanation: Ribosomes are the sites where proteins are synthesised. The transcription process where the code of the DNA is copied occurs in nucleus but the main process of translating that code to form other protein occurs in ribosomes.What do genes code for?
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.Why is DNA called the blueprint of life?
DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce. DNA does this by controlling protein synthesis. Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms.What is the shape of DNA called?
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.What is the difference between a gene and a chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.Is DNA a polymer?
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.What are the three components of a nucleotide?
There are just 3 components of nucleotide: nitrogenous base, deoxyribose(sugar) and phosphate group. In DNA, complementary nitrogen bases on opposite strands are connected with hydrogen bond. This is how two DNA strands are held together.What are the three parts of a nucleotide?
A nucleotide consists of three things:- A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil).
- A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons.
- One or more phosphate groups.
