Which macromolecule contains genetic information?
Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
What molecule stores hereditary information?
We now know that the DNA carries the hereditary information of the cell (Figure 4-2). In contrast, the protein components of chromosomes function largely to package and control the enormously long DNA molecules so that they fit inside cells and can easily be accessed by them.
Do carbohydrates transmit genetic information?
Carbohydrates have myriad different functions. They are abundant in terrestrial ecosystems, many forms of which we use as food sources. These molecules are also vital parts of macromolecular structures that store and transmit genetic information (i.e., DNA and RNA).
What is genetic information in biology?
Genetic information. The heritable biological information coded in the nucleotide sequences of dna or rna (certain viruses), such as in the chromosomes or in plasmids.
How are carbohydrate metabolism disorders a hereditary disorder?
Carbohydrate metabolism disorders are hereditary metabolic disorders. Hereditary disorders occur when parents pass the defective genes that cause these disorders on to their children. Carbohydrates are sugars. Some sugars are simple, and others are more complex. Sucrose (table sugar) is made of two simpler sugars called glucose and fructose.
How are genes and chromosomes composed of genetic information?
– Genes are composed of DNA. They carry genetic information and transcribe it into mRNA and tRNA. Chromosomes are composed of proteins and do not carry genetic information. Chromosomes take part in cell division during mitosis and meiosis. – Genes are composed of chromosomes complexed with DNA.
How are chromosomes a functional unit of heredity?
Chromosomes are proteins, they take part in gene expression and are the functional units of heredity. Genes take part in the production of proteins through the processes of transcription and translation. They are the functional units of heredity. Chromosomes carry genes and take part in cell division during mitosis and meiosis.
How is the chromosome theory of inheritance based?
– The chromosome theory of inheritance is based on the parallels between Mendel’s model of heredity and the mutations of chromosomes. – The chromosome theory of inheritance is based on the parallels between Mendel’s model of heredity and the behavior of chromosomes during meiosis.
