4 days ago · Deoxyribonucleic Acid (biology/genetics definition): A helical double-stranded nucleic acid that is crucial for containing the genetic information for cell growth, division, and function . Abbreviation: DNA. Variant: desoxyribonucleic acid. Synonyms: deoxyribose nucleic acid; desoxyribose nucleic acid.
Apr 19, 2024 · Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ).

4 days ago · Definition. Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.
Apr 16, 2024 · Because the nucleus houses an organism’s genetic code, which determines the amino acid sequence of proteins critical for day-to-day function, it primarily serves as the information centre of the cell. Information in DNA is transcribed, or copied, into a range of messenger ribonucleic acid ( mRNA) molecules, each of which encodes the ...

Apr 24, 2019 · Definition. An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists.
Apr 19, 2024 · Definition. A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus.
Apr 3, 2024 · gene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi ), genes are contained within the cell nucleus.
