Answer:
Ribonucleic acid (RNA) is a nucleic acid present in all living cells that has some structural similarities to DNA.
Step-by-step explanation:
RNA consists of out an extensive variety of features, from translating genetic records into the molecular machines and structures of the cell to regulating the activity of genes at some point of development, cellular differentiation, and changing environments. connected to each sugar is considered one of four bases: adenine (A), uracil (U), cytosine (C), or guanine (G). exceptional kinds of RNA exist in cells: messenger RNA (mRNA), ribosomal RNA (rRNA), and switch RNA (tRNA). similarly, some RNAs are involved in regulating gene expression.
RNA in cells are themselves copies of DNA sequences contained inside the genes of a cell's chromosomes. Genes that are copied—"transcribed"—into the instructions for making individual proteins are often called "coding genes." The genes that produce RNAs used for other functions are therefore called "noncoding RNA" genes.
