Central dogma of molecular biology - ️️DNA - RNA - Protein a portion of the DNA, a gene, is transcribed to produce a complementary strand of RNA; then the RNA is translated into protein . -The understanding that DNA is used to make RNA and RNA is used to make protein Polymer - ️️A long molecule consisting of many similar or identical monomers linked together. ex nucleic acids (dna rna) Nucleotides KEY CONCEPTS - ️️-Nucleic acids are polymers of nucleotides. A nucleotide consists of a nitrogenous base, a pentose sugar, and one or more phosphate groups. -DNA contains adenine, guanine, cytosine, and thymine deoxyribonucleotides, whereas RNA contains adenine, guanine, cytosine, and uracil ribonucleotides. -DNA is double-stranded and forms a double helix structure that allows for information storage. Prior to dividing , a cell copies all of its DNA using -DNA replication to ensure all new cells have the DNA they need. -DNA Replication involves the formation of a replication fork, addition of RNA primers to create a "handle" for DNA polymerase, synthesis of the new DNA strand by DNA polymerase, and sealing the DNA backbone by DNA ligase. -RNA is single-stranded and is grouped into three types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). All three types of RNA play an important role in the central dogma. two types of nucleic acids - ️️deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)
