Vocabulary: DNA, Chromosome, DNA Replication, DNA Translation, DNA Transcription, Nucleotide, Sugar Phosphate group, Nitrogen Bases (cytosine, guanine, thymine, adenine, uracil), Hydrogen Bond, Polymerase Enzyme, Helicase Enzyme, Base Pair, RNA.

DNA Transcription

is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.

RNA

ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

DNA Replication

the process by which a DNA molecule is copied to produce two identical DNA molecules.

DNA

Deoxyribonucleic acid is a molecule that carries the genetic instruction

Enzyme

Idfk

Nitrogen Bases

The thing on side like (a,t,c,g) that connect

Hydrogen Bond

When the two bases connect they create a ???? bond

Nucleotide

a compound consisting of a nucleoside linked to a phosphate group. They form the basic structural unit of nucleic acids such as DNA.

Base Pair

a pair of complementary bases in a double-stranded nucleic acid molecule, consisting of a purine in one strand linked by hydrogen bonds to a pyrimidine in the other.

Chromosome

a threadlike structure found in the nucleus of most cells, carrying genetic information in the form of genes.

Helicase enzyme

aa class of enzymes vital to all living organisms. Their main function is to unpackage an organism's genes.

Polymerase

an enzyme that brings about the formation of a particular polymer, especially DNA or RNA.

Sugar Phosphate Group

forms the backbone for DNA and RNA (DNA having two sugar molecules, and RNA)
