Worksheet on dna answer key

DNA is a long molecule consisting of Deoxyribose, Phosphate, and a nitrogenous base. One of each of these components bonded together correctly forms a nucleotide. The bases form weak bonds between the two strands, which worksheet on dna answer key the whole structure together. His Nobel Prize partner, Francis Crick, was playing tennis at the time.

The discovery of DNA was one of the most significant findings in the field of science. Today, deeper insight into the DNA structure has unravelled answers to questions that have been around for eons. The Central dogma explains how the DNA codes for the proteins which proceed in three stages, namely, replication, transcription and translation. It is one of the first processes in gene expression. The genetic information flows from DNA to protein and this flow of information takes place in a sequential process of transcription and translation. The RNA transcript carries the information used to encode a protein. Also Read: RNA structure. The RNA polymerase is the main enzyme involved in transcription. Once it reaches the terminator sequence, the process terminates and the newly synthesised RNA strand is released. Its function is to encode at least one gene. Suppose if gene encodes protein than mRNA is produced by transcription. A protein encoded by the DNA transcription unit may comprise a coding sequence. Compared to DNA replication, transcription has a lower copying fidelity. Also Read: Central Dogma.

The nucleus is a small spherical, dense body in a cell. It is often called the "control center" because it controls all the activities of the cell including cell reproduction, and heredity. How does it do this? Chromosomes, found in the nucleus, are microscopic, threadlike strands composed of the chemical DNA short for deoxyribonucleic acid. In simple terms, DNA controls the production of proteins within the cell. These proteins in turn, form the structural units of cells and control all chemical processes within the cell. Chromosomes are composed of genes.
