Dna For Kids Learn Definition Structure Functions Facts Published 13 march 2014 size: 78 kb referencing hub media. the genetic code is the cell’s ‘instruction manual’ for producing a protein from an mrna sequence. three base long sections of mrna (codons) are ‘read’ in sequence at the ribosome. each codon corresponds to a particular amino acid, which is added to the growing protein chain. One cell contains all the genetic information necessary to make a human being. when you look at yourself in the mirror, you’re seeing about 10 trillion cells (1 trillion is 1,000,000,000,000 or a million millions). the main purpose of a cell is to organise. each cell has a different set of functions. there are about 200 different cell types.
Genetic Code And Its Properties The Science Notes The central dogma describes the flow of genetic information in the cell from genes to mrna to proteins. genes are used to make mrna by the process of transcription; mrna is used to synthesize proteins by the process of translation. the genetic code is degenerate because 64 triplet codons in mrna specify only 20 amino acids and three nonsense. Dna profiling. dna profiling is the process where a specific dna pattern, called a profile, is obtained from a person or sample of bodily tissue. even though we are all unique, most of our dna is actually identical to other people’s dna. however, specific regions vary highly between people. these regions are called polymorphic. In this activity, students carry out a genetics webquest using resources from the science learning hub or a genetics animation from the learn genetics website. by the end of this activity, students should be able to: explain the key terms dna, gene, chromosome, trait, genotype and phenotype. describe where dna is found in the body. Translation of the mrna template converts nucleotide based genetic information into a protein product. this flow of genetic information in cells from dna to mrna to protein is described by the central dogma (figure 15.1.1 15.1. 1 ), which states that genes specify the sequence of mrnas, which in turn specify the sequence of proteins.

These instructions are stored as a code made up of four chemical bases: adenine (a), guanine (g), cytosine (c) and thymine (t). double stranded rna (dsrna) rna with two complementary strands. double stranded rna forms the genetic material of some viruses and activates the immune system against a viral infection. 1 in 4 students use ixl. for academic help and enrichment. pre k through 12th grade. sign up now. keep exploring. improve your science knowledge with free questions in "genes, proteins, and traits: understanding the genetic code" and thousands of other science skills.
