Exempel på hur man kan använda HELIX i en mening

• Under this definition, well-known members include carrots, celery, parsley, and Hedera helix (English ivy).
• An alpha helix (or α-helix) is a sequence of amino acids in a protein that are twisted into a coil (a helix).
• They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA.
• Amino acids are bound together to form a triple helix of elongated fibril known as a collagen helix.
• An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix).
• In molecular biology, the collagen triple helix or type-2 helix is the main secondary structure of various types of fibrous collagen, including type I collagen.
• Single-strand breaks are repaired by DNA ligase using the complementary strand of the double helix as a template, with DNA ligase creating the final phosphodiester bond to fully repair the DNA.
• In 1953, he co-authored with Francis Crick the academic paper in Nature proposing the double helix structure of the DNA molecule.
• Pauling also worked on the structures of biological molecules, and showed the importance of the alpha helix and beta sheet in protein secondary structure.
• As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions.
• In her book Who's Who in Classical Mythology, author Adrian Room describes the name's etymology: "we can perhaps see in his name a blend of ceras, 'horn' and helix, 'twisted', or even a link with cyllos, 'crooked'".
• The energy from the redox reaction results in conformational change allowing hydrogen ions to pass through four transmembrane helix channels.
• The road is owned and operated by the New Jersey Turnpike Authority (NJTA) between the New Jersey Turnpike and Route 3, the New Jersey Department of Transportation (NJDOT) between Route 3 and Park Avenue near the Union City–Weehawken border, and by the Port Authority of New York and New Jersey (PANYNJ) east of Park Avenue, including the helix viaduct used to descend the New Jersey Palisades to reach the entrance of the Lincoln Tunnel.
• This 'globin fold' typically consists of eight alpha helices, although some proteins have additional helix extensions at their termini.
• Four are normally to be found on an Ionic capital, eight on Composite capitals and smaller versions (sometimes called helix) on the Corinthian capital.
• A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis.
• ABO blood group system – abscisic acid – absorption spectrum – abyssal zone – acetylcholine – acetyl-CoA – acid – acid precipitation – acoelomate – acrosome – actin – action potential – active site – adaptive radiation – address-message concept – adenosine 5'-triphosphate – adenylyl cyclase – adrenal gland – adrenodoxin – aerobic organism – age structure – agonist – AIDS – albumin – aldehydes – aldosterone – algae – allantois – allele – allometry – allopatric speciation – allosteric binding site – allosteric effector – allosteric enzyme – allosteric site – allozyme – alpha helix – amino acid – aminoacyl tRNA synthetase – amino group – amniocentesis – amniote – amphipathic molecule – anabolism – anaerobic organism – anaerobic respiration – androgen – anemia – aneuploidy – angiosperm – anther – anthrax – antibiotic – antibody – anticodon – antidiuretic hormone – antigen – apical dominance – apical meristem – apolipoprotein – apoplast – apoptosis – aquaporin – Archaea – archegonium – arteriosclerosis – artery – arthritis – ascus – asexual reproduction – atomic number – ATP – ATP synthase – atrioventricular valve – atrium – autoimmune disease – autonomic nervous system – autosome – auxin – axillary bud – axon.
• In semiconservative replication, when the double-stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from the original helix and one newly synthesized.
