helix

Perseverance carries on one of its wheels a symbol of Mars rover tracks twisted into the double helix shape of DNA.

This forms a delicate structure that often resembles a helix or rumpled bedsheets.

Once detected, Cas9 hones in on the site and efficiently cuts the double helix strands.

It’s probably unfair, but from my point of view, the others aren’t as exciting as the discovery of the double helix.

After she helped identify the double helix shape of DNA, Franklin analyzed viruses.

These drugs interfere with the double helix zip-unzip-zip-again process of RNA and DNA replication.

This process, known as epigenetics, involves the addition of small chemical tags known as methyl groups to the DNA double helix.

Maazel writes about a soon-to-be Helix hostage, Anne-Janet, who was on “cancer furlough.”

The largest is Helix pomatia (figured on pp. 11 and 12), which often goes by the name of “the edible snail.”

In 1878 he removed to Umatilla county, Oregon, where he took up a homestead and a timber culture near Helix.

He went carelessly too near the still revolving machinery, and his coat-flap was caught and wound into the helix of the pugmill.

There are to be found in this bed of marl several species of helix and voluta.

If the latter is in the form of a helix its magnetic field resembles that of a straight bar magnet.
