Makemake was discovered on March 31, 2005, by a team at the Palomar Observatory, led by Michael E. Brown, [8] and was announced to the public on July 29, 2005. The team had planned to delay announcing their discoveries of the bright objects Makemake and Eris until further observations and calculations were complete, but announced them both on July 29 when the discovery of another large object ...
1931: A theory of protein denaturation is widely attributed to Alfred Mirsky and Linus Pauling, who published their paper in 1936, [75] though it had been independently discovered in 1931 by Hsien Wu, [76] whom some now recognize as the originator of the theory.
S/2015 (136472) 1, unofficially nicknamed MK2 by the discovery team, [2] is the only known moon of the trans-Neptunian dwarf planet Makemake. [1] [4] It is estimated to be 175 km (110 mi) in diameter and has a semi-major axis of at least 21,000 km (13,000 mi) from Makemake. [1]
Titin [5] (/ ˈ t aɪ t ɪ n /; also called connectin) is a protein that in humans is encoded by the TTN gene. [6] [7] The protein, which is over 1 μm in length, [8] functions as a molecular spring that is responsible for the passive elasticity of muscle. It comprises 244 individually folded protein domains connected by unstructured peptide ...
They used frameshift mutations and a process called reversions, to add and delete various numbers of nucleotides. [4] When a nucleotide triplet was added or deleted to the DNA sequence the encoded protein was minimally affected. Thus, they concluded that the genetic code is a triplet code because it did not cause a frameshift in the reading ...
The 2024 Nobel Prize in chemistry has been awarded to a trio of scientists who used artificial intelligence to “crack the code” of almost all known proteins, the “chemical tools of life ...
A representation of the 3D structure of the protein myoglobin showing turquoise α-helices. This protein was the first to have its structure solved by X-ray crystallography. Toward the right-center among the coils, a prosthetic group called a heme group (shown in gray) with a bound oxygen molecule (red).
This amino acid and tRNA complex was later called aminoacyl-tRNA. Hoagland's major contribution to the laboratory was in his work with amino acid activating enzymes. He discovered that certain enzymes were required to activate amino acids so they could associate with tRNA molecules and eventually be incorporated into new protein molecules.
