What is the most abundant protein on Earth?
Rubisco is considered the most abundant protein and enzyme on Earth, with an estimated global mass of about 0.7 gigatonnes. The ranking remains a well-supported claim rather than a complete census.

What is the fastest enzyme?
Catalase is the fastest enzyme by maximum turnover number. One catalase molecule can decompose an estimated 16 million to 44 million hydrogen peroxide molecules per second.

How long does it take to develop a vaccine?
A successful new vaccine usually takes 10 to 15 years to develop. See how research, clinical trials, FDA review, cost, and the COVID-19, polio, mumps, MMR, and Ebola timelines compare.
Genetics · 3 min
How many nucleosomes are in a human cell?
A typical diploid human cell contains about 30 million nucleosomes. See how that estimate is calculated and why a nucleosome can be described as containing 146, 166, or about 200 base pairs.
Proteins · 3 min
How many amino acids are in a complete protein?
A complete protein supplies all nine essential amino acids in adequate amounts. An incomplete protein has too little of one or more, but usually still contains all nine.
