Which best compares DNA and RNA with regard to the process of protein production quizlet?

Which best compares DNA and RNA with regard to the process of protein production? DNA transforms from a nucleic acid into a protein, and RNA remains a nucleic acid. RNA leaves the nucleus during the process and DNA remains in the nucleus. RNA leaves the nucleus during the process and DNA remains in the nucleus.

Do white blood cells have DNA?

DNA is present in white blood cells of humans, but not red blood cells which lack nuclei. A dime-sized spot of blood, approximately 50 µl in volume, is enough DNA for a typical VNTR analysis.

Which scientist discovered DNA after experimenting with white blood cells quizlet?

researched white blood cell structure and looked at used bandages in order to find more white blood cells. While looking through bandages, Miescher discovered and isolated nuclein. Today, nuclein is known as DNA (with a few more proteins).

Who first discovered DNA and named it Nuclein?

DNA was discovered in 1869 by Swiss researcher Friedrich Miescher, who was originally trying to study the composition of lymphoid cells (white blood cells). Instead, he isolated a new molecule he called nuclein (DNA with associated proteins) from a cell nucleus.

Who found DNA first?

What did the duo actually discover? Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.

Where did the first DNA come from?

We are reasonably sure now that DNA and DNA replication mechanisms appeared late in early life history, and that DNA originated from RNA in an RNA/protein world.

What was the first DNA?

According to the authors of the study, these results suggest that the earliest DNA molecules could have appeared in parallel with RNA – some 4 billion years ago. This would mean that DNA molecules emerged around 400 million years earlier than previously thought.

How did life first start on Earth?

ATLANTA—A cataclysm may have jump-started life on Earth. A new scenario suggests that some 4.47 billion years ago—a mere 60 million years after Earth took shape and 40 million years after the moon formed—a moon-size object sideswiped Earth and exploded into an orbiting cloud of molten iron and other debris.
