Human impacts on biomes are best characterized by _______.

The correct answer is: a. Anticodon loop

tRNA or transfer RNA is an important component in protein synthesis (translation). Its role is to carry amino acids to the ribosome and link a matching a codon in an mRNA with the amino acid it codes for.

The anticodon located on the tRNA (anticodon loop) can bind to one or a few specific mRNA codons.

Final answer:

The correct option is c.

The 3' end of a tRNA molecule binds to amino acids during protein synthesis. Specifically, the CCA tail at this 3' end directly binds the amino acids.

Explanation:

The region of a tRNA molecule that binds to amino acids is the 3′ end. tRNA, which stands for transfer RNA, is crucial for protein synthesis in the cell. The amino acids are attached to the 3′ end of the tRNA molecule. While the anticodon loop, codon loop, and the variable loop are all important aspects of the tRNA structure, it's the 3' end, more specifically the CCA tail at this part, that directly binds to the amino acids during translation.

To count the rate of beating. For instance, if the heartbeat is 70 beats per minute and the stroke volume is 70 cm 3, the cardiac output is 70 70 cm 3 per minute, or 4900 cm 3 per minute.

What is the left ventricle?

The heart's left ventricle is the chamber that pumps blood to all the arteries. The left ventricle is the name for the lower left chamber of the heart. The heart's left ventricle serves as its primary pumping chamber. Left ventricular hypertrophy can cause stiffening of the thicker heart wall.

Because the pressure at which this chamber pumps blood is the same as that in all arteries, you can compute beating by measuring the pulse in the radial artery in your wrist. This artery is easier to discover beating because it is closer to the surface.

Therefore, to count the rate of the beating of the left ventricle, cover SV with your finger, and you are left with CO/HR.

Explanation:

James Watson and Francis Crick, along with the help of Rosalind Franklin's X-ray crystallography data, are credited with first identifying the structure of DNA as a double helix.

The identification of the structure of DNA as a double helix is one of the most significant discoveries in the history of biology. In 1953, James Watson and Francis Crick, both scientists at the University of Cambridge, proposed the double helix model for DNA based on their understanding of its molecular properties and the X-ray crystallography data provided by Rosalind Franklin and her colleague Maurice Wilkins.

Rosalind Franklin, a talented biophysicist, used X-ray crystallography to study the molecular structure of DNA fibers. Her X-ray diffraction images, including Photo 51, provided crucial insights into the helical nature of DNA and its dimensions. Although she did not directly contribute to the final model proposed by Watson and Crick, her work was instrumental in guiding their understanding of DNA's structure.

In April 1953, Watson and Crick published their landmark paper in the journal Nature, titled "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid." In this paper, they described the double helix model of DNA, with the two strands forming a twisted ladder-like structure, and the base pairs holding the strands together like rungs on the ladder.

The identification of DNA's structure as a double helix provided a crucial foundation for understanding how genetic information is stored and transmitted in living organisms. This discovery paved the way for advancements in genetics, molecular biology, biotechnology, and other fields, transforming our understanding of life at the molecular level and earning Watson, Crick, and Wilkins the Nobel Prize in Physiology or Medicine in 1962.

Answer:

Friedrich Miecher was the Swiss chemist who first identified DNA in 1860. It was first identified in the nuclein which is found inside nuclei of the human white blood cells. The nuclein was later on named as nucleic acid. The type of nucleic acid was identified as deoxyribonucelic acid.
