There are 64 codons and 20 amino acids. Which of the following is not true?
Alisiya [41]

Answer: The option that is not true is D) Each amino acid is specified by only one codon.

Codon can be defined as the sequence of three nucleotides ( present in DNA or mRNA) that corresponds to a particular amino acid. It helps in the process of translation as different amino acids ( that are linked to codons) are assembled to give a particular protein according to the sequence of codon.

There are 64 codons and 20 amino acids that make up the proteins present in the living systems. This indicates that several different codons can correspond to the same amino acid.

For instance, amino acid Valine is coded by four codons that is GUC, GUG, GUA, GUU.

Thus, option D) is incorrect.

Can the atmosphere change in its composition? Explain.
In-s [12.5K]

Hello! Allow me to help!

Your question: Can the atmosphere change in its composition?

My answer: Our atmosphere is made up of many different gases. The most common gases are nitrogen, oxygen and argon. But, the exact amount of each gas is always changing.

Why is my answer correct? Good question! Allow me to explain: Tropical deforestation not only has a large impact on the carbon cycle and climate, but also affects the chemistry of the atmosphere. Together with the carbon cycle and weather patterns land use can affect the concentrations of greenhouse gases like methane and ozone.

Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

Changes in atmospheric composition and the rest of the climate system would include temperature, rainfall, and humidity, which would affect the economic importance, geographical distribution, and management of diseases effecting crop production.

Hope this helps! UwU
