If the initiating codon of a mRNA became mutated, what would the effect be on the transcript?
faltersainse [42]

Answer:

Translation will not occur.

Explanation:

The start codon is responsible for the initiation of translation in both prokaryotes and eukaryotes. AUG is the start codon in both which code for methionine in eukaryotes and formyl methionine and prokaryotes.

Therefore if the starts codon becomes mutated than the tRNA would not able to recognize the initiation codon and no methionine would be added as the first amino acid so the translation process might not start and no protein forms. Then the ribosome scans further for the next start codon to start translation.

Sam’s teacher is trying to model the day/night cycle on Earth. One student holds a large yellow ball to represent the Sun. Anoth
Orlov [11]
Hello!

So, day and night are caused because the earth makes a full rotation on its axis once every 24 hours.

That way, have of Earth is facing the sun (it is morning on that side) and the other half isn't (which is why it is nighttime over there).

For example, if it's nighttime in Canada and America, it's morning in Pakistan and India. This is because Pakistan and India are facing the sun whilst Canada and America are not.

A N S W E R:

The balls should be moved so that half the Earth is facing the sun and the other half is not. This would be 24 hours. As for the sun, it is a gas, not a solid, so it doesn't rotate like one. However, that does not mean that it is not rotating to some extent.

Levene made which contribution to our understanding of DNA structure? a. He determined that the nucleus contains DNA. b. He dete
Stels [109]

Answer:

The correct answer is  b. He determined that DNA contains four nitrogenous bases.

Explanation:

Levene was an American biochemist who studied the structure of DNA in the early 1900s and in 1920 he found that DNA consists of four nitrogenous bases that are Adenine, Guanine, Thymine, Cytosine.

He also found deoxyribose sugar and phosphate group and said that nucleotide is the basic unit of DNA which contains a ribose sugar with attached nitrogenous base and phosphate group.

He also concludes that an equal amount of adenine, guanine, thymine, and cytosine makes the DNA which is now known as tetranucleotide hypothesis. So the correct answer is b. He determined that DNA contains four nitrogenous bases.
