Codons are three-base sequences in mRNA that specify the addition of a single amino acid to the growing protein chain during translation. How do eukaryotic codons and prokaryotic codons compare?

Answers

Answer 1
Answer:

Answer:

There is no difference between Eukaryotic and prokaryotic codons. All 61 codons and 20 amino acids are same. Start codons are also same.
Answer 2
Answer:

Final answer:

The genetic code is essentially universal, with both eukaryotic and prokaryotic organisms using the same mRNA codons to specify the addition of amino acids or the termination of protein synthesis during translation. The start codon is typically AUG, and it also codes for the amino acid methionine. The uniformity of the genetic code across different life forms suggests that all life on Earth shares a common origin.

Explanation:

Codons are three-nucleotide sequences in mRNA that specify the addition of a specific amino acid or the termination of protein synthesis during translation. There are 64 possible mRNA codons comprising of combinations of A, U, G, and C. Out of these, three are stop codons that indicate the termination of protein synthesis. Typically, AUG is the start codon for initiating translation, and it also encodes for the amino acid methionine.

The genetic code, which is the relationship between an mRNA codon and its corresponding amino acid, is essentially universal and alike for both eukaryotic and prokaryotic organisms, implying that all life on Earth shares a common origin. Such a universal genetic code strongly supports the theory of common descent for all life on Earth.

A plant appears to grow away from the sunlight and the roots appear to grow deeply straight down into the ground. This plant is displaying which of the following?a.positive phototropism and positive gravitropism

b.negative phototropism and positive gravitropism

c.negative phototropism and negative gravitropism

Answers

Answer - B
Phototropism is the response of plants towards the source of the light. If they grow in a direction away from the source of the light, they are exhibiting negative phototropism and if they grow towards the source of light, then it is positive phototropism. Similarly, gravitroprism is the plant's response to gravity in the same manner.
The answer is : B. Negative phototropism and positive gravitropism

Grow away from  the sunlight : indicate negative phototropism. If it's positive that it will grow toward the sunlight

Grow deeply straight down into the ground : indicate positive Gravitropism

hope this helps

Scientific research shows that birds are capable of regenerating their hair cells.

Answers

True.

It has been studied in a research study that claims birds have the ability and capability to regenerate their hair cells. This regeneration happens when the hair cells die but come back to its original form despite the damage it might have faced. Further, they can also regrow their hair cells in their ears. 

Answer:

The answer is T

Explanation:

Scientific research does shows that birds are capable of regenerating their hair cells.

Which of the following would cause an error in DNA replication? A. DNA polymerase pairing A with G B. Helicase making a replication fork C. DNA polymerase checking the DNA D. DNA ligase connecting chunks of DNA

Answers

The correct option is A. DNA replication is the process by which two identical copies of DNA are produce from one original, parent DNA. The process occurs in all living organisms and it is the mean through which traits are passed from parents to offspring. A number of mechanisms has been put in place to ensure that base pairs are accurately copied during the process of DNA replication. For instance, pairing adenosine base with guanosine during the replication process will result in an error, which can have very severe consequences, if it is not corrected.
