When can a species develop generic diversity
sweet [91]
Do you mean (Genetic Diversity)?

All living beings have genetic diversity. Some have more than others.


Woody plants, such as trees, tend to have more genetic diversity, on the whole, than vascular plants, such as grasses. ... Part of the diversity is due to the size of each species' geographic range and how far they can move their genetic information, for example through wind pollination or animal seed dispersers.

The mRNA codon for leucine is 5-UUG-3, and the tRNA anticodon is A) 5-UUG-3. B) 5-GUU-3. C) 5-TTC-3. D) 5-AAC-3. E) 5
miv72 [106K]

Answer:

The correct answer is E) 5-CAA-3.

Explanation:

In translation mRNA sequence is read in 3' to 5' direction by ribosome and tRNA contains anticodon sequence i.e in 5' to 3' direction binds to its complementary codons on mRNA and adds specific amino acid in the chain.

In translation and transcription, uracil comes complementary to adenine nucleotide therefore when mRNA codon is 5' UUG 3' then the anticodon must be in opposite direction and complementary so 3' AAC 5' or 5' CAA 3' would be tRNA anticodon. So the correct answer is E.

Why are well-defined reading frames critical in protein synthesis? A. Without a well-defined reading frame, the mRNA would be tr
DochEvi [55]

Answer:

C

Explanation:

During the translation of an mRNA, it is read in a sequence of three nucleotides called codons. Therefore, a single strand of DNA or RNA will have three reading frames.  Only one is biologically relevant and is referred to as the open reading frame because it is translated to the ideal protein. A shift in the reading of the frame can result in a wrong peptide.

These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.
