Explain why a solar eclipse occurs only during a new moon.
Dennis_Churaev [7]

An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon's shadow happens to fall upon Earth's surface at that time, we see some portion of the Sun's disk covered or 'eclipsed' by the Moon.

Genetic engineering has the potential to correct
pav-90 [236]
Viruses do not have a nucleus, they cannot be recycled because they release their genetic code and that cannot be recovered unless they replicate and the problem with letting them replicate is that they have a likelihood of mutating and becoming something malicious. So by the power of deduction the correct answer is 3

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome. Match the w
schepotkina [342]

The answers;

1. Termination. Out of the 64 codons, UAG, UAA, and UGA are the stop codons that terminate translation when encountered by the ribosome. These three do not code for any amino acid but rather cause the translation complex to dislocate.


2. Translation. In this process, the ribosome ‘reads’ the codon and brings in a t-RNA with an anticodon to the codon. This tRNA carries a specific amino acid (for that codon) and engages in the P-site of the ribosome. The amino acid is taken from the t-RNA and used to elongate the polypeptide chain being formed. Thereafter the empty t-RNA dislocates.


3. Aminoacyl-tRNA synthetase. When a tRNA brings in an amino acid to the initiation complex, it is dislocated when ‘empty’. Aminoacyl-tRNA synthetase then catalyzes the reattachment of another amino acid through a chemical reaction called esterification. The cognate tRNA then become an aminoacyl-tRNA.


4. tRNA . Every tRNA has an amino acid attached to it. The type of amino acid (out of the 22 amino acids) is determined by the anticodon on the tRNA. There are many codons that are amino acids meaning that there are redundant codons that specify for the same amino acid.


5. Initiation. Initiation begins by the formation of an initiation complex. This complex is comprosed by the two subunits of the ribosome, and the mRNA. The complex becomes compelete when a Met-tRNA (a tRNA with a methionine amino acid) engages the P-site and then translation begins.
