Answer:
e. All of the above are False.
Explanation:
A tRNA is a transfer RNA that carries amino acid from the cell pool to the mRNA-ribosome complex. The anticodon sequence of tRNA is complementary to the mRNA codons and bind to the respective amino acids. None of the tRNA has anticodon for stop codons and therefore, as soon as the ribosome reaches stop codon, protein translation terminates.
AUG is the initiation codon for protein synthesis and codes for methionine when present at a site other than the start site. The initiation codon is often preceded by an untranslated sequence, also called leader sequence. The ribosome moves along the mRNA in 5' to 3' direction in a GTP dependent manner to facilitate elongation of the polypeptide chain.
Answer:
A capstone course, also known as capstone unit or a senior thesis or senior seminar serves as the culminating and usually integrative experience of an educational programtion A capstone project plays a vital role in preparing a student for the future course of learning. It gives students a chance to retain whatever they have been learning during their college studies and apply it once they pursue a specific academic profession in the college.
Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
Answer:
The ability of species of living beings to overproduce offspring
Explanation:
Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically.
Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.
