Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
Answer:
A) AUG GAG GGU
B) N-MET-GLU-GLY-HIS
C) 10 amino acids
D) The stop codon here is UAA, instead of UAG. If a tryptophane residue is added where the stop codon is, the GEN polypeptide would be longer
Explanation:
First we must obtain the the complementary chain or mRNA
A) AUG start codon is complementary to DNA TAC triplet, and GAG is complementary to CTC, and GGU to CCA (running from left to right towards 5'DNA direction (AAGCGGATACCTCCCAGTAGATGCTCCGGGGCTAGTGATTTCGAAC-5)
B) TAC corresponds to Methionine, GAG to Glutamate, GGU to Glycine, and CAU to Histidine
C) UAA is the stop codon, that is complementary where the DNA triplet is ATT. From AUG to UAA, we can have 10 amino acids transcribed
D) If a trp is included where the stop codon is UAA, then the mRNA would be longer with a consequent traduction of a longer GEN polypeptide
Answer: synthesize a pre-rRNA 45S (35S in yeast), which matures and will form the major RNA sections of the ribosome. RNA polymerase II synthesizes precursors of mRNAs and most snRNA and microRNAs. RNA polymerase III synthesizes tRNAs, rRNA 5S and other small RNAs found in the nucleus and cytosol.
Explanation:
Answer:
oxygen
Explanation:
A limiting factor is any condition whose decrease, increase, absence or presence is able to limit/stop population growth. Examples of limiting factors include abiotic conditions (e.g., temperature, water, oxygen, CO2, etc) or biotic conditions (e.g., food, mate, etc). There are many aquatic species that require high levels of oxygen (e.g., fish), thus being it a limiting factor for these species.
All rock on the ocean floor is less than 180 million years old because <span>reverse polarity removed older rock strips magnetized in a different direction. Also,</span> the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
