Answer:C) the sequence of nucleotides in the DNA template
Explanation: During protein synthesis, the nucleotide sequence of a DNA molecule is first copied into a nucleotide sequence of an mRNA molecule, and this takes place in the nucleus. The synthesized mRNA is complementary to the DNA. A DNA has four bases: Adenine, Guanine, Cytosine and Thymine while in mRNA Thymine is replaced by Uracil. The mRNA molecule produced from the DNA is transported to the ribosome where protein synthesis takes place. In the ribosome the nucleotide sequence of the mRNA is then read three nucleotides (codon) at a time to code for amino acids. The amino acid sequence of a protein is determined by the nucleotide sequence of an mRNA and its DNA.
Answer: oligotrophic
Explanation:
A newly formed lake is most likely to be oligotrophic. The oligotrophic lake is expected to have high oxygen concentration in water and low organic and inorganic nutrient content. This condition can only support the growth of small number of plants and algae. The overall growth rate of flora and fauna will be low hence, the biodiversity of a region will be low.
Answer:
Number of protons plus the number of neutrons.
Explanation:
Most of an atom's mass is in its nucleus. The nucleus is made up of protons and neutrons.
Answer is A.
Archaea requires neither sunlight for photosynthesis as do plants, nor oxygen. Archaea absorbs CO2, N2, or H2S and gives off methane gas as a waste product the same way humans breathe in oxygen and breathe out carbon dioxide. An example is chemosynthetic bacteria by sea drifts. They use chemical energy to produce vital processes to live.
Answer:
b) transcription and translation occur simultaneously
