Answer:

A. They are constantly moving. I think.

Explanation:

Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. Containing both crust and the upper region of the mantle, lithospheric plates are generally considered to be approximately 60 mi (100 km) thick. Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

What is true about translation? Choose ALL that apply.

Licemer1 [7]

In the process of translation, the statement stands correct and applies are as follows:

The ribosome has two sub-units that work together.
Amino acids are joined by peptide bonds.
Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
The order of the amino acids is determined by the mRNA which is transcribed from DNA.

Answer: Options A, B, C, and E

Explanation:

In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.

Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.

Answer:

ATP and dATP

Explanation:

In the R1 subunit of ribonucleotide reductase, molecules that binds the site regulating overall ribonucleotide reductase activity include both ATP and dATP. In addition, binding of ATP can activate ribonucleotide reductase and the binding of dATP deactivates ribonucleotide reductase.

quester [9]

Answer:

Acquired mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
