8 0

Answer:

Reverse translate from amino acids (protein) to RNA then reverse transcribe to DNA. However, its not exact because there are no introns because they got cut out because they didn't code for the protein so you can't get the original strand and also because some amino acids have multiple codons.

1. What element has 81 protons in the nuclei of its atoms?
lakkis [162]
A little trick i learnt: The atomic number reflects how many electrons there are, and there must be an equal charge. therefore, there are the same amount of protons as there are electrons. so if it has 81 protons, we look for number 81 in the periodic table, Thallium

What characteristic of viruses distinguishes them from cells? They lack an independent metabolism. Their traits do not evolve in
Naya [18.7K]

Answer:

The correct answer is "They lack an independent metabolism"

Explanation:

Viruses are usually active/alive in a living environment and become inactive in non-living environment; these is because they rely on the metabolic activities of the invaded living environment/cell. This property is a sharp contrast to normal living cells that are able to metabolize different substances independently using several organelles.

Whats the difference between the process of cell division and the process of mitosis
creativ13 [48]

There are four phases to the cell cycle: G1, where the cell grows; S phase, where DNA is duplicated; G2, where the cell makes final preparations for cell division; and M phase, where the cell enters mitosis. Mitosis, or cell division, is only a small part of the cell cycle

Regulatory proteins typically contain sites that can bind to other proteins or small molecules. Through such binding interaction
nasty-shy [4]

Answer:

Regulatory sites e.g enhancers and silencers

Explanation:

Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.

Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.

Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
