A certain regulatory gene is involved in controlling the expression of other genes. In studying this regulatory gene, a scientis

t discovers that it encodes for an enzyme that causes histone deacetylase (the removal of acetyl groups from histone tails). Based on this information, how would you predict that this enzyme regulates gene expression?A. It causes tighter packing of the chromatin at the target gene to inhibit translation.B. It causes decompression of the chromatin at the target gene to inhibit translation.C. It activates gene promoters to signal for the biding of RNA polymerase.D. It activates RNA processing by removing introns and splicing exons together.

Answer:

The correct answer is A it causes tighter packing of the chromatin at the target gene to inhibit translation.

Explanation:

Histone deacetylase is one of the most significant enzyme of chromatin remodeling.Histon  deacetylase carry out the opposite function of histone acetyl transferase that is to remove the acetyl group from the epsilon -NH2 group of amino acid lysine.

  The removal of acetyl group result in the compaction of the chromatin at the the target gene to inhibit translation.

What is not a trend evident to plant evolution<br>​
Archy [21]

Answer:

b. spores of two types to spores of one type

Explanation:

Spores of two types to spores of one type is not the trend to plant evolution because first the spores of one type is present in living organisms but with the passage of time evolution occurs that will leads to formation of  spores of two types happen in living organisms. There are types of spores present in plants such as microspores, which produces male gametophytes, and megaspores, which produce female gametophytes while on the other hand, spores of one type is present in plants having asexual reproduction.

Choose a scientific theory and describe the theory.
faltersainse [42]
I’m not 100% sure if this is a scientific theory but I’m going with the big bang theory. The big bang theory is a scientist best guess on how the world came to be. A 2013 map of the background radiation left over from the Big Bang, taken by the ESA's Planck spacecraft, captured the oldest light in the universe. This information helps astronomers determine the age of the universe.
