Answer:

Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.

The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.

Chromosomes other than sex chromosomes are known as _____.

Tasya [4]

In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 × 2 = 46).

In what way(s) can mRNAs be processed? In what way(s) can mRNAs be processed? By adding caps and tails to the ends of the mRNAs

sergejj [24]

Answer:

<h2>All of the above are ways in which mRNA can be processed.</h2>

Explanation:

DNA is transcribed into pre-mRNA which is further processed into mature mRNA. mRNA be processed by various ways: as at the 5' end of RNA, addition of capping occurs, and at the 3' end, there is addition of large number of adenosine ( approx 200), known as polyadenylation.

RNA splicing is the process of removal of introns and of addition of exons, through which only coding sequences (exons) remain in the mature mRNA and non coding regions(intron) are removed.

Alternative splicing may produced various type of mRNA from a single type of pre- mRNA.
