Which of the following steps in preparation of a fully mature eukaryotic mRNA occurs within the nucleus?

Biology
1 answer:
kogti [31]3 years ago
7 0

Answer: e. All of the above

Explanation:

The processing of mRNA  to a fully mature eukaryotic mRNA requires addition of a  5' cap (Capping) and 3' poly(A) tail ( polyadenylation) to the ends of the transcript, and removal of any intervening introns by splicing. Once processing is completed, the mRNP, which consists of mRNA and associated  proteins, is ready for export from the nucleus.

seraphim [82]

Answer:

The use of heat to burn foodstuffs

The use of chemical energy to transport organelles through the cytosol

Explanation:

In plant cells, sunlight energy is converted into chemical energy in a process known as photosynthesis which happens in the chloroplast.

During respiration, cells generally metabolize nutrients to produce useful energy in the form of ATP.

<em>Heat is not used to burn foodstuffs in any cell while organelles are not transported through the cytosol in any cell.</em>

A mutation that involves one or a few nucleotides is called
inysia [295]

A mutation that involves one or a few nucleotides is called

a) mutagen

b) inversion

c) point mutation

d) translocation

Answer:

c) point mutation

Explanation:

When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
