The right answers are:
A-present in eukaryotic genomes ==> Both exons and introns
B-generally absent from bacterial genomes ==> Introns
C-part of the final mRNA strand ==> Exons
D-code for an amino acid sequence ==> Exons
E-removed from initial mRNA strand prior to translation ==> Introns
F-present in the DNA used as the template for transcription ==> Both exons and introns
In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.
Answer:
Cells have different shapes because they do different things. The shapes of cells have evolved to help them carry out their specific function in the body, so looking at a cell's shape can give clues about what it does. Neurons are cells in the brain and nervous system.
Explanation: Brainlest plz?
Answer:
It will be observed that in the cell that undergoes the division there is a constriction of the membrane and part of the cytosol, with its chromatic poles at the ends and even possibly double genetic load in the center.
Explanation:
In general, these cells are seen with eosin and hematoxycillin, with which, their internal media will be more basophilic, with more violet staining since they have a high protein load in their interior due to the great genetic load.
During cell division, the genetic load increases because the amount of material is doubled to give a daughter cell.
Answer:
Do you mean one organisms offspring or same species?
Answer:
semen/seminal fluid
Explanation:
The "semen" consists of <em>sperm cells</em> and<em> other secretions</em>. These secretions come from the <u>seminal vesicles, prostate gland, testicles, epididymis, bulbourethral and urethral glands.</u>
Once the male is aroused <em>(through sexual action)</em>, the penis gets larger and this causes the release of the <em>semen </em>from the scrotum <em>(regulates the temperature of the testes)</em><em>. </em>Such process is known as "ejaculation." This fluid has a<em> high potential to make a woman give birth.</em>
