B.
Both processes have a growth period called interphase, in which a cell replicates its genetic material and organelles in preparation for division. The two cells that result after meiosis I enter meiosis II very quickly, during the brief interphase period, no further DNA replication takes place.
C.
A. True
Answer:
The area around the "Sahara Desert" is slowly changing into a "dry region", "similar to the desert". "Trait encoding" for "short plant structure" to "reduce transport of water" is "most likely to be selected" in the "population of plants growing" in this region.
Please mark me as brainliest :D
The answer is B) stop condons.
Stop codons, UGA, UAA, and UAG, are nucleotide triplets that signal to stop the translation of an mRNA sequence into proteins.
Answer:
- Based on this information you come to the conclusion that you have been able to identify in these cells the structure of <em>microfilaments</em> or <em>actin filaments</em>.
- <em>Oviductus oblatus</em> are indeed eukaryotic cells
Explanation:
In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a <u>polymer of proteinic subunits</u> united by weak, not covalent connections.
The microfilaments are the thinnest of the three structures. They have a <u>diameter of 7 nanometers</u> and are <u>composed of many proteinic monomers</u> united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.
Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.
Actin filaments have directionality which means that their extremes have different structures.
In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why <u>they are often used as molecular markers</u> for different studies.
Photosynthesis and cellular respiration are very different processes, in
that they require completely different products to produce the
necessary chemical reactions. However, they are similar in that they
both result in energy production for the organisms they are part of.
