A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis)within a sin

gle coding section of DNA. Mistakes can also occur in the transcription of mRNA or the translation of a polypeptide. However these changes are not considered to be mutations because they are not permanent changes to the cell.True / False.

True

Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.

Explanation:

The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of  several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.

Clathrin coated vesicles bud from eukaryotic plasma membrane fragments when adaptor proteins, clathrin and dynamin-GTP are added
KonstantinChe [14]

Answer: Clathrin cages assemble, vesicles form but cannot be pinched of but no disassembly occurs so the vesicles remain coated in clathrin.

Explanation:

Endocytosis is a cellular mechanism that allows the introduction of extracellular material into the cell. Clathrin-coated vesicles act to incorporate different molecules that are recognized by specific proteins located in the clathrin-coated pits. Upon invagination of a portion of the plasma membrane, the material is transported to its final intracellular destination.

<u>Clathrin is a protein that forms the lining of cell membrane microcavities where various receptors are located. Once a particle is recognized by the receptors, invagination of the plasma membrane occurs, which then fuses to form an endocellular vesicle.</u> When vesicle budding occurs, the vesicle is detached from its attachment to the membrane with the help of a GTPase protein called dynamin. Then, the vesicle is freed from clathrin by the action of a type of ATP-ase called Hsp70-ATP and docks to late endosomes that are immediate precursors of lysosomes, fusing the membranes of both. The fission of the clathrin-coated vesicle is controlled by the GTPase dynamin and it has been proposed that dynamin acts by generating the necessary force to strangle the "neck" and cleave the vesicles from the membrane. So they are mainly involved in the cleavage of newly formed vesicles from the membrane of one cell compartment, their orientation, and their fusion with another compartment. Also, without the dynamin, vesicles are not freed from clathrin.

<u>In the absence of dynamin, vesicles are formed but the membrane fusion or pinching off will not occur. Then, invaginated coated pits will be found.</u>

Compare and contrast the life of a star that has a mass the of a star that has a mass similar to our Sun with the life of a star
Vesnalui [34]
Helloyo!


Massive Star

They are typically greater then 8 molar masses. They typically have a quick main sequence phase, a short red supergiant phase and a death of a spectacular Cosmic event: Supernova. From there they can either become Neutron Stars or Black Holes

Medium-Sized Star

They usually have a Normal Main Sequence phase (Billions of years). From there they bevome Red Giants and expell their mass in a planetary nebula. From there they shrink and become white dwarfs first, then black dwarfs.

d. Deciduous trees such as most pines do not lose their leaves/foliage in winter.

Explanation:

Yes, Rachel Carson is the founder of the modern environmental movement as well as author of Silent Spring. She was an American marine biologist, author, and conservationist which started the modern environmental movement in order to save the environment form pollution. Yes, the Deciduous trees such as most pines do not lose their leaves/foliage in winter, they only lose those leaves that are too old. They are considered as evergreen plants.
