Answer:
Protein X would be ultimately present in the subcellular fraction containing membrane fragments
Explanation:
It is possible to trace the synthesis and transport of a membrane protein by the following steps:
1- The amino acids of the membrane protein are joined together in the ribosome to form a polypeptide chain (in this case, the protein X).
2- A signal sequence of the growing polypeptide produces the binding of the ribosome to the membrane of the endoplasmic reticulum (ER) and the insertion of this polypeptide chain into the ER.
3-The protein is released into a vesicle from the ER to be exported to the Golgi complex.
4- The membrane protein is transported by the Golgi complex to the cell membrane by the formation of a secretory vesicle that fuses with the plasma membrane, thus being finally embedded in the lipid bilayer.
Protein X should be present in the subcellular fraction that comprise of membrane fragments
The fraction that should be measured the protein X:
Here the synthesis should be traced and the membrane protein transport should be applied by using the following steps:
Here the amino acids of the membrane protein should be connected together so that the polypeptide chain should be created. A signal sequence with respect to the polypeptide should be grown that generated the ribosome binding. Now the protein should be relased into the vesicle. At last, the protein of the membrane should be transported to the cell membrane.Learn more about cell here: https://brainly.com/question/13250146
what is most likely to result when a mutation affects a DNA sequence?
Answer:

Complete question:
Suppose a graduate student is studying a loss-of-function mutation in the mouse gene zigzag. Whereas wild type mice have straight tails, zigzag mutant mice have tails with two sharp kinks, so that the tail looks like the letter Z. To determine how the zigzag phenotype is inherited, he performs the crosses listed in the first column of the table below, using parents from true-breeding lines. Three possible sets of results from these crosses are shown. Determine the mode of inheritance of the zigzag gene that would yield each result set.
Mode of inheritance Options:
cytoplasmic-linked recessive inheritance, maternal effect inheritance, genomic imprinting (paternal allele is inactive), genomic imprinting (maternal allele is inactive), x-linked recessive inheritanceNote: You will find the table in the attached file
Answer:
Set A: X-linked recessive inheritanceSet B: maternal effect inheritanceSet C: genomic imprint (paternal allele is inactive)Explanation:
SET A:
X-linked recessive inheritance: This pattern refers to a recessive mutated allele that expresses the abnormal character and is linked to the X chromosome.
Cross 1: zig zag female x wild type maleParental) Xz Xz x X+Y
F1) Phenotype---> 50% zigzag (all males) ; 50% wild type (all females)
Genotype---> ½ X+ Xz ; ½ Xz Y
Cross 2:Parental) X+ Xz x Xz Y
F1) Phenotype---> From the whole progeny: 25% wild type females ; 25% wild type males ; 25% zigzag females ; 25% zigzag males - 50% wild type animals + 50% zigzag animals
Genotype---> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y
Cross 3: wild type female x zigzag maleParental) X+ X+ x XzY
F1) Phenotype---> 100% wild type animals (50% females + 50% males)
Genotype ---> ½ X+ Xz ; ½ X+ Y
Cross 4:Parentals) X+ Xz x X+Y
F1) Phenotype---> From the whole progeny: 50% wild type females ; 25% wild type males ; 25% zigzag males
Genotype ---> ¼ X+ X+ ; ¼ X+ Xz ; ¼ X+ Y ; ¼ Xz Y
SET B:
Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. The progeny genotype is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. This effect is commonly seen in insects, but it might also occur in mammals and plants. A much known experiment about this effect is the one performed on Limnea sp snail.
Cross 1: zig zag female x wild type maleParental) Xz Xz x X+Y
F1) Phenotype-->100% zigzag animals, due to the female´s phenotype, Xz Xz
Genotype--> ½ X+ Xz ; ½ Xz Y
Cross 2:Parental) Xx Xz x Xz Y
F1) Phenotype-->100% wild type animals, due to the female´s phenotype, Xx Xz
Genotype--> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y
Cross 3: wild type female x zigzag maleParental) X+ X+ x XzY
F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+X+
Genotype --> ½ X+ Xz ; ½ X+ Y
Cross 4:Parentals) X+ Xz x X+Y
F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+ Xz
Genotype---> 100% wild type animals
SET C:
Genomic imprint (Paternal allele inactive): Refers to a pattern that characterizes for epigenetically inheritance and for unequally functional paternal and maternal genomes. Males X chromosomes are inactive or imprinted and have a different function from those females X chromosomes. This is a common pattern in some mammals, insects and angiosperms. The paternal allele can not be expressed which causes an unequal contribution to the progeny phenotype.
Cross 1: zig zag female x wild type maleParental) Xz Xz x X+Y
F1) Phenotype--->100% zigzag animals, because the male´s X chromosome is imprinted or inactive
Genotype--->½ X+ Xz ; ½ Xz Y
Cross 2:Parental) Xx Xz x Xz Y
F1) Phenotype--->50% wild type animals ; 50% zigzag animals. Due to both the female´s chromosomes, Xx Xz
Genotype---> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y
Cross 3: wild type female x zigzag maleParental) X+ X+ x XzY
F1) Phenotype--->100% wild type animals, due to the female´s phenotype, X+X+
Genotype ---> ½ X+ Xz ; ½ X+ Y
Cross 4:Parentals) X+ Xz x X+Y
F1) Phenotype--->50% wild type animals ; 50% zigzag animals

Which answer best explains the difference between protists and bacteria?
A. Bacteria are prokaryotes and protists are eukaryotes
B. Bacteria have a cell membrane while protists do not
C. Bacteria have ribosomes while protists do not
D: bacteria have cytoplasm while protists do not
Answer:
The correct option is A. Bacteria are prokaryotes and protists are eukaryotes
Explanation:
The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.
The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.
Therefore the answer that best explains the difference between both protists and bacteria
Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.
Is better for an ecosystem to have high or low species abundance?
Answer:
There should equilibrium state in the ecosystem in case of number of species, if there will be high species abundance there would be higher rate of competition in between the species also the predation can be easily seen in such ecosystem. On the other hand if the species abundance is low then the competition between the species and predation can not be seen.PLEASE ANSWER ASAP ILL GIVE YOU THE BRAINLIEST AND ALOT OF POINTS
