According to the given situation, the mutation needs 2 X chromosomes and only the mother has 2 X chromosomes whereas a father has X and Y chromosomes.
What are the 23 chromosome pairs?Humans have 23 pairs of chromosomes, 22 pairs of numbered chromosomes, and 1 X and Y chromosome (father) and mother have (XX) chromosomes.
Each parent donates one chromosome to each pair so that offspring get half of their chromosomes from their mother and a half from their father.
Thus, the mother is an answer.

Answer:
B. Fewer people are needed to weed because of herbicides.
Explanation:
Herbicides are chemical substances specifically used to control the widespread growth of weeds i.e unwanted plants. Using herbicides has been useful in eradicating the weeds that pose a great threat to agricultural productivity.
Since chemical control (herbicides) has proven to be a faster and effective method, fewer people are needed to involve in the physical control of weeds i.e. weeding. Hence, the use of herbicides has affected agricultural productivity by helping to reduce the amount of laborers.

You are curious about the dynamic instability of microtubules and decide to join a lab that works on microtubule polymerization. The people in the lab help you grow some microtubules using conditions that allow you to watch individual microtubules under a microscope. You can see the microtubules growing and shrinking, as you expect. The professor who runs the lab gets in a new piece of equipment, a laser beam that is very fine and can be used to sever microtubules. She is very excited and wants to sever growing microtubules at their middle, using the laser beam.
a. Do you predict that the newly exposed microtubule plus ends will grow or shrink? Explain your answer.
b. What do you expect would happen to the newly exposed plus ends if you were to grow the microtubules in the presence of an analog of GTP that cannot be hydrolyzed, and you then severed the microtubules in the middle with a laser beam?
Answers
Answer:
Follows are the explanation to the given points:
Explanation:
The polymerization of αβ-tubulin ligands costumes the microtubules. Among rising or reducing processes a microtubule may oscillate. Part of the carbon is a polar framework for two separate ends: a rapidly growing, most ending as well as a slow-growing less end.
In point a:
Severing a mitochondrial membrane throughout the media will create new "plus ends" or "minus ends." when mentioned in the question Then microtube is more prone to growth at most by adding GTP sub-units to some of the most open regions, where β-tubulin is activated. Even so, for some time GTP has also been hydrolyzed, keeping only one cap of the newly created, higher-end GTP-carrier subunits together with the remaining GDP-carrying cylindrical cap.
Consequently, a positive end is developed that consists of GDP subunits. Because the GDP sub-units become less strictly connected than that of the GTP sub-units, they eventually separate from one another. This allows a microtubule to be polymerized which causes the microtubule will shrink. But the newly exposed microtubule and sides will shrink if cut throughout the center.
In point b:
Well if the equivalent of GTP with such a microtubule is separated by laser from a non-hydrolyzable one, the newly exposed plus finish will include GTP carries. This GTP was NOT supplied with both the GDP kinase but would still expand the mitochondrial membrane. The unburned GTP plus microtubule will therefore continue to grow once it is cut in the center. The GTP equivalent is not hydrolyzable.

The two ways in which selective breeding is helpful are that it can produce crops that are resistant to pests and animals that can produce more food; these are options C and D.
What is the importance of selective breeding?Selective breeding produces plants and animals that are genetically modified to have a specific trait, such as animals being modified to produce higher-quality milk and meat or plants being modified to produce pest-resistant foods. This type of breeding and its resultant product are different from the wild type, and generally, these products are made for the commercial purpose of feeding a large population.

please help :( this assignment is due soon...
Answers
Answer:
The mRNA leaves the nucleus and travels to the ribosome where proteins are synthesized
Explanation:
During transcription, a messenger RNA (mRNA) molecule is synthesized from a specific DNA region which is referred to as a gene. Subsequently, the mRNA leaves the cell nucleus through the nuclear pores of the nuclear membrane and travels to the ribosome, where this sequence serves as template to synthesize a protein, in a process known as translation. Within the ribosomes, triplets of consecutive RNA nucleotides called codons bind to complementary RNA nucleotides (called anticodons) of the transfer ribonucleic acids (tRNAs). Each tRNA attaches a specific amino acid that corresponds to its anticodon sequence, which is then added to the nascent polypeptide chain.

In actuality, the DNA sequence of the human genome is NOT random. Some sequences, including some very large sequences, are repeated many times throughout the human genome. Write two ideas you have for how this fact complicates the use of CRISPR gene-editing technology in humans.
Answers
Answer:
repeated DNA sequences decrease the target specificity of the CRISPR-Cas system, and may lead to off-target effects
Explanation:
The CRISPR-Cas system is a versatile and powerful tool for gene editing. This gene-editing tool consists of a single guide RNA (sgRNA) that guides the Cas endonuclease protein to the appropriate genomic locus, where Cas generate a double-strand break in the DNA and thus induces DNA repair either by Non-homologous end joining (NHEJ) or Homologous Recombination (HR) repair pathways. The sgRNA consists of a 17-20 nucleotide sequence which is complementary to the target DNA, this sequence is called crispr RNA (crRNA). The existence of repeated DNA sequences hampers the specificity of the CRISPR-Cas tool because a particular sgRNA is able to guide Cas9 to different genomic loci that have the same (repeated) nucleotide sequence complementary to the crRNA. In consequence, repeated DNA sequences may lead to undesired off-target effects, i.e., unintended cleavage (and therefore unintended mutations) at untargeted genomic sites.
