In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
Answers
Answer:
DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

The stage of mitosis where the chromosomes line up
Answers
Answer:
Metaphase
Explanation:
Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.
Answer:
It is metaphase.
Explanation:
In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
Which of the following occurs first in meiosis?
1. Homologous chromosomes line up in the center of the cell.
2. Chromosomes line up in the middle of each cell.
3. Crossing over between segments of homologous chromosomes.
4. Chromosomes are pulled to opposite poles of the cell.
Answers
Answer:
Crossing over between segments of homologous chromosomes.
Explanation:
Crossing over happens during prophase I of meiosis I

We have 13 different clotting factor proteins in our blood. Do you think hemophilia is controlled by one or multiple genes?
Answers
Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern . The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. Basically it's whatever you believe it is.

Answer:
Simple cuboidal epithelial tissue is specialized for diffusion and absorption. The reason our kidneys function the way they do is because of the movement of water and salts in and out of the kidney tubules.Likewise, the cuboidal shape of the cells allows greater surface area for absorption to take place.

You are trying to determine the mode of inheritance for the mutant curly-winged phenotype in Drosophila. You cross pure-bred wild-type flies with pure-bred mutant (curly-winged) flies and notice that all of F1 has curly wings. You make the scientific hypothesis that the curly-winged phenotype is autosomal dominant to the wild-type wing phenotype. a. If your scientific hypothesis is correct, what ratios would you expect to see in your F2 generation?
Answers
Answer:
The correct answer is - In F2 generation we should get a 3:1 ratio of phenotypes. 3 curly dominant, 1 wild type recessive.
Explanation:
In the given case, the cross between pure-bred wild-type flies with pure-bred mutant (curly-winged) flies and it is found that in F1 generation all offsprings are curly wings which means curly wings are dominant over wild-type.
let assume w gene is responsible for wild type and W gene is responsible for the curly wings which is dominant over wild type
W W
w Ww Ww
w Ww Ww
now on self crossing
W w
W Ww Ww
w Ww ww
In f2 generation there are 75% chances of the curly wing and 25% chances of wild type or the ratio of phenotype would be 3:1

Answers
Answer:
allele-specific oligonucleotides (ASOs)
Explanation:
An allele-specific oligonucleotide (ASO) is a piece of synthetic DNA that is short and usually a complementary to the sequence of a target DNA, It is an oligonucleotide of 15–21 nucleotide bases in length.
It acts as a probe in southern blot assay or simpler Dot blot assay to identify the presence of a target.
It is an important research tool in genetic testing, forensics, and Molecular Biology.
The probes can detect a difference of as little as 1 base in the sequence targeted.
