This gene flow creates a new species that is different from previous population of organisms
What process facilitates locomotion for the ovum?
Question 6 options:
a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.
b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.
d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
Explanation
Ovulation is a process in which the ovum is released from the ruptured follicle, there it is captured by the fimbriae and taken to the fallopian tubes (where it will be fertilized by sperm) and then it will reach the uterus (the place where the fetus will grow) through the cilia. Additionally, this process is in which the woman is fertile to conceive and occurs around the fourteenth day of the menstrual cycle (which lasts twenty-eight days).

role does helicase play in DNA replication?
A. Helicase breaks the hydrogen bonds and unwinds a section of DNA.
B. Helicase connects the floating nucleotides to the template strands.
C. Helicase checks the base pairs in each new strand of DNA.
D. Helicase bonds together pieces of DNA as new strands form.
Answer:DNA helicases are also called molecular motors. They unwind the DNA with the help of ATP hydrolysis, and thus facilitate the replication and transcription processes. ... Studies have suggested that DNA helicases may play a role in plant DNA recombination, as it is prominent during the meiotic prophase of plants.
Explanation:
Role played by Helicase in DNA Replication is to break down the hydrogen bonds and unwinds a section of DNA.
What is DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
What is DNA Replication?In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
DNA replication occurs in all living organisms acting as the most essential part for biological inheritance and it is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is composed of two linear strands running opposite to each other and twist together to form.
During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.
Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
What is the role of Helicases in DNA Replication?Helicases are enzymes that bind and remodel nucleic acid or nucleic acid protein complexes.
Helicases are of two types- DNA Helicases and RNA Helicases.
Role of Helicases:
- Separate the double stranded DNA into single one to allow copying.
- Initiate synthesis at the origin of unwinding
- Helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells, to break the bonds.
- DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.
- RNA helicases are involved in shaping the form of RNA molecules, during all processes involving RNA, such as transcription, splicing, and translation.

A triplet of bases in a template strand of DNA is GAT. What would be the corresponding codon for mRNA?
СТА
CUA
CTU
CUA (This one is wrong)
I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!
Answer:
CUA
Explanation:
Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.
DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)
RNA has 4 bases: AUGC (RNA lacks the base T so A binds with U instead).
So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.
A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) in a sequence.
Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.
Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
