compared to bacteria, eukaryotic transcription is more complex because _____.
Compared to bacteria, eukaryotic transcription is more complex because eukaryotic cells have a distinct nucleus and multiple types of subcellular organelles, whereas bacteria do not.
In eukaryotic cells, the process of transcription occurs in the nucleus, whereas in bacteria it occurs in the cytoplasm. Additionally, eukaryotic cells have a far more complex system of gene regulation, involving multiple levels of control such as chromatin remodeling and post-transcriptional modifications, whereas bacteria typically have simpler mechanisms of regulation.
Furthermore, eukaryotic cells have multiple types of RNA polymerases, each responsible for transcribing different types of genes, and also eukaryotic cells have a more complex process of RNA processing and maturation, including alternative splicing, cap addition, and polyadenylation, which are not present in bacteria.

The site where two original DNA strands separate and active replication occurs is called a. replication folk b. replisome c. primosome d. lagging strand
This active region is known as a replication fork due to its Y-shaped structure. The DNA polymerase is part of a multienzyme combination that synthesises both new daughter strands' DNA at a replication fork.
What is and how does a replication fork operate?A replication fork comprising two single-stranded templates is created when DNA helicases unwind double-stranded DNA before polymerases do. A lone DNA double helix can be duplicated by replication processes to two DNA helices, that are then split into daughter cells during mitosis.
The replication fork is missing.At the point of replication, a replication bubble is created by opening the circular bacteria chromosome's double-stranded DNA. A replication fork, or Y-junction, which divides double-stranded DNA into two single strands, is present at each end of the bubble.

The degree of symmetry in 2D:4D finger length ratios indicate that if a man has asymmetrical 2D:4D finger length ratios, that means he's Iikely attracted to other men.
Having a 2D:4D finger length ratio is a sexually dimorphic characteristic. Men's second digits (index fingers) are typically shorter than their fourth digits (ring fingers). It is believed that smaller, more masculine digit ratios are linked to either higher prenatal testosterone levels, increased androgen sensitivity, or both.
According to research, having a longer ring finger than index finger indicates that a person was exposed to more male hormones while they were in their mother's womb. Finger lengths vary between and between sexes and are related with development that is generally more masculine than feminine.

Answer:
Please read below:
Explanation:
An ecosystem can sometimes repair itself when it is not severely damaged and the environment is not drastically altered.
For example, if a natural disaster such as a wildfire has occurred, the ecosystem may be able to repair itself over time as long as the environment remains relatively stable.
This is because the environment can provide the necessary resources for the species to rebound and for new species to move into the area.

Cells are made up of a variety of components, including a nucleus, cytoplasm, and a cell membrane.
a. Group A had most likely been placed in distilled water. This can be inferred from the diagram, which shows that group A has a larger size than group B. Distilled water is a pure form of water, while other solutions typically contain other substances that may cause the cells to swell. Therefore, group A was more likely to have been placed in distilled water than group B.
b. Soaking the fish in salt water before freezing them would prevent the damage to the cells because the salt water solution would contain electrolytes and osmotically active particles, which would cause the cells to become more turgid and less prone to bursting when cooled. This is due to the increased osmotic pressure, which would cause more water to enter the cells and force them to swell.

C. Glycine - glutamate - lysine - lysine - stop
D. Isoleucine - alanine- proline- serine- stop
Option D. Isoleucine - alanine- proline- serine- stop, is the amino acid chain that will be produced from the mRNA.
The mRNA sequence AUACUUCCUAGUUGA is translated into a three-nucleotide codon, known as a triplet, which codes for a specific amino acid. The sequence AUACUUCCUAGUUGA is read from 5' to 3', starting with the first nucleotide and ending with the last nucleotide.
The codons are then translated into the corresponding amino acids. The codon sequence AUACUUCCUAGUUGA corresponds to the amino acid sequence isoleucine - alanine - proline - serine - stop. Isoleucine is coded for by the codon AUA.
Alanine is coded for by the codon UAC, proline is coded for by the codon UCC, and serine is coded for by the codon UAG. The codon UGA signals a stop codon, which marks the end of the polypeptide chain.

Active immunity develops as a result of the body's own generation of antibodies, whereas passive immunity is a result of antibodies created outside the body and then brought into the body.
Which of the following best describes the differences between active and passive immunity?Both active and passive immunity exists. When our immune system actively defends us against a pathogen, we are said to have active immunity. When we receive immunity from another person, we are able to defend ourselves against a virus. This is a key distinction between the two types of immunity.

6) Relate each rock cycle factor to plate tectonics
7) Underline why plates move around on earths surface
Answer:
2) One way is that Igneous rock could erode and become sediment and deposited and slowly change into sedimentary rock, then get pushed down deep into the crust and changed by heat and pressure into metamorphic rock.
6) All the igneous rocks which are the basis of the rock cycle are formed by plate tectonics. When the igneous rocks get eroded, they turn into sedimentary rocks. The layers of sedimentary rocks are generally recycled by plate tectonics.
7) The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or a tectonic shift.
