1. What do DNA Replication and Cell Division have in common?
2. Define Cell Differentiation in your own words.
3. Why are stem cells consjdered unique?

Answers

Answer:

1: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. This process is called chromosome segregation.

2: Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.

3: Stem cells have unique abilities to self-renew and to recreate functional tissues. Stem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times.

If a strand of DNA has the nitrogen base sequence, GCTAGATGCG, what will be
the sequence of the complementary strand?

Answers

Answer:

CGATCTACGC

Explanation:

The complementary strand of DNA to GCTAGATGCG is CGATCTAGCT.

The nitrogen bases in DNA are complementary to each other. This means that adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).

The strand of DNA GCTAGATGCG has the following sequence of nitrogen bases:

G - guanineC - cytosineT - thymineA - adenineG - guanineA - adenineC - cytosineG - guanine

The complementary strand of DNA will have the following sequence of nitrogen bases:

C - cytosineG - guanineA - adenineT - thymineC - cytosineT - thymineG - guanineC - cytosine

The complementary strand is created by pairing the nitrogen bases in the original strand with their complementary bases. So, the guanine in the original strand pairs with the cytosine in the complementary strand, the cytosine in the original strand pairs with the guanine in the complementary strand, and so on.

Explanation:

Magma come out of volcanoes that cools down and later on hardens up into rocks.

What is Magma?

The existence of magma is essential to comprehending the geology and morphology of the mantle because the majority of the mantle and crust are solid.

Different types of magma form as a result of variations in the mantle's and crust's structural features, pressure, and temperature. Decompression Melting The mainly solid mantle of the Earth moves higher during decompression melting.

Convection causes this hot material to rise to a place with lower pressure.

Therefore, Magma come out of volcanoes that cools down and later on hardens up into rocks.

When we doing Strawberry Extraction, why do we need to remove the air as much as possible before seal the bag?

Answers

to keep it preserved and delicious

Answer:

Why do we need to cool the mixture? DNases or restriction enzymes that destroy DNA are present in the cell's cytoplasm. They are there to protect the cell from invasion by viruses. Once the nuclear membrane is destroyed by the soap, the DNA is now susceptible to the DNases and will quickly be degraded.

Explanation:

When you added the salt and detergent mixture to the smashed strawberries, the detergent helped lyse (pop open) the strawberry cells, releasing the DNA into solution, whereas the salt helped create an environment where the different DNA strands could gather and clump, making it easier for you to see them.

DNA sequences can act as "tape measures of evolution." Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why?
1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.
4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally.

Answers

Answer:

2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.

Explanation:

Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.

Are any change in the sequence of bases in DNA or RNA that can cause by mutagen or can happen spontaneously in the cell

Answers

Answer:

MUTATION

Explanation:

Mutation is a change or alteration in the genetic sequence of a DNA or RNA (nucleic acid) that are induced by a chemical substance called MUTAGEN or by a spontaneous occurrence. Mutation are of different types depending on how it occurs in the cell. A mutation can be deletion (removal), substitution (replacement), insertion (addition) etc.

Based on this question that states that "any change in the sequence of bases in DNA or RNA that can be caused by mutagen or can happen spontaneously in the cell", the process of MUTATION is being described.

Scientists determined that an unknown organisms was a eukaryote and not prokaryote. Which characteristic would have allowed them to make this determination?


Grupo de escolhas da pergunta


A) Nuclear envelope


B) Cell wall


C) DNA


D) Flagella




ASAP

Answers

Answer:

cell wall would have allowed them to make this determination

Scientists would have determined that an unknown organism was a eukaryote and not a prokaryote based on the presence of a nuclear envelope (Option A).

What is a nuclear envelope?

The nuclear envelope is a double-membrane structure that surrounds the nucleus in eukaryotic cells and separates the genetic material (DNA) from the rest of the cytoplasm. Prokaryotes, on the other hand, do not have a distinct nucleus or a nuclear envelope. Instead, their genetic material is dispersed throughout the cytoplasm and is not separated from the rest of the cell

Options B, C, and D (cell wall, DNA, and flagella) could also be used to determine whether an organism is a prokaryote or eukaryote, but the presence of a nuclear envelope is a key characteristic that definitively separates the two types of organisms.
