Answer: The answer is sample 1 if I’m not mistaken
Explanation:
Because it is :) but yeah...
sample 1 mutation will cause translation to stop. nonsense mutation can cause the termination of translation
What is mutation ?Mutations are defined as the change in the nucleotide sequence of genetic material due to different process such as substitution, deletion or insertion of the nucleotides leading to changed or faulty protein.
The type of mutations leads to the early and delayed termination of the transcription of a gene, mutation of a single nucleotide leads to termination of transcription otherwise called as nonsense mutation.
If a mutation shows no effect on the protein, known as the silent mutation.

What do you mean by cell division?Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

Deletion of a DNA base from a gene affects an organism by—
Causing future gametes to have additional chromosomes
Changing the sequence of amino acids in a protein
Causing chromosome fragments to form long chains
Changing the structure of ribose sugar in nucleic acids
Answer:
Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.
Explanation:
A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:
Transcription of the mRNA, which will have the sequence of altered bases. During translation, the mRNA codons will encode at least one different amino acid. The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.In summary, the deletion of a base in the DNA will affect the protein to be synthesized by changing the amino acid sequence of its structure.
The other options are not possible, because the deletion of a base in the DNA of a gene
Does not influence the number of chromosomes that the gametes will have.
It does not produce long chains in the chromosomes.
It does not affect the ribose structure of the nucleic acids.
Deletion of a DNA base from a gene affects an organism by :
B) Changing the sequence of amino acids in a protein.
DNADeletion of a DNA base from a gene affects an organism by the changing the sequence of amino acids in a protein.
A DNA part shapes a quality, with a particular arrangement of nitrogenous bases, which decides the blend of a particular protein. When a erasure of a base happens in such a quality.

1 .Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge.
2.Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge.
... [All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only.]
3.Gel electrophoresis [ pls chck tiz answer!]
4.DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.
5.A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
Why buffer is used in electrophoresis?High-quality buffers are an important part of electrophoresis. They allow a current to be carried through the sample while resisting pH changes in the overall solution.

Each body cell of a chimpanzee contains 48 chromosomes. After mitosis, how many chromosomes are present in each cell?
Answer:
During both mitosis and meiosis, DNA replicates first during S phase of interphase. Each copy (DNA molecule) is called chromatid. Before anaphase they remain together, joined by the centromere in the chromosome.
Part 1: How many chromatids and chromosomes are present at:
(a) anaphase of mitosis: During this phase sister chromatids split. We would have 48 chromosomes in each pole and 48 chromatides.
(b) anaphase I of meiosis: During this phase homologous chromosomes split, being a reductional division. In each pole we will have half the chromosomes we had after DNA replication. This is 24 chromosomes but 48 chromatides (remember they will split during anaphase II).
(c) anaphase II of meiosis: This is an equational division, we will have 24 chromosomes in each pole and 24 chromatides. Each chromatid is considered a chromosome.
(d) G1 prior to mitosis: During this phase DNA has not replicated yet and it is not condensed either. This formed is called chromatin. We will assign one chromatid for each chromosome. This is a somatic cell, so: 48 chromosomes and 48 chromatids.
(e) G2 prior to mitosis: After S phase, we have duplicated all chromosomes. We will assign two chromatids per chromosome: this is 96 chromatides and 48 chromosomes.
(f) G1 prior to meiosis: Before DNA duplication, 48 chromosomes, 48 chromatids.
(g) Prophase of meiosis I: After DNA replication, condensation of the chromatin takes place: 48 chromosomes, 96 chromatids.
Part 2: How many chromatids or chromosomes are present in:
(h) An oogonial cell prior to S phase: This is G1 phase, 48 chromosomes.
(i) A spermatide: This is the male haploid gametid, after meiosis: 24 chromosomes and 24 chromatids.
(j) A primary oocyte arrested prior to ovulation: They are arrested at prophase I of meiosis. This means their DNA is still duplicated and chromatides have not divided yet. 48 chromosomes and 96 chromatids.
(k) A secondary oocyte arrested prior to fertilization: They are halted at metaphase II of meiosis, meaning they have half the chromosomes (24) but chromatids are still together (48).
(l) A second polar body: They suffered the same process as the mature ovum but remained with little cytoplasm. They have 24 chromosomes and 24 chromatids.
(m) A chimpanzee sperm: They have completed both meiosis as well, they have 24 chromosomes and 24 chromatids.
Explanation:
Mitosis is a type of cell division in which the number of chromosomes in the parent cell is similar to the daughter cell. Mitosis occurs in the somatic cells.
The chromosomes present in the Chimpanzee's cell after mitosis are 48 chromosomes.
The mitosis can be explained as:
1. Mitosis is a type of cell division in which the number of chromosomes in the daughter and parent cells are similar.
2. During the DNA replication process, the DNA is duplicated and separated into the individual two daughter cells.
Thus, the cells with 48 chromosomes will give rise to daughter cells consisting of 48 chromosomes.

DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.
What is DNA replication?The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.
In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.
Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

Answer:
Glycolosis has a net gain of 2 atp
Explanation:
It produces 4 but you invest 2 to start so its only net gain of 2
You also ge 2 pyruvate and 2 NADH
Two pyruvate molecules, two ATP molecules, and two NADH molecules are the substances produced in the process of glycolysis.
These substances are gained from glucose in order to generate energy which is needed in different activities of the cell. ATP is the molecule which is used by the cell for doing activities which needs energy.
Both pyruvate and NADH molecules are also converted into ATP molecules in the end and used by the cell so we can conclude that in the process of glycolysis, two pyruvate, two ATP, and two NADH molecules are formed.

The trend shows that the Enzyme Pepsin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
Explanation:
You can tell by seeing the enzyme activity compared to the pH range. Enzymes are simply proteins which work around your body so pepsin since it is active in acidic levels (pH 2) is probably an enzyme found in the stomach.
The trend shows that the Enzyme Pep sin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
What are the functions of enzyme pepsin?Pepsin is an endo peptidase that breaks down proteins into smaller peptides. It is produced in the gastric cells of the stomach lining and is one of the main digestive enzymes in the digestive systems.
Pep sin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pep sin as an in active zymogen called pepsinogen.
In the digestive tract pepsin effects only partial degradation of proteins into smaller units called peptides, which then either are absorbed from the intestine into the bloodstream.
