Answer & Explanation:

1) Transcription is the process by which RNA is assembled, base by base, off a DNA template. True. The transcription process forms a piece of RNA that contains the code for making a protein.

2) Observations are date collected with of the senses or tools such as graduated cylinders, balances, rulers, or pH meters. True.

3) Most RNA is single stranded, where DNA is double stranded. True. Although it's not most RNA, but all RNA is single stranded, that's its main characteristic.

4) RNA occurs in the nucleus as well as in the cytoplasm. True. When RNA comes out from the transcription process it travels to the ribosomes where it's decoded and synthesised, therefore, there should be some RNA somewhere around in the Cytoplasm.

5) RNA has the same deoxyribose sugar that occurs in DNA. False. RNA has ribose, that's why it's called RNA, because it's Ribonucleic Acid.

6) Ribonucleic acid (RNA) was discovered before DNA. True. The RNA was first discovered in 1868 as a component of the nucleus, then, DNA was discovered in 1962.

7) Translation is the conversion of the RNA sequence of enzymes into a polypeptide sequence. True. Translation is the process where RNA is decodified to become peptides and assmblied to become a protein.

8) Translation is the construction of an amino acid sequence from a DNA molecule. False. Although translation involves amino acids in some way, it depends on two types of RNA and doesn't involve DNA.

9)Transcription is the making of an RNA molecule off a DNA template. True. the transcription is a process where DNA is a template for the creation of ARN.

The process of __________ generates the oxygen that we breathe and the food that we eat. view available hint(s)for part a photos

Luden [163]

According to the research, the correct option is photosynthesis. The process of photosynthesis generates the oxygen that we breathe and the food that we eat.

<h3>What is photosynthesis?</h3>

It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.

This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.

Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of photosynthesis generates the oxygen that we breathe and the food that we eat.

What two processes must take place in order to go from a gene to a protein?

yanalaym [24]

Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.

During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm. The mRNA interacts with a specialized complex called a ribosome, which "reads" the sequence of mRNA bases. Each sequence of three bases, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time. Protein assembly continues until the ribosome encounters a “stop” codon (a sequence of three bases that does not code for an amino acid).

The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.”

Through the processes of transcription and translation, information from genes is used to make proteins.

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton

-BARSIC- [3]

Answer:

The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".

Explanation:

0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:

A: 3.21% (m/v) NaCl Solution = crenation (higher than 0.9% (m/v) NaCl)

B: 1.65% (m/v) glucose Solution = hemolysis (lower than 5.0% (m/v) glucose)

C: distilled H2O Solution = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)

D: 6.97% (m/v) glucose Solution = crenation (higher than 5.0% (m/v) glucose)

E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)

What are restriction enzymes? what are restriction enzymes? exonucleases that degrade single-stranded dna endonucleases that ran

tangare [24]

Restriction enzymes, also known as restriction endonucleases, are enzymes that cut a DNA molecule at a particular place. They are essential tools for recombinant DNA technology. The enzyme "scans" a DNA molecule, looking for a particular sequence, usually of four to six nucleotides.
