Which of the following best describes the function of telomerase?
Which of the following best describes the function of telomerase at the telomere? It adds new DNA to the longer strand of the telomere overhang. Telomeres consist of direct repeat sequences. In the absence of telomerase activity, chromosomes are shortened slightly after every round of replication.
What is telomere and its function?
Telomeres are specialized nucleoprotein structures found at the ends of linear chromosomes that guard against aberrant chromosomal rearrangements and prevent the ends of DNA molecules from being recognized by DNA damage-sensing mechanisms.
Which statement best describes the role of DNA polymerase in the diagram?
Which statement best describes the role of DNA polymerase in the diagram? It brings amino acids together to make proteins. It breaks down and recycles worn-out nucleotides. It enables DNA molecules to condense to form chromosomes.
Which of the following best describes the role of DNA?
Which of the following best describes the role of DNA? DNA translates the information in RNA to make proteins.
What is it called when bacteria take in DNA from their environment?
In transformation, a bacterium takes in DNA from its environment, often DNA that’s been shed by other bacteria. If the DNA is in the form of a circular DNA called a plasmid, it can be copied in the receiving cell and passed on to its descendants. Left: plasmid taken up by transformation.
Which of the following best describes the location in eukaryotic cells and role of DNA?
Which of the following best describes the location (in eukaryotic cells) and role of DNA? DNA is located in the nucleus and contains the instructions needed to build an organism.
Which best describes a eukaryotic cell?
Eukaryotic cell is described as a cell that contains a membrane-bound nucleus. Explanation: The “unique feature of Eukaryotic cell” is that it has a nucleus that enveloped by a plasma membrane. It is different from other organism prokaryotes, which do not have membrane bound nucleus.
Can a eukaryotic cell be found in our bodies?
Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
Which best describes the structure of DNA answers com?
Answer. The right answer to the given question is option A) A double helix. It best describes the structure of a DNA molecule.
Which of the following describes the structure of DNA?
DNA is made up of molecules called nucleotides. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs.
Which sugar is found in a DNA molecule?
deoxyribose
Which of the following best describes the structure of DNA quizlet?
Which of the following best describes the structure of DNA? A double helix consisting of two sugar-phosphate backbones with nucleobases oriented towards the interior.
Which of the following best describes the structure of ATP?
Which of the following best describes the structure of ATP? ATP molecules are composed of a ribose sugar, a nitrogen-containing adenine molecule, and three phosphate groups. ATP molecules are composed of a ribose sugar, a nitrogen-containing adenine molecule, and three phosphate groups.
Which of the following describes the function of genes?
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Which best describes how DNA fits inside a cell nucleus quizlet?
Which best describes how DNA fits inside a cell nucleus? DNA folds into stacked layers called chromatin, which then squeeze into the nucleus. DNA is double-stranded, so one strand is inside the nucleus and the other wraps around the nucleus.
Which best describes how DNA fits inside a cell nucleus?
DNA folds into stacked layers called chromatin, which then squeeze into the nucleus. DNA is double-stranded, so one strand is inside the nucleus and the other wraps around the nucleus. DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
Which three structures are found in both prokaryotic and eukaryotic cells?
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
