how are the new strands of DNA lengthened

Answers

Answer 1

Explanation:

New strands of DNA are lengthened by adding new nucleotides at the replication fork.

Answer 2

These methods primarily involve DNA synthesis techniques, such as polymerase chain reaction (PCR) and DNA sequencing methods. However, it's important to note that scientific advancements may have occurred since my knowledge cutoff, and there could be new techniques or technologies available.

PCR is a widely used technique that allows for the amplification of specific DNA sequences. It involves a series of heating and cooling cycles, which enable the DNA to denature (separate into single strands) and then be replicated using a DNA polymerase enzyme. By repeating this process, multiple copies of the DNA sequence of interest can be generated.

DNA synthesis involves the chemical synthesis of custom DNA sequences in the laboratory. This process typically employs a method called phosphoramidite chemistry. It starts with a DNA template strand and adds nucleotides one by one, using chemical reactions to build the new DNA strand. This method allows for the controlled synthesis of long DNA strands with specific sequences.

Modern DNA sequencing technologies, such as next-generation sequencing (NGS), can indirectly contribute to DNA lengthening. During the sequencing process, DNA strands are often amplified and replicated to generate sufficient material for analysis. This amplification step can result in the lengthening of DNA strands.

Answers

Answer:

The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]

Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.

Pathogens are disease causing organisms in the body. They attack diverse cells, organs, tissues and systems in the body thereby causing them to malfunction (to become diseased).

Antibodies are the body's natural protective mechanism against pathogens.  Antibodies engulf these pathogens and digest them. Then they produce certain chemicals called antitoxins which now destroy the toxins produced by these pathogens in the body.

Also they activate the systems involved in fighting pathogens by punching the cell wall of invading pathogens.

How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars

Answers

Answer:

b

Explanation:

Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.

The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.  

Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:

DNA is the genetic material of the cell  DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formation  

Thus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.
