Explanation:

Human immunodeficiency virus type 1 (HIV-1) enters target cells by first binding to the primary receptor CD4 and then to a coreceptor, generally one of the chemokine receptors CCR5 and CXCR4 (4). CD4 binding induces structural changes in the envelope (Env) glycoprotein that form and expose the coreceptor binding site. There are two main interactions between Env and coreceptor (13, 14, 25, 50, 51): the base of the third variable loop (V3) engages the N terminus of the coreceptor, while the crown of the V3 loop that includes the highly conserved GPGR/Q arch motif binds to the extracellular loops of the coreceptor, with the second extracellular loop of the coreceptor being particularly important (16, 25, 35, 48, 62). Although some HIV-1 strains are able to use a variety of different G protein-coupled receptors to gain entry into CD4+ cell lines, the great majority of these viruses use CCR5 and/or CXCR4 as coreceptors to infect primary cells (3, 4, 10, 23, 47, 66). CCR3, GPR15, APJ, and FPRL-1 are among the most frequently used alternative coreceptors when overexpressed on cell lines (11, 26, 43, 47, 57). Rare cases of HIV-1 strains that are able to use FPRL-1 and GPR1, but not CCR5 or CXCR4, have been reported (57); however, their in vivo relevance remains unknown.

To characterize the biological processes underlying HIV/simian immunodeficiency virus (SIV) transmission, we recently developed an experimental strategy that permits the identification, enumeration, and molecular cloning of transmitted/founder (T/F) viruses (28, 53). This strategy, which employs single-genome amplification (SGA) and direct amplicon sequencing of HIV/SIV RNA or DNA from the plasma or infected cells, makes it possible to infer the nucleotide sequence of the viral strain(s) that initiated productive infection weeks earlier (1, 28, 29, 37, 53, 58, 67). An important prediction of this approach has been that inferred T/F viruses are fully functional and encode all proteins necessary to establish a new infection. Indeed, this prediction has been borne out in numerous studies, which have shown that T/F viral genes as well as full-length genomes are biologically active. Sets of T/F Envs have been shown to mediate efficient virus entry in single-round infection assays, and they invariably use CCR5 as a coreceptor (28, 34). Similarly, T/F infectious molecular clones (IMCs) of HIV-1, SIVmac and SIVagm all produce replication competent virus that grow to high titers in primary CD4+ T cells (22, 38, 54).

MATERIALS AND METHODS

Amplification of the HIV-1 env gene. Serial plasma samples collected from an acutely infected plasma donor, ZP6248, were purchased from ZeptoMetrix. A total of seven plasma samples were collected between 12 February and 9 March 1997, and viral loads (VLs) were determined by the COBAS Amplicor HIV-1 monitor test.

Sequence analysis. All SGA amplicons were sequenced directly by cycle sequencing and dye terminator methods using an ABI 3730xl genetic analyzer (Applied Biosystems, Foster City, CA). Individual sequences were assembled and edited using the Sequencher program 4.7 (Gene Codes, Ann Arbor, MI). The env sequences were aligned using CLUSTAL W (60), and manual adjustment for optimal alignment was done using MASE (20).

Answer:

After this, rRNA creates bonds between amino acids to make proteins.

Some important points to know:

rRNA (Ribosomal RNA) is used in the synthesis of proteins.

Amino acids are the building blocks of proteins which means that proteins are made up of amino acids.

When amino acids are joined together, they form proteins.

The bond between two or more amino acids when bonded is called "peptide bond".

Answer:

Meiosis end ups with half the no. of chromosomes..

Answer:

Meosis

Explanation:

Meosis 1 ends with 2 diploid cells that end up dividing again into 4 haploid cells.  Thus, the end result of meosis is 4 haploid cells with 23 chromosomes each.

Answer:

It decreases capacity for other species

Explanation:

As humans clear and develop more and more land, the animals that live in the cleared land lose their homes, so they have nowhere to live. This decreases the animals carrying capacity while increasing humans carrying capacity.

Answer:

2 ATP are created in Kreb cycle

Answer:

The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell. ... Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse.

Answer:

A.) Because bacteria only need half the DNA to survive and they are the only ones that do meiosis.

Floods Cause Sedimentation and Erosion riverbanks and forcing them to collapse, for instance, floodwater also can change the terrain. Floodwater suspends silt within the water as it drags debris from the eroding banks, which may deteriorate the water's quality and cause toxic algae blooms.

Explanation:

Answer:

Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.

I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

Answer:

The type of mutation that occurs when one nucleotide in the DNA strand is replaced by another, but the change results in  the same amino acid to be placed next in the protein is a silent mutation.

Explanation:

Silent mutations are molecular mutations where, despite a change in one of the DNA nucleotides, this change has no impact on the amino acid sequence that a synthesized protein will have.

An example of a silent mutation is the change in a DNA sequence TTC where a thymine replaces the cytosine, obtaining the TTT sequence:

                  Normal     With mutation

DNA              TTC            TTT

mRNA           AAG           AAA

Amino Acid   Lys             Lys

There was a nucleotide change in the DNA, but the encoded amino acid was the same, which is a silent mutation that does not affect the amino acid sequence of a protein, its structure or function.

Answer:

a. True

Explanation:

AZT is an abbreviation for azidothymidine and it is the first effective drug against the human immunodeficiency virus (HIV). Thus, azidothymidine is considered to be the first anti-retroviral drug used for the prevention and treatment of the human immunodeficiency virus (HIV).

AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.

Basically, the shape and composition of the reverse transcriptase plays a significant role in the interaction. Therefore, this anti-retroviral drug known as AZT may not work effectively if the shape and composition of the reverse transcriptase changes.

Furthermore, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.

Hence, the human immunodeficiency virus (HIV) possesses a high error rate.

Answer:

Inputs are: Glucose

Output are; carbon dioxide, ATP and heat

Explanation:

Cellular respiration is the metabolic process by which cells of living organisms breakdown glucose molecules to release energy (ATP). Cellular respiration, which is a must for every living organism uses oxygen (aerobic) to break down glucose (C6H12O6) into carbon dioxide (CO2) and water (H2O).

Based on the question asked, the inputs of cellular respiration are GLUCOSE AND OXYGEN while the outputs are CO2, H2O, ATP and HEAT give out. The general chemical equation is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
