Answer:

A baby with Edwards' syndrome has 3 copies of chromosome number 18 instead of 2. This affects the way the baby grows and develops. Having 3 copies of chromosome 18 usually happens by chance, because of a change in the sperm or egg before a baby is conceived.

The following that are functions of the exoskeleton are:

An exoskeleton is an outer skeleton that is present outside the body of some insects and other organisms. The exoskeleton is made up of hard substances like calcium carbonate or chitin protein.

The exoskeleton protects the soft tissues and organs of organisms. They are helpful in saving the organism from predators and other factors of the environment.

The exoskeleton is present in most arthropods. They also help in reducing water loss from the body.

Thus, the functions of the exoskeleton are:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells

Answer:

nucleus, neutron, proton, electron

Explanation:

The list that correctly orders the parts of an atom from heaviest to lightest

in mass is as follows:

nucleus, neutron, proton, electron

The nucleus of an atom is composed of a tightly packed proton and

neutrons.

This makes the nucleus very dense and small. The nucleus are surrounded

by a negatively  charged electron.

The nucleus contribute to most of the weight of an atom.

This makes the nucleus the heaviest.

The neutron  is found in the nucleus of an atom. The neutrons are

electronically neutral.  The neutron are slightly heavier than proton.

Therefore, the neutron is the second heaviest part of an atom.

The proton is found in the nucleus of an atom. They a positively charged.

The proton is the third heaviest.

The electron revolves around the nucleus and are very light. In fact the

nucleus contributes to 99.9 % of the weight of an atom. This shows how

light the electrons are.

Therefore, the order from the heaviest to the lightest is as follows:

The correct answer would be: 3' - CGTATAAC - 5'

Explanation:

DNA molecule is a double-stranded molecule structure that has two distinct nucleotide chains joined together with hydrogen bonds between the nitrogenous bases of each strand. Adenine binds with thymine and cytosine binds with guanine by hydrogen bonds always in complementary strands.

These strands are complementary to one another as they have complementary bases in the complementary strand of one nucleotide chain of DNA. So,

5' - GCATATTG - 3' - DNA nucleotide of one strand

3' - CGTATAAC - 5' complementary strand

Explanation:

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).

The molecules classified as carbohydrates are oligosaccharides, monosaccharides, disaccharides.

Carbs, or carbs, are sugar particles. Alongside proteins and fats, starches are one of three fundamental supplements tracked down in food varieties and beverages.

Your body separates starches into glucose. Glucose, or glucose, is the principal wellspring of energy for your body's phones, tissues, and organs. Glucose can be utilized right away or put away in the liver and muscles for sometime in the future.

There is nobody size-fits-all measure of starches that individuals ought to eat. This sum can differ, contingent upon variables like your age, sex, wellbeing, and whether you are attempting to lose or put on weight. Overall, individuals ought to get 45 to 65% of their calories from carbs consistently.
