Long polymers made of monosaccharides that have been linked through dehydration synthesis constitute a type of macromolecule generally known as polysaccharides.
Polysaccharides are large carbohydrate molecules composed of repeating units of monosaccharides, which are simple sugars such as glucose, fructose, and galactose. Through a process called dehydration synthesis or condensation reaction, monosaccharides can be joined together by forming glycosidic bonds. In this reaction, a molecule of water is removed, allowing the monosaccharides to bond and form longer chains.
Polysaccharides serve various functions in living organisms. They can be used as energy storage molecules or as structural components. For example, glycogen, a polysaccharide found in animals, acts as a storage form of glucose in the liver and muscles. Starch, found in plants, is another energy-storage polysaccharide. Both glycogen and starch are composed of glucose units joined together in long chains.
Other polysaccharides, such as cellulose and chitin, have structural roles. Cellulose is a major component of plant cell walls and provides rigidity and strength. Chitin is found in the exoskeletons of arthropods (e.g., insects and crustaceans) and provides support and protection.

In which of the following ways is DNA replication similar to transcription?
Answer: D. Thymine is used in replication while uracil is used in transcription.
Explanation:
Genetic information is stored in double-helixes of DNA molecules (Doxyribonuclease). In replication, two daughter strands of DNA are copied from the parent strand, while in replication, instructions stored within DNA are copied into a different form, called mRNA or messenger RNA.
Nucleotides are monomers comprising DNA, a nucleic acid that along with RNA, a ribose sugar-containing nucleotide, acts as a storage molecule to encode proteins. 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogen bases are found in nucleotides:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).
Uracil (U) found in RNA
While both contain four nucleotide bases, in RNA, uracil replaces thymine... The DNA nucleotides are involved in replication while RNA nucleotides drive transcription,
transcription is the assembly of an amino acid chain according to the sequence of base triplets in a transfer rna molecule.
The translation is the assembly of an amino acid chain according to the sequence of base triplets in a transfer RNA molecule. Not transcription.
So, the given statement is false.
The process during which small subunits of ribosomes assemble together and shape up in the form of a sandwich-like appearance is called translation.
During this process, they congregate on the mRNA strand and attract the molecule of transfer RNA (tRNA) which is strongly bound to amino acid molecules.
After this, ribosomes translate the sequence of mRNA and convert the info. into a long chain of polypeptides also known as a complex protein structure. It is made up of amino acid units.

any gene located on a sex chromosome group of answer choices is called
A. a sex-linked gene.
B. is called a recessive gene. C. will exhibit codominance.
D. will exhibit pleiotropy.
Any gene located on a sex chromosome group of answer choices is called A. a sex-linked gene.
Sex-linked genes are genes that are found on the sex chromosomes, specifically the X and Y chromosomes. These genes exhibit inheritance patterns that differ between males and females due to the distinct composition of sex chromosomes. In humans, for example, many sex-linked genes are located on the X chromosome.
The inheritance of sex-linked genes follows specific patterns. For males, who have one X and one Y chromosome, a mutation or variant on the X chromosome will be expressed regardless of its dominance or recessiveness. Females, on the other hand, have two X chromosomes, so the presence of a dominant allele on one X chromosome can mask the effect of a recessive allele on the other X chromosome.

Which organelle contains digestive enzymes that break down waste material and debris in the cell? lysosome ribosome mitochondrion chloroplast
Answer:
Lysosomes
Explanation:
Disintegrator bodies, or lysosomes, are spherical organelles with membranous membranes and active hydrolytic (digestive) enzymes. Lysosomes are huge and plentiful in phagocytes, the cells that eliminate invasive germs and cell debris, as one might expect. Nearly all types of biological compounds can be broken down by lysosomal enzymes. They are known as acid hydrolases because they function best in acidic environments. In two crucial ways, the lysosomal membrane has been modified to support lysosomal activities. In order to maintain the acidic pH of the organelle, it first has H+ (proton) "pumps," which are ATPases that collect hydrogen ions from the surrounding cytoplasm. Second, it keeps the harmful lysosomal enzymes (acid hydrolases) while allowing the digestive end products to escape so that the cell may utilise them or excrete them. Thus, lysosomes offer locations within a cell where digestion may happen safely.
Lysosomes serve as the "demolition crew" of a cell by:
metabolizing endocytosed particles, notably poisons, viruses, and bacteriaDegrading worn-out or dysfunctional organelles and stressed or dead cells, a process more formally known as autophagy ("self-eating")carrying out metabolic processes including glycogen release and breakdownreleasing calcium ions into the blood by breaking down boneThe lysosomal membrane is typically relatively stable, but when the cell is harmed, is oxygenated insufficiently, or has an excessive quantity of vitamin A present, it becomes brittle. Autolysis is the process by which lysosomes burst, causing the cell to devour itself.

what occurs in the sexual reproduction phase of the fungus life cycle?
In the sexual reproduction phase of the fungus life cycle, two haploid cells fuse to form a diploid zygote.
Sexual reproduction in fungi involves the fusion of two haploid cells, each with a single set of chromosomes, to form a diploid zygote with two sets of chromosomes. This zygote then undergoes meiosis to produce new haploid cells, which can grow and develop into new fungal individuals. The sexual reproduction phase in fungi is important for genetic recombination and the generation of genetic diversity. The exact details of the sexual reproduction phase can vary among different species of fungi, but it is typically characterized by the formation of specialized reproductive structures, such as fruiting bodies or hyphae, and the release of gametes or spores that can fuse with compatible partners.

Sex chromosomes are those chromosomes in which sex-determining genes reside. Humans have two sex chromosomes, one inherited from the mother and the other from the father. These two chromosomes differ between males and females.
Females have two X chromosomes, while males have one X and one Y chromosome. Match each phenotype description to its corresponding sex chromosome genotype in humans The five phenotypes listed in the question are described below and matched to their respective sex chromosome genotypes.
XX with SRY on X: This is a genetic disorder that causes individuals with a male gender identity to have two X chromosomes and a single X chromosome with the SRY gene. This can cause the development of female genitalia, although a male gender identity is present. XY with SRY deleted: The Y chromosome determines male development. If the SRY gene, which is located on the Y chromosome, is absent or deleted, male development may not occur as expected, and individuals with an XY genotype may develop female characteristics.
XXX: Females have two X chromosomes, so individuals with three X chromosomes are genetically female. However, the presence of additional sex chromosomes can result in abnormal development.
XXY: An extra X chromosome in males, also known as Klinefelter syndrome, can cause infertility, smaller testicles, reduced body hair, and breast enlargement. XYY: Males with two Y chromosomes, or Jacob's syndrome, are taller than average but may experience delayed language development, learning difficulties, and attention deficit hyperactivity disorder (ADHD).
Therefore, the matching of each phenotype description to its corresponding sex chromosome genotype in humans is shown below:
Phenotypically female with some abnormalities and overexpression of X chromosome genes: XXX Phenotypically male with an increase in average stature: XYY Phenotypically male but karyotype indicates the presence of only X chromosomes: XY with SRY deleted Phenotypically male with sterility and hypogonadism: XXY Phenotypically female but karyotype indicates the presence of both sex chromosomes: XX with SRY on X.
