All of the following statements are true about tRNA:
a) tRNA carries special sequences known as codons.
b) Each tRNA binds a particular codon.
c) There are four types of tRNA.
What is a tRNA?tRNA, or transfer RNA, is a small RNA molecule that plays a crucial role in the process of protein synthesis in cells. Protein synthesis occurs in the ribosomes, which are the site of translation in cells. During translation, the information stored in the DNA code is used to synthesize proteins.
tRNA plays a key role in this process by acting as a bridge between the information stored in the DNA code and the sequence of amino acids that make up a protein. Each tRNA molecule carries a specific amino acid and is able to "read" a particular sequence of nucleotides, known as a codon, in the RNA molecule produced during transcription. The tRNA molecule brings the corresponding amino acid to the ribosome, where it is added to the growing protein chain.
In this way, tRNA helps to translate the genetic code stored in DNA into the sequence of amino acids that make up proteins. This process is essential for the proper functioning of cells and is vital for the proper development and function of organisms.

Zeke is attempting to learn more about his world. when he encounters a new object, he picks it up and puts it in his mouth. zeke is most likely in which of jean piaget’s stages of cognitive development?
Zeke is trying to learn more about the world around him. He takes a new object and puts it in his mouth whenever he sees it. Zeke is most likely in the sensorimotor stage of jean Piaget's stages of cognitive development.
Sensorimotor stage: Children use their natural abilities of looking, sucking, grasping, and listening during this early stage of development to gain a deeper understanding of the world around them. To put it another way, they learn about the world through their senses and movements. Children gain a deeper understanding of the world around them through trial and error.
Because infants acquire a fundamental understanding of the world around them through their senses and motor skills, Piaget chose to refer to this stage as the "sensorimotor stage." Infants are able to interact and develop an awareness of themselves and their surroundings thanks to the combination of physical abilities that continue to develop like Zeke picking up the objects and putting them in his mouth is his attempt to learn more about his world.

How are proteins made using the information found in the DNA?
The sandwich-like arrangement of ribosomal subunits on the strand of mRNA that occurs during translation allows them to draw in tRNA molecules bound to amino acids (circles). The ribosome transforms the decoded mRNA sequence into a polypeptide, or new protein, into a lengthy chain of amino acids.
Ribosomes are located where?Depending on whether the cell is from a plant, an animal, or a bacterium, ribosomes are usually found attached to the endoplasmic reticulum and the nuclear envelope, as well as freely dispersed throughout the cytoplasm.
For the purpose of protein synthesis, the mRNA is produced in the nucleus and moved to the cytoplasm. In the cytoplasm, mRNA polymers are wrapped with the ribosomal subunits. Proteins are then created by the tRNA. The building of proteins occurs on ribosomes.

For instance, he discovered that the progeny of crosses between purebred pea plants with tall stems and those with short stems all produced long stems. But when he let these kids self-pollinate, around three-fourths of the offspring had tall stems, while roughly one-fourth had short stems.

The haploid number of chromosomes of a plant is 20. the number of chromosomes in root, stem, and leaf cells would be?
The number of chromosomes in root, stem, and leaf cells would be 40.
Chromosomes are thread-like structures made of protein and a single DNA molecule that transport genomic information from cell to cell. Chromosomes are found in the nucleus of cells in plants and animals.
A chromosome is a long DNA molecule that contains all or part of an organism's genetic material. Most chromosomes have very long thin DNA fibers coated with packaging proteins; the most important of these proteins in eukaryotic cells are the histones.
Genetic diversity is greatly influenced by chromosomal recombination during meiosis and subsequent sexual reproduction. If these structures are incorrectly manipulated, as with chromosomal instability and translocation, the cell may undergo mitotic catastrophe.
Normally, this causes the cell to initiate apoptosis, which leads to its own death, but mutations in the cell can impede this process and thus cause cancer progression.

Asexual reproduction is much simpler than sexual reproduction and can occur in many different ways. In some species, such as bacteria, a single parent can divide into two parts, each of which develops into a new organism.
The major difference between asexual and sexual reproduction is that asexual reproduction produces offspring that are genetically identical to the parent, while sexual reproduction produces offspring that are genetically unique. This is because sexual reproduction combines the genetic materials of two parents, while asexual reproduction does not.

The eyes of clams are located over the circumference of the hemispherical shell. Light travels through the retina of a clam's eye, where it is poorly focussed by the cornea, before being reflected from a hemispherical concave mirror along the back of the eye.Clam eyes can detect fluctuations in light levels because they are light-sensitive.

Chromosome is the final organized form of DNA which is present within the nucleus.
Cells enclose their DNA strands all over scaffolding proteins to construct chromatin, a coiled compressed structure inside the nucleus. Chromatin is hence rolled up into higher powers of structure, resulting in the distinctive shape of chromosomes.
The DNA molecule is encapsulated into thread-like structures known as chromosomes in the nucleus of each cell.

The phenotype is affected by mutations 1 and 2 because in the first, the complete protein is altered, and in the second, the new amino acid may cause the protein to have altered or no function.
What is Mutation?
Mutations can happen naturally or as a result of UV rays, congenital conditions, ionic radiations, or specific free radicals.
Even with the point mutation, there is no alteration to the amino acid sequence, hence the protein will not be affected.
In mutation 1, a new nucleotide is added at codon 9, changing the whole sequence of amino acids and codons in the process, mutation frameshift.
Because a new codon was created as a result of the substitution of one nucleotide by another in mutation 2, produced a new amino acid, so Point mutation.
Therefore, in mutation 3, one nucleotide is swapped out for another, and the resulting codon codes the same amino acid as the one before it, so point mutation.
