Except for green, these pigments absorb all visible light. They absorb more red and blue wavelengths. The plants reflect greenlight, giving them a green appearance.

Chloroplast contains chlorophyll, also known as photosynthetic pigment, which, along with other pigments in the plant cell, plays an important role in the plant's color component.

Plant cells are eukaryotes, but they are not the same as animal cells. The structures that distinguish a plant cell are the cell wall, which serves as a support and filter, a plastid, which contains the plant's color components, and vacuoles.

Green plants are so because of a pigment called chlorophyll. Chlorophyll absorbs light at specific wavelengths in the visible light spectrum.

False. The synthesis of ATP as a result of electron transport system activity is not referred to as substrate-level phosphorylation.

Substrate-level phosphorylation is a kind of cellular respiration in which ATP is produced directly by transferring a phosphate group from a high-energy substrate molecule to ADP. The electron transport system is a component of oxidative phosphorylation, a kind of cellular respiration that utilises energy provided by the electron transport chain to make ATP via the activity of the ATP synthase complex.

The ATP synthase is a mitochondrial enzyme that catalyses the synthesis of ATP from ADP and phosphate, which is driven by a flux of protons across a gradient formed by electron transfer from the proton's chemically positive to negative side.

The function of RNA in providing the initial recipe for protein synthesis. Transmit data for protein synthesis from the nucleus to the ribosomes.

A crucial molecule for the synthesis of protein is RNA. The enzyme DNA dependent RNA polymerase aids in the conversion of DNA into RNA. Transcription is the procedure that creates the r n e.

The RNA is then sent to the ribosome, where translation transforms it into protein. This means that any shapes are the original design for producing proteins. The transcription and transfer of genetic instructions from the nucleus to the cytoplasm, where proteins are created, is one of RNA's most significant functions. RNA also performs structural, regulatory, and catalytic functions.

The substitution of a single base pair in a triplet codon causes nonsense mutations, which result in one of three stop codons (UAG, UAA, and UGA)

As a result, the triplet codon for an amino acid is changed to one that causes mRNA translation to end too soon and causes a truncated protein.

Because stop codons do not encode for an amino acid but rather mark the completion of protein synthesis, they are also known as nonsense codons. So, prematurely introducing a nonsense or stop codon into the DNA sequence results in nonsense mutations. In general, a stop codon—UAA, UAG, or UGA—in the ribosome's A site is a signal to stop protein synthesis. As it assures the production of complete proteins, this procedure is the final crucial step in the translation process.

Frameshift gene mutation. A protein's inability to function is more likely to result from a frameshift mutation than from a point mutation. This modifies the nucleotide bases in codons, changing their base sequence.

Frameshift gene mutation changes the amino acid sequence and the proteins that come after it. Changing the way a DNA sequence is read, for as through an insertion or deletion, can result in a frameshift mutation, a specific kind of genetic modification. A change in the reading frame occurs when one or more nucleotides are added or deleted.

Crossing over occurs at the ends of the chromosomes, not close to the centromeres, where DNA segments can easily break and reattach.

Option 2 is correct

During the pachytene phase of meiosis, when pairs of chromosomes are fully coupled, crossing occurs.  At diplotene, after homologs divide, the locations of trying to cross become visible as cytokinesis, which holds the two homologs of a pair together until segregation during anaphase I.

Genes are exchanged at random between the parents' chromosomes. During the crossing-over process, gametes generate novel gene combinations.

What are the requirements and consequences of crossing over?

1. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA.

2. Crossing over occurs at the ends of chromosomes, rather than near the centromeres, because segments of DNA near the centromeres cannot break and rejoin easily.

Question:-

The electrical activity that occurs when a muscle is stimulated by a nerve is measured by electromyography (EMG). The examination is done to identify any neuromuscular anomalies.

Electromyography (EMG) detects the electrical activity that occurs when a neuron stimulates a muscle. The test is used to identify aberrant neuromuscular function. One or more tiny needles, commonly known as electrodes, are introduced through the skin and into the muscle during the test. An oscilloscope is then used to display the electrical activity that the electrodes picked up (a monitor that displays electrical activity in the form of waves).

In order to hear the activity, an audio amplifier is employed. The electrical activity of muscles during rest, a light contraction, and a strong contraction is measured by EMG. At rest, muscle tissue doesn't typically create any electrical signals. There is a brief period of activity when an electrode is introduced, but there is no signal beyond that.
