Meiosis reduces chromosome number and rearranges genetic information. Explain how reduction and rearrangement are accomplished in meiosis. Include at least 3 ways this happens.

Answers

Answer 1

Answer:

Following are the solution to the given question:

Explanation:

Reduction: Throughout Meiosis I, in mitosis, two pairs pair and separate and transfer towards opposites throughout prometaphase I. Before Metaphase ii they separate the chromosomes during Metaphase II. There's also no gene replication between meiotic division I and meiosis II, and the resultant genomes have lower genetic data (chromatids) than parent organisms.  

Through meiosis, genomes are formed in homologous pairs, in mitosis I and II. The spontaneous arrangement of helices with both the plate is the dependent result. During prometaphase I and II, the genomes divide so each gamete earns one of every chromos form. In Interphase I, tetrad interaction occurs throughout chiasma, contributing to genetic diversity.

How much of the energy (what percentage) of oxidizing Glucose to Pyruvate is captured in Catabolism as NADH ( H ) and ATP?

Answers

Answer:

40 percent.

Explanation:

About 40 percent of energy as ATP is produced due to oxidizing Glucose molecule in the process of respiration while the remaining 60 percent is lost as heat energy which is responsible for the generation of high body temperature. One molecule of glucose produces four molecules of ATP, two molecules of NADH, and two molecules of pyruvate during the first stage of respiration known as glycolysis while in the end of respiration process only ATP, carbondioxide gas and water is produced.

An organism is exposed to a mutagen, such as X-rays or ultraviolet light. What could be the effect of the mutagen on the organism? Select all of the answers that apply.
The mutagen may disrupt gene function to the harm of the organism.
B. The mutagen may change gene function in a way that benefits the organism.
C. The mutagen may change the genetic material of the cell from DNA to proteins.
D. The mutagen may change the binding between codons and anticodons.
E. The mutagen may have little or no observable effect on the organism.

Answers

Answer:

a, b, c, e

Explanation:

- since mutations are random, they could both harm or benefit or have no effect on the organism (depends on where in the DNA is mutated, on the type of mutation that occurs, on whether the mutation is fixed, etc.)

- the binding between codons and anticodons are always as follows:

A on mRNA binds to U on tRNAT on mRNA binds to A on tRNAG on mRNA binds to C on tRNA and vice versa

Mutagens are substances that damage DNA and can cause permanent changes in the DNA sequence, depending on the ability of the organism to fix the mess.

Mutagen's effect:

Deoxynucleoside triphosphates (dNTPs), which are utilized by DNA polymerases to duplicate DNA, can also be damaged by DNA-damaging agents.

A mutagen could harm the organism by disrupting gene function.A mutagen may alter gene function to the organism's benefit.A mutagen can alter codon-anticodon binding.

Therefore, the final answer is "Option A, B, and D".

GENETICS:

Genetics is the branch of biology that deals with the study of genes and inheritance. Like every subject, genetics possess some terms that can be hierarchically arranged. The terms are in the order:

Nucleotide: Nucleotide is the monomeric unit of nucleic acids made up of three components namely: nitrogenous bases, phosphate group and pentose sugar.

Gene: A gene is a segment of DNA or RNA from an organism's genome that codes for a particular trait.

DNA: DNA is one of the two nucleic acids that stores genetic information in living cells.

Chromosome: Chromosome is a X-shaped structure made up of DNA and proteins tightly woven together.

Hence, the correct listing of genetic terms from smallest to largest is nucleotide, gene, DNA molecule, chromosome.

Answer:

Explanation:

The sequence replication → cell division I → cell division II describes the formation of gametes.

Where does the formation of gametes occur?

Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.

Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.

The gonads are where gametes (germ cells) are made. This process is known as spermatogenesis in males and oogenesis in females. The majority of novel mutations arise during gametogenesis, however males exhibit a higher mutation rate.

There are 40 chromosomes in germ cells of a ferret. How many sex chromosomes are there in a ferret's ovum?

Answers

Answer:

Explanation:

In a mitotic cell division, the number of chromosomes remains constant. It is so because the chromosomes are replicated to produce chromatid which during cell division is equally distributed in all the daughter cells thereby preserving the chromosome number.Both sperm cell and ovum have 23 chromosomes each. It is the fusion of both at fertilization that brings about 46chromosomes seen in somatic cells. These chromosomes are 22pair somatic chromosomes and a pair of sex chromosome (I.e XX or XY).The cells of the body have a diploid number of chromosomes (2N). The diploid number is usually double the haploid number (1N), so if the haploid number of chromosomes is 20, then 2x20=40. So the answer either 40 or 36

To determine the number of sex chromosomes that are there in a ferret's ovum is 2 sex chromosomes.

Given the following data:

Number of chromosomes = 40 chromosomes.

Sex chromosomes can be defined as a pair of chromosomes that are responsible for determining the gender of a living organism i.e whether an organism is either male or female.

To determine the number of sex chromosomes that are there in a ferret's ovum:

Mathematically, the number of chromosomes in an organism is given by the formula:

[tex]Chromosomes = 2N[/tex]

Where:

N is the number of sex chromosomes.

Substituting the given parameter into the formula, we have;

[tex]40 =2N\\\\N=\frac{40}{2}[/tex]

N = 2 sex chromosomes

Answers

Answer:

25% or 0.25

Explanation:

The frequency of the genotype Aa from the population can be calculated from the formula;

Frequency of Aa = number of individuals with Aa/total population

number of individuals with Aa genotype = 23

Total population = 41+23+28 = 92

Hence,

Frequency of Aa = 23/92 = 0.25 or 25%
