What else can I help you with?
Is the genetic material in living organisms double stranded, as found in DNA or RNA?
Yes, the genetic material in living organisms can be double stranded, as seen in DNA, or single stranded, as seen in RNA.
Can the nucleus and the nucleolus be seen during inter-phase?
yes
Are polar bodies visible in a cats ovary?
Yes, polar bodies can be seen in a cat's ovary during oogenesis. Polar bodies are small cells that contain genetic material expelled during the process of forming an egg cell. They play a role in reducing the genetic material in the egg to facilitate fertilization.
The moon cannot be seen from Earth during this phase?
New moon.
A synaptonemal complex would be found during?
A synaptonemal complex is typically seen during meiosis, specifically in prophase I. It helps to facilitate the pairing of homologous chromosomes and the exchange of genetic material between them through crossing over.
22 A biologist is measuring the amount of DNA in cells growing in the laboratory When would the quantity of DNA in a cell would be seen to double?
The DNA in a cell would be seen to double during the S phase of the cell cycle. Let us recall that the cell cycle consists of the following phases: G1, S, G2 and M Here, S stands for synthesis - where there is a synthesis of new organelles and a doubling of the DNA content of the cell prior to cell division (or mitosis)
What moon phase is mostly visible during the day?
The phase of the moon that is mostly visible during the day is the waxing gibbous phase. During this phase, the moon is more than half illuminated and is positioned in the sky such that it can be seen in the afternoon and early evening. This visibility occurs because the moon is rising in the east while the sun is setting in the west, allowing both to be seen simultaneously.
What is it called when homologous chromosomes trade alleles?
Crossing-over is when segments of homologous chromosomes switch places. This process occurs during prophase I of meiosis and results in recombinant chromosomes. This adds to the variation seen in offspring.
Why do we have a mix of our mother's and father's characteristics?
We inherit a mix of our mother's and father's characteristics through a process called genetic recombination. This occurs during the formation of reproductive cells (eggs and sperm) when segments of genetic material from each parent combine to create a unique genetic blueprint for the offspring. This mixing of genetic information contributes to the variability and diversity seen in offspring.
Asexually reproducing organisms pass on hereditary information as?
Asexually reproducing organisms pass on hereditary information through exact copies of their genetic material, such as through mitosis or budding. There is no genetic recombination or mixing of genetic material as seen in sexual reproduction.
Why the formation of chasmata is an important feature of meiotic division?
The formation of chiasmata during meiotic division plays a crucial role in genetic recombination. Chiasmata physically link the paired homologous chromosomes, allowing for the exchange of genetic material through crossing over. This process increases genetic diversity and contributes to the variation seen in offspring.
Can chromosones be seen clearly after the G2 phase?
chromosomes can be seen because of g1 phase and s phase.
