What enzyme works to add DNA to ends of chromosomes in rapidly cells such as those found in an embryo to prevent genes from being lost durintg replication?
Telomerase is the enzyme responsible for adding repetitive DNA sequences to the ends of chromosomes, known as telomeres. This helps prevent the loss of genes during DNA replication in rapidly dividing cells, such as those found in embryos. Telomerase maintains the length of telomeres, ensuring chromosomal stability and integrity.
What is the enzyme that replicates the end of chromosomes?
Telomerase is the enzyme that replicates the end of chromosomes, specifically the telomeres. Telomeres are protective caps at the ends of chromosomes that shorten with each cell division, and telomerase helps maintain their length to prevent loss of genetic information and cellular senescence.
What does the telomerase enzyme do?
Telomerase maintains the telomeres of chromosomes in order to prevent cell death. This enzyme added sequences onto the ends of the chromosomes, thereby preventing extreme shortening and loss of genetic material. In a way, telomerase would give cells immortal life, by continuously regenerating its ends. However, telomerase are usually inactive in the human body because normal cells do not divide frequently, and therefore, the chromosomes do not shorten.
The enzyme telomerase solves the problem of replication by?
Telomerase helps solve the problem of DNA replication by adding repetitive sequences to the ends of chromosomes, known as telomeres. This prevents the loss of important genetic information during each round of cell division. By preserving the length of telomeres, telomerase maintains the stability and integrity of chromosomes.
What is the function of fertilization?
Enzyme to penetrate outer layer of egg.

What provides nourishment for the human embryo?
The mother does. The embryo attaches to the uterine lining (called implantation) then secretes an enzyme to breakdown the cells of the lining as it burrows into the uterus. Maternal uterine cells then develop and surround the entire embryo, soon maternal blood vessels unite with the embryo to nourish it and remove waste products. This occurs about one week after fertilization and will provide nourishment throughout the first trimester until the embryo reaches the fetal stage at which time the placenta takes over through the umbilical cord.
What directs enzyme production?
Enzyme production is directed by gene regulation mechanisms within the cell. Specific genes are transcribed and translated to produce enzymes in response to signals such as metabolite concentrations, environmental conditions, and cellular needs. Factors such as transcription factors, gene promoters, and enhancers play crucial roles in regulating enzyme production.
What conditions can be drawn about the action of the enzymes as the temperature increases?
As temperature increases, enzyme activity generally increases up to a certain point (optimal temperature) where the enzyme works most efficiently. Beyond the optimal temperature, the enzyme's activity rapidly declines due to denaturation. Extreme temperatures can disrupt the enzyme's active site, altering its shape and preventing it from catalyzing reactions effectively.
What is starch used for during germination?
In the endosperm of a seed, there is a storage of starch which provides energy, required during germination. To tap into this energy and make it available to the embryo of the seed, the starch is first hydrolysed by an enzyme (alpha amylase) and converted into maltose (a disaccharide), then in turn, maltose is hydrolysed by the enzyme maltase to form glucose (a monosaccharide). The resulting glucose can then provide energy in the form of ATP and be used for growth by the embryo of the seed. Hope this helps.
What happens to hydrogen peroxide in the body?
It gets rapidly broken down into oxygen and water by the enzyme peroxidase.
What is the chemical telomerase used for?
In science, the chemical telomerase is enzyme that is part of the DNA structure in humans. The chemical is used to help hinder the loss of important DNA in the ends of chromosomes.
