What is the region of a chromosome holding the two double strands of replicated DNA together called?
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
What are any types of tissues?
Specialized cells that work together to complete one task is called a tissue
Why is DNA replication called semi conservative?
DNA replication of one helix of DNA results in two identical helices. If the original DNA helix is calledthe "parental" DNA, the two resulting helices can be called "daughter" helices. Each of these two daughter helices is a nearly exact copy of the parental helix (it is not 100% the same due to mutations).DNA creates "daughters" by using the parental strands of DNA as a template or guide. Each newly synthesized strand of DNA (daughter strand) is made by the addition of a nucleotide that is complementary to the parent strand of DNA. In this way, DNA replication is semi-conservative, meaning that one parent strand is always passed on to the daughter helix of DNA.
All organisms are composed of?
All living organisms are composed of structural and functional units that are called cells. Cells are the smallest unit of life that can be replicated.
What is the most important feature in meiosis?
In the most critical feature of meiosis, replicated chromosomes pair and exchange DNA through a process called recombination.
What are the coils of dna called?
Double helices .
What is the region of a chromosome holding the two double strands of replicated DNA together called?
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
The failure of replicated chromosomes to separate is called?
The failure of replicated chromosomes to separate is called nondisjunction. This will cause extra or missing chromosomes in the daughter cells.
What is A strand of replicated DNA formed during prophase called?
chromatid
Does meiosis have an interphase where chromosomes are replicated?
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.
What are different organs that work together to complete a series of tasks called?
An organ system.
Which term describes two recently replicated DNA strands that are joined together just before cell division?
The term that describes two recently replicated DNA strands that are joined together just before cell division is "sister chromatids." Each sister chromatid is an identical copy of the original DNA molecule and is held together at a region called the centromere. During cell division, the sister chromatids separate and are distributed to the daughter cells.
When is DNA duplicated and why is DNA duplicated?
DNA is replicated in the process called Mitosis and Meosis. DNA is replicated to make more cells. Your body will make cells if you have a cut, grow, etc..
What are any types of tissues?
Specialized cells that work together to complete one task is called a tissue
What happens atoms combine?
uncomplete atoms attract each other sort of like a magnet. when they 'stick' together they are then called a molecule but there are atoms that do not form together because they are complete. they are called Noble Gases.
Atoms combine when what happens?
uncomplete atoms attract each other sort of like a magnet. when they 'stick' together they are then called a molecule but there are atoms that do not form together because they are complete. they are called Noble Gases.
The process where replicated homologous chromosomes are linked to form tetrads is called?
Meiosis Stage II.
