What are double-stranded chromosomes known as?
Double-stranded chromosomes are known as sister chromatids. They are exact copies of each other, formed during DNA replication and are held together by a specialized region called the centromere. Sister chromatids separate during cell division.
What describes the structure formed wjen a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
Each strand of a double stranded chromosome--9 letter word?
Chromatid-- I think TETRADS-The four chromatids in each cluster during synapsis; formed by the two sister chromatids in each of the two homologous chromosomes.
The formation of a tetrad during meiosis occurs as a result of?
The formation of a tetrad during meiosis occurs as a result of homologous chromosomes pairing up and aligning with each other. This alignment allows for the exchange of genetic material between the homologous chromosomes through a process called crossing over, promoting genetic diversity.
What describes the structure formed when a probe hybridizes to a gene?
A double-stranded DNA structure in which one strand is the probe.
What is the major difference between normal DNA double helix and RNA double helix?
The major difference is that RNA is usually single-stranded while DNA is double-stranded. Additionally, RNA contains uracil as one of its bases instead of thymine found in DNA. RNA is also usually more transient and involved in a wider variety of functions than DNA.
Why is it important the the number of chromosomes is reduced when gametes are formed?
poo come out the bum
Are tetrad and homologous chromosomes the same?
No, tetrad refers to a group of four chromatids that are formed during meiosis by pairing of homologous chromosomes. Homologous chromosomes are chromosome pairs that code for the same traits but may have different alleles.
DNA replication is carried out by a series of?
Enzymes, such as helicase, DNA polymerase, and ligase. These enzymes work together to unwind the double-stranded DNA, synthesize new complementary strands, and seal the gaps in the newly formed strands. This process ensures accurate duplication of the genetic material.
How many chromosomes are in a cell that was formed from a sperm and egg cell?
Twenty-three chromosomes are in a cell that is formed from a sperm and egg cell.
What molecules come together to make a DNA molecule?
Nucleotides which formed double helix.
Does helicase enzymes break the sugar phosphate backbone?
No, helicase enzymes unwind and separate the double-stranded DNA helix by breaking the hydrogen bonds between complementary nucleotide base pairs. They do not break the sugar-phosphate backbone of the DNA molecule.
