When a chromosome has made a copy of itself each of the two strands is called this?
When a chromosome has made a copy of itself, each of the two strands is called a sister chromatid. Sister chromatids are identical copies formed during DNA replication and are joined at the centromere.
Compare chromosome and chromatid?
chromosomes are made of 2 chromatids
A c..... is made up of two c..... arms joined in the middle by a c....?
chromosome, made up of chromatid arms, joined by centromere.
What is each rod in a cells DNA called?
I think it's a chromatid.
What is it called when two chromosomes exchange parts?
mutagenesis occurs
When one chromatid segment has formed a chiasma with a homologous chromatid segment what is the result?
Recombinant chromosomes.
When an area of chromatid is exchanged with the matching area on a chromatid of its homologous chromosomes occurs .?
mutagenesis occurs
What is different between a chromosome and a chromatid?
Chromosome need 2 chromatids but a chromatid is only half of a chromosome
Are the genes on a recombinant chromatid the same as the original chromatid?
No, the genes on a recombinant chromatid are a combination of genes from the original chromatids. During crossing over in meiosis, genetic material is exchanged between homologous chromosomes, resulting in a new combination of genes on the recombinant chromatid.
How many DNA molecule in a chromatid?
Each chromosome is originally made of one DNA molecule.
In a chromosome pair connected by a centromere what is each individual chromosome called?
chromatid
What results in a chromatid formation?
replication
