It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
What else can I help you with?
What process would entail an exchange of chromosome segments between pair 7 and 15?
This process is known as chromosomal crossover or genetic recombination. During meiosis, homologous chromosomes can exchange segments of DNA between each other, resulting in genetic diversity among offspring. This exchange involves the physical swapping of chromosome segments between pair 7 and 15.
When do homologous chromosomes exchange DNA?
Homologous chromosomes exchange DNA during meiosis, specifically in prophase I, during a process called crossing over or recombination. During this stage, homologous chromosomes pair up and form structures called tetrads, where segments of DNA can be exchanged between non-sister chromatids. This genetic exchange increases genetic diversity in the resulting gametes.
What is DNA loosly bound to protein called?
The segments of DNA that are loosly bound to protein are called Chromatin.
Crossing-over is the exchange of reciprocal segments of DNA between homologous chromosomes true or false?
It's true that crossing over is the exchange of reciprocal DNA parts between homologous chromosomes.
What Segments of DNA transferred from parent to offspring are called?
gene
What are the small segments of DNA that control protein formation called?
The small segments of DNA that control protein formation are called genes. Genes contain the instructions for making proteins and are located along the DNA molecule in the cell. They determine the characteristics and functions of an organism by directing the synthesis of specific proteins.
The laboratory procedure for copying selected segments of DNA is?
The laboratory procedure for copying selected segments of DNA is called polymerase chain reaction (PCR). In PCR, the DNA template is heated to separate the DNA strands, then specific primers are added to initiate replication by a DNA polymerase enzyme. The process is repeated multiple times to amplify the DNA segments of interest.
What is the exchange of DNA material at synapsis?
The exchange of DNA material at synapsis is known as genetic recombination. During this process, homologous chromosomes pair up and exchange segments of genetic material through a process called crossing over. This results in the creation of new combinations of genes that are different from the original parental chromosomes.
What way can DNA segments be changed such that genes are altered or mutated?
DNA segments can be changed through a variety of mechanisms, such as point mutations (single nucleotide changes), insertions or deletions of nucleotides, or rearrangements of DNA segments. These changes can alter the sequence of a gene, leading to a mutation that may affect the function or expression of the gene. Factors such as environmental exposures or errors during DNA replication can contribute to these changes.
What is the exchange of genes between homologous pairs of chromosomes?
The exchange of genes between homologous pairs of chromosomes is called genetic recombination. This process occurs during meiosis, where corresponding segments of DNA are exchanged between maternal and paternal chromosomes, increasing genetic variation in offspring.
What are the deleted segments of DNA called?
Deleted segments of DNA are called deletions. Deletions involve the loss of a segment of DNA from a chromosome, which can lead to genetic disorders or changes in an organism's traits. This type of mutation can be caused by errors during DNA replication or exposure to mutagenic agents.
Crossing over occurs in?
Each chromatid can synapse with any one it want/chooses.
