Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?

Answers

Answer 1
Answer:

Answer:

Translocation

Explanation:

Translocation is a chromosomal defect in which part of a chromosome breaks off and reattaches backward on the same chromosome.

Translocation can happen due to many reasons like:

A) Some of the changes that arise around the time of conception  or production of sperm or egg.

B) The inheritance of altered chromosome from father or mother.

Translocations can be divided into two forms:

  • Reciprocal translocation
  • Robertsonian translocation.

In reciprocal translocations,  fragments of two chromosomes break off from two different places, break and swap each other's segments. While in  Robertsonian translocation one chromosome attached with other.

Hope it help!

use newton's first law of motion to explain why you feel tossed around whenever a roller coaster goes over a hill or through a loop

Answers

Explanation:


A roller coaster is hard to stop because it has a lot of inertia. Inertia can be simplified to, "objects want to keep doing what they are doing." It's when they are forced to do something different that they are doing that is why roller coaster riders experience the float or tossing around of the ride.

Newton's First law of motion:  An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
This is also known as the law of inertia
Anyways,  you feel tossed around because unbalanced forces are acting upon you while riding on a roller coaster.  Hope this helps!

The rough endoplasmic reticulum to created proteins that can be packaged in vesicles.

Answers

Answer:

After mature mRNA is created, it migrates to the cytoplasm then to the rough endoplasmic reticulum to create proteins that can be packaged in vesicles.

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
