Unit 4 Review

Front

What is a Deletion Mutation - Chromosomal?

Back

A type of mutation where a part of a chromosome is deleted, leading to a loss of genetic information.

Front

What is a Deletion - Frameshift mutation?

Back

A mutation that occurs when a nucleotide is deleted from the DNA sequence, causing a shift in the reading frame of the genetic code.

Front

What is the complementary RNA sequence for the DNA strand GTAGTCA?

Back

CAUCAGU.

Front

How many amino acids are coded for by the nucleotide sequence ATG GGA ACT CCA?

Back

4 amino acids.

Front

What is a Duplication Mutation?

Back

A type of mutation where a part of a chromosome is duplicated, resulting in extra genetic material.

Front

What is a nucleotide?

Back

The basic building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a template for translating genetic information from DNA into proteins.

Front

What is a Point Mutation?

Back

A mutation that involves a change in a single nucleotide in the DNA sequence.

Front

What is Translocation in genetics?

Back

A chromosomal mutation where a segment of one chromosome is transferred to another chromosome.
