This enzyme unwinds the DNA double helix at the replication fork.

Helicase

100

The presence of an extra chromosome 21 in a karyotype leads to this genetic condition.

Downs syndrome

100

This molecule carries the genetic instructions from DNA to the ribosome for protein synthesis.

mRNA

100

This is the largest continent by land area.

Asia

This organelle is known as the powerhouse of the cell, producing energy in the form of ATP.

Mitochondria

200

This enzyme adds nucleotides to the growing DNA strand during replication.

DNA polymersae

200

A karyotype of a male with 47,XXY indicates this genetic disorder, which affects male development.

Kleinfelters

200

This cell organelle is the site of translation, where proteins are synthesized.

Translation

200

This ancient civilization built the pyramids of Giza.

Eygptians

This system is responsible for transporting nutrients, gases, and waste products throughout the body and includes the heart, blood vessels, and blood.

Circulatory system

300

Because DNA strands run in opposite directions, replication occurs continuously on the leading strand and in fragments on this strand.

Lagging strand

300

Unlike most chromosomal disorders caused by an extra chromosome, this condition results from the absence of one X chromosome in females, producing a 45,X karyotype.

Turners syndrome

300

This three-nucleotide sequence on mRNA specifies a particular amino acid or a stop signal during translation.

codon

300

This is the most abundant gas in Earth's atmosphere.

Nitrogen

This type of microscope provides a detailed 3D image of the surface of a specimen by scanning it with a fine probe.

scanning electron microscope (SEM)?

400

These short fragments, found on the lagging strand, are later joined together by DNA ligase.

okazaki fragments

400

Individuals with Down syndrome typically have 47 chromosomes, while individuals with Turner syndrome have this many.

45

400

This type of RNA has an anticodon that pairs with an mRNA codon and carries the corresponding amino acid to the ribosome.

tRNA

400

This English playwright, known as the 'Bard of Avon,' wrote Hamlet and Romeo and Juliet.

William Shakespeare

400

This swimmer holds the record for the most Olympic gold medals won by any athlete in history.

Michael phelps

500

This term describes the model of DNA replication in which each new DNA molecule consists of one original strand and one new strand.

semi conservative

500

Chromosomes with centromeres located near the end, creating one very short and one long arm, are called this. Chromosomes 13, 14, 15, 21, and 22 fall into this category and are involved in Robertsonian translocations.

acrocentric

500

In RNA, this nucleotide replaces thymine and pairs with adenine during transcription, forming two hydrogen bonds.

U -Uracil

500

This fundamental force is responsible for holding the nucleus of an atom together, overcoming the repulsion between protons.

This country has won the most FIFA World Cup titles in men's soccer.
