Answer 5

4 cells

Question 6

Order fo the phases of mitosis

Answer 6

Prophase Metaphase Anaphase Telophase

Question 7

3 characteristicts of genes

Answer 7

reproduce themselves, passed down to the next generation, found in nuclear material

Question 8

3 characteristicts of chromosomes

Answer 8

produce RNA, tightly coiled, consist of many genes

Question 9

What are 3 functions of genes

Answer 9

causes a specific trait, produce a particular chain of amino acids (produce protiens), control the activation and deactivation of protein coding genes

Question 10

What are the 3 functions of chromosomes

Answer 10

contain genes, duplicate for cell division, seperate during cell division

Question 11

what is a zygote

Answer 11

a diploid cell formed by joining 2 haploid gametes

Question 12

what is a gamete

Answer 12

haploid cells that unite to form a zygote

Question 13

what is fertilization

Answer 13

The process of forming a zygote, the union of gametes

Question 14

some comparisons between mitosis and meiosis

Answer 14

both make new cells, both deal with cell division

Question 15

diferences between mitosis and meiosis

Answer 15

Mitosis makes two daughter cells while Meiosis makes four, Mitosis is asexual while Meiosis is sexual, In Mitosis daughter cells are identical to the parent cell while in Meiosis they aren’t, Mitosis are diploid while Meiosis are haploid

Question 16

differences between Sexual and Asexual reproduction

Answer 16

sexual requires the joining of 2 haploid gametes while asexual does not, sexual has haploid cells while asexual has diploid cells

Question 17

similarities between Asexual and Sexual reproduction

Answer 17

both are types of reproduction, both lead to the formation of new things

Question 18

3 characteristics of codons

Answer 18

series of 3 nucleotides, found in both DNA and RNA, contains start and stop codons

Question 19

3 functions of codons

Answer 19

used to specify an amino acid, instruct cells to create needed proteins, form the basis of cell communication

Question 20

3 characteristics of DNA

Answer 20

contains sugars, contains a phosphate, contains bases, double helix, double stranded, contains the code of life, bases are bounded by hydrogen bonds

Question 21

3 functions of DNA

Answer 21

stores information, synthesises proteins, contains cellular instructions, helps construct RNA

Question 22

homozygous

Answer 22

both traits were the same

Question 23

heterozygous

Answer 23

the traits received were different

Question 24

3 characteristics of RNA

Answer 24

becomes a copy of DNA during transcription, contain proper series of codons, they are a component of ribosomes, it is single stranded

Question 25

3 functions of RNA

Answer 25

serves as a temporary copy of DNA, produced during transcriptions, serves as structural components of ribosomes
